Question

what are ions ? Write the Symbol of Sodium ion and chlorine ion?​

Answer 1

Answer:

1.Ions simply means charged species.

2.i ) Chlorine

Atomic No. = 17

Electronic Confiragation : K - 2, L -8, M - 7

Valence = 8-7 = 1            (Octet)

Therefore Chlorine is Cl^+1

Same for sodium

ii) Atomic No. = 11

Electronic Confiragation = K-2, L-8, M-1

Valence = 1

Sodium is Na^-1
