Question

explain Bohr- Bury principle

Answer 1

Bohr- Bury principle is also known as octet rule.. The octet rule refers to the tendency of atoms to prefer to have eight electrons in their valence shell either by transfer (gaining or losing) of valence electrons from one atom to another or by sharing of valence electrons.

Answer 2

according to this rule.

1 .Maximum number of electrons that can be accommodated in a shell is given by 2n2 where n = shell number

2 .For 1st energy level, n = 1Maximum number of electrons in 1st energy level = 2n22 x (1) 2 = 2

3. For 2nd energy level n = 2Maximum number of electrons in the 2nd energy level = 2n22 x 22 = 2 x 4 = 8For 3rd energy level n = 3Maximum number of electrons in the 3rd energy level = 2n2= 2x(3) 2= 2 x 9 = 18For 4th energy level n = 4Maximum number of electrons in the 4th energy level = 2n2= 2x(4) 2= 2x16 = 32
