Question

Considering the electronic configuration of atoms which atom with
the given atomic number will be the most stable one?
(b) 8
(c) 10​

Answer 1

Answer:

b. 10 is your correct answer

Answer 2

Considering the electronic configuration of atoms which atom with the given atomic number will be the most stable one?

(a)6

(b) 8

(c) 10

(d) 12

The electronic configuration will be most stable for the atomic number (c) 10.

• As we know, half-filled and fully-filled electronic configurations are the most stable.
• If the valence shell of an atom have 8 electrons the atom is stable.
• Noble gases are most stable due to filled shells as they have no tendency to gain electrons
• For atomic number 10, the electronic configuration will be 1s² 2s² 2p6. here, p has filled shell.
• For atomic number 8, the electronic configuration will be 1s² 2s² 2p4. here, p has neither a half-filled nor filled shell.
