Isi dengan Judul Halaman Terkait Atomic Atom was smallest part from an indissoluble element again with ordinary chemical reaction. And so do that atom from an element can form or interaction to form a compound. Hal.: 4 Isi dengan Judul Halaman Terkait

Isi dengan Judul Halaman Terkait Lanjutan Every atom lapped over to atomic nucleus which haves positif charge encircled by electron particle which haves negative charge. In core also there is other particle of which is not charged or neutral, pays attention to Gambar 3.1 Picture 3.1 Hal.: 5 Isi dengan Judul Halaman Terkait

Isi dengan Judul Halaman Terkait Electron Atom built by three particles that is electron, proton and neutron. Electron is particle loading negative electrics and given [by] symbol with letter (e), -1.6 × 10⁻¹⁹ Coulomb, negative sign at number(-) to indicate that electron haves negative charge. Electron has mass equal to 9.10 × 10⁻31 Kg. Hal.: 6 Isi dengan Judul Halaman Terkait

Isi dengan Judul Halaman Terkait Proton Proton is second base particle, which located in in atomic nucleus and haves positif charge. Proton charge equal to charge of electron equal to 1.6 × 10-19 Coulomb having sign positive Based on result of calculation known [by] mass a proton is 1.673 × 10-27 Kg. This thing indicates that bigger proton mass around 1800 times mass an electron. Hal.: 7 Isi dengan Judul Halaman Terkait

Isi dengan Judul Halaman Terkait neutron Neutron, be base particle that is third, and located in atomic nucleus together with proton. Neutron doesn't charge electrics, but neutron has mass that is 1.675 × 10-27 Kg, this equivalent mass with proton mass. Hal.: 8 Isi dengan Judul Halaman Terkait

Isi dengan Judul Halaman Terkait Continuation To be more clarifies again about position of elementary particle in an atom, we took example if an element had 6 proton, 6 electron and 6 neutron hence In atomic nucleus would there is 6 proton and 6 neutron encircled by 6 electron to see Gambar 3.2. Picture 3.2 Hal.: 9 Isi dengan Judul Halaman Terkait

Isi dengan Judul Halaman Terkait Atom Symbol Writing of atom symbol express existence of proton, electron, neutron as in under this. In general writing of atom sign is ZXA where X it is name of atom A : mass number is number of protons and neutron and Z : atomic number is number of protons or number of electrons.

Isi dengan Judul Halaman Terkait Example Simplest element is hydrogen with letter symbol H, what has number of protons and electron one fruits, and doesn't have neutron with atom symbol presented at picture 3.3. Picture 3.3 Hal.: 11 Isi dengan Judul Halaman Terkait

Isi dengan Judul Halaman Terkait Continuation In existence nature of hydrogen atom is not only like ₁H¹ but there are still other form is detrium and tritium written down, ₁H² ,₁H³ mean there are two element of hydrogen having mass to differ in. For hydrogen atom that is first, has each 1(satu) proton, 1 ( one) electron and 1 ( one) neutron. Differs from second hydrogen atom, has 1(satu) proton and 1 ( one) electron, but number of its(the neutrons counted 2 ( two) fruit. To be more sharpness pays attention to Gambar 3.4. Hal.: 12 Isi dengan Judul Halaman Terkait

Isi dengan Judul Halaman Terkait ISOTOPE With existence of this inferential difference that element can have number of the same electrons and proton, and differs in in its(the neutron, so that this element has isotope. Hal.: 13 Isi dengan Judul Halaman Terkait

Isi dengan Judul Halaman Terkait ISOTON Something else also happened for example if two element had number of the same neutrons, but differs in in the case of proton amounts and electron like the one shown by ₆C¹³, ₇N¹⁴. For element C ( Carbon) has 6 ( six) electron and 6 ( six) proton and 7 ( seven) proton. For element N ( Nitrogen) has proton, the same electron and neutron that is 7 ( seven) fruit. Condition of where two element has number of the same neutrons told as isotope ( Picture 3.5). Hal.: 14 Isi dengan Judul Halaman Terkait

