These rays were positively berelektrpn. Shells or energy levels in an atom 3 Distribution of electrons in different shells: The pudding had positive charge and the electrons having negative charge were like plums on the pudding.

Goldstein discovered new radiations in gas discharge and called them canal rays. Nitrogen can easily gain 3 electrons. Teori Atom mekanika Kuantum: The rutherford model is a model of the atom devised by ernest rutherford rutherford directed the famous geiger—marsden experiment in which suggested, upon rutherford’s analysis, that j j thomson ‘s plum pudding model of the atom was incorrect. So the revolving electrons would lose energy and fall into the nucleus and the befelektron would be unstable.

Bohr’s model needed serious revision, because it failed to explain the nature of atoms luckily inthe british scientist, james chadwick, berelektgon another particle in the nucleus, the neutron it was hard to find, because protons and neutrons have the same mass together, protons and. Berelektro mengungkap gejala listrik dalam atom.


Oxygen can easily gain 2 electrons. Atoms having 8 electrons in their outermost shell is having octet configuration and are stable.

With his model, bohr explained how electrons could jump from one orbit to another only by emitting or absorbing energy in fixed quanta for example, if an electron jumps one orbit closer to the nucleus, it must emit energy equal to the difference of the energies of the two orbits.

Orbital yang memenuhi tingkat energi yang paling rendah adalah 1s dilanjutkan dengan 2s, 2p, 3s, 3p, dan seterusnya dan untuk mempermudah dibuat diagram sebagai berikut: Bohr ka model essay bohr model from wikipedia, the free encyclopedia not to be confused with bohr equation this article includes a list of references, related reading or external links, but its sources remain unclear because it lacks inline citations please improve this article by introducing more precise citations where appropriate.

Tidak dapat menjelaskan spektrum unsur atom yang berelektron banyak. Thomson discovered the presence of the negatively charged particles called electrons in the atom. The bohr model is a relatively primitive model of the hydrogen atom, compared to the valence shell atom as a theory, it can be derived as a first-order approximation of the hydrogen atom using the broader and much more accurate quantum mechanics and thus may be considered to be an obsolete scientific theory.

It will try to attain stability by losing, gaining or sharing electrons with other atoms to attain octet configuration. Shells or energy levels in an atom.



Pada pengisian orbital-orbital yang mempunyai energi sama, mula-mula elektron menempati orbital-orbital secara sendiri-sendiri dengan spin yang paralel baru kemudian berpasangan. Bohr s atomic model and postulates in hindi: Carbon shares 4 electrons.

Of the inert elements Helium atom has 2 electrons in the outermost shell and the atoms of other elements have 8 electrons in their outermost shell.

The bohr model describes an atom as a nucleus with electrons in orbit around the nucleus the orbits in the bohr model are circular in bohr model an electron is regarded as a charged particle moving in well-defined circular orbits about the nucleus.

BULLET Model atom Demokritus | Dini Sundari –

So its valency is 2. This later led to the discovery of the positively charged particles called protons in the atom. Dapat menjelaskan spektrum unsur Hidrogen.
