a) 12
b) 14
c) 13
d) 11
Sodium has.………..electrons in its valence shell.
a) 1
b) 12
c) 11
d) 9
Sodium has tendency to attain the electronic configuration of …….
a) helium
b) argon
c) neon
d) magnesium
Explanation:Sodium has 11 electrons and 1 electron in its valence shell so it will have tendency to lose 1 electron and will attain the electronic configuration of Neon which has 8 electron in its valence shell.