Isi dengan Judul Halaman Terkait ISOBAR In other case also happened where two element to have the same mass, but differs in in the case of its(the mass number, like at unsur₂₇Co⁵⁹, ₂₈Ni⁵⁹, this thing happened because good of element Co ( Kobal) and also Ni ( Nickel) has number of different protons and neutron. But number of its(the protons and neutron is same, for Co, there are 27 protons and 32 neutrons, while Ni has 28 protons and 31 neutrons, condition of where same atomic mass called as with isobar. Hal.: 15 Isi dengan Judul Halaman Terkait

Isi dengan Judul Halaman Terkait Conclusions From example of isotope, isotope and isobar, we can draw some conclusions: 1. Isotope only happened because neutron difference, same in the case of its(the proton amounts and electron and isotope only happened at the same element. 2. Isotope happened because there is equality in the case of neutron amounts, but differs in in number its(the proton and electron, and happened at different element. 3. Isobar happened equality in atomic mass that is its(the proton amounts and neutron, but differs in every proton amounts, its(the electron and neutron, isobar happened at different element. 4. Difference of one element to other element determined by its(the proton amounts. To be more his(its easy to comprehending visible conclusion of difference from isotope, isotope and isobar like at Picture 3.6. Hal.: 16 Isi dengan Judul Halaman Terkait

Development Of Atomic Theory Atom came from atomos meaning Greek cannot be in for again. This understanding doesn't get out of atom concept result of fruit of idea Demokritus (460-370 S.M). Hal.: 17 Isi dengan Judul Halaman Terkait

Isi dengan Judul Halaman Terkait Dalton Atomic Theory Understanding about atom is smallest part of a matter is base utilized by John Dalton ( 1805). He develops atomic theory based on conservation laws of mass ( Lavoisier) and permanent comparison law ( Proust). Dalton submits that 1) Every matter compiled by small particle so-called with atom 2) Atom is a real small solid ball 3) Element is matter which consist of atom that is conspecific and differs from atom from other element. 4) Compound is matter compiled by two or more atom type with certain comparison 5) Forming of compound through chemical reaction which is processing settlement from atomatom is involving in reacting Hal.: 18 Isi dengan Judul Halaman Terkait

Weakness From Dalton Atomic Theory Atomic theory submitted by Dalton, be not able yet to answer phenomenon about related is electrics, known that many condensations which can send electric current. Thereby atom still containing other particle. This weakness pushs other scientist to improve;repair atomic theory Dalton. Hal.: 19 Isi dengan Judul Halaman Terkait

Isi dengan Judul Halaman Terkait Atomic Theory Thomson Atom is ball which haves positif charge, and electron spread over surface [by] it, like bread is sowed [by] currant or like cake onde - onde where its(the surface spread over sesame, sees gambar 3.8. Hal.: 20 Isi dengan Judul Halaman Terkait

Atomic Theory Rutherford Atom consisted of atomic nucleus which haves positif charge and encircled by elektronelektron which haves negative charge. Peripatetic electron encircles core with trajectory which is in the form of circle or ellipse, sees gambar 3.9. Hal.: 21 Isi dengan Judul Halaman Terkait

Weakness Of Atomic Theory Rutherford The Rutherford theory many getting expostulation, if electron moved encircles core, hence electron will discharge or transmits energy so that energy owned by electron over and over will decrease and causes its(the trajectory is more and more old smaller and in a moment electron will fall into core. The Rutherford theory cannot explain this phenomenon. Hal.: 22 Isi dengan Judul Halaman Terkait

Isi dengan Judul Halaman Terkait Atomic Theory Bohr 1. Atom lapped over to core to have positif charge and encircled by electron which haves negative charge. 2. Electron encircles atomic nucleus at certain orbit and stationary ( permanent), with certain energy level. 3. Eelektron at certain orbit can make a move is higher with permeating energy. On the contrary, electron can make a move from higher level orbit to low by discharging energy. 4. In the situation normal ( without external influence), electron occupies low energy level ( called as level of base = ground state) Hal.: 23 Isi dengan Judul Halaman Terkait
