Question

hey its 50 marks question u can get it just answer bohr bury theorem.

Answer 1

Bohr nd bury scheme - important rules. The outermost shell of an atom cannot accommodate more than 8 electrons, even if it has a capacity to accommodate more electrons. This is called very important rule or also called octet rule. The presence of 8 electrons in the outermost shell makes the atom very stable.
Hope you understand ☺

Answer 2

Bohr Bury Theorem Rules :

Most extreme number of electrons that can be obliged in a shell is given by 2n2 where n = shell number

For first vitality level, n = 1Maximum number of electrons in first vitality level = 2n22 x (1) 2 = 2

For second vitality level n = 2Maximum number of electrons in the second vitality level = 2n22 x 22 = 2 x 4 = 8

For third vitality level n = 3Maximum number of electrons in the third vitality level = 2n2= 2x(3) 2= 2 x 9 = 18

For fourth vitality level n = 4Maximum number of electrons in the fourth vitality level = 2n2= 2x(4) 2= 2x16 = 32
