Question

i) Draw the sketch of Bohr model of atom

ii) What do you mean by ATOMIC NUMBER.

iii) How many electrons can be accommodated in n=3 shell in Bohr model of atom.​

Answer 1

Answer:

ii) ATOMIC NUMBER:

The atomic number or proton number of a chemical element is the number of protons found in the nucleus of every atom of that element. The atomic number uniquely identifies a chemical element. It is identical to the charge number of the nucleus.

iii) 18

Answer 2

i) The Bohr model of the atom proposes that the mass of the atom resides in its nucleus and the electrons move around it in definite shells called orbits.

Kindly refer to the attachment for the sketch of the Bohr model of an atom.

ii) Atomic number refers to the number of protons present in the atom.

For neutral species,

Number of electrons= Number of protons=  Atomic number

iii) According to the 2n² rule,

The maximum number of electrons that can be accommodated in n= 3,

2(3)² = 18
