Question

draw the atom structure and explain it.​

Answer 1

Answer:

Draw your protons and neutrons. Erase the "C" in the center circle, and draw in your protons. Since protons are the same as the amount of electrons, you just draw 6 protons. ... Neutrons are simply equal to the atomic mass minus the number of protons.

Answer 2

Bohr's model is the most widely accepted atomic structure model.

Explanation:

• Atomic structure refers to the structure of an atom comprising a nucleus (centre) in which the protons (positively charged) and neutrons (neutral) are present.

• The negatively charged particles called electrons revolve around the centre of the nucleus.

• The atomic structure of an element refers to the constitution of its nucleus and the arrangement of the electrons around it.
• Primarily, the atomic structure of matter is made up of protons, electrons and neutrons.

• The protons and neutrons make up the nucleus of the atom, which is surrounded by the electrons belonging to the atom.
• The atomic number of an element describes the total number of protons in its nucleus.

Bohr's atomic theory

It is based on Planck's theory of quantization. Postulates of this atomic model are given below:

• The electrons inside atoms are placed in discrete orbits called “stationery orbits”.

• The energy levels of these shells can be represented via quantum numbers.

• Electrons can jump to higher levels by absorbing energy and move to lower energy levels by losing or emitting its energy.

• As longs as, an electron stays in its own stationery, there will be no absorption or emission of energy.

• Electrons revolve around the nucleus in these stationery orbits only.

• The energy of the stationary orbits is quantized.

Limitations of this model:

• Bohr’s atomic structure works only for single electron species such as H, He+, Li2+, Be3+...
• When emission spectrum of hydrogen was observed under a more accurate spectrometer, each line spectrum was seen to be a combination of number of smaller discrete lines.
• Both Stark and Zeeman effects couldn’t be explain using Bohr’s theory.
