Answer: Sodium valance electron is 1 as its electronic configuration is 2 8 1 and chlorine valance electron is 7 as its electronic configuration is 2 8 7.
Explanation:
Answer:
valency of sodium= +1 and valency of chlorine= -1
Explanation:
sodium (11)= 2,8,1
so, the last valance electron is it's valency= +1
chlorine (17)= 2,8,7
so, to find it's valency we have to subtract the last valence electron to get valency
= 8-7= -1
* always remember the valency is always 1,2,3 and 4 and the element having valency 4 is metalloid.
* metal have positive electron and non-metal have negative electron.
