(a) Write its electron configuration.


(b) State the group to which 'M' belongs?


(c) Is 'M' a metal or a non-metal?


(c) Write the formula of its chloride.

(a)The Electronic configuration can be written as 2, 8, 1

(b) The element has 1 valence electron, so, it will belong to group 1


(c) Elements with valence electrons 1,2 and 3 are metals and since 'M' element has 1 valence electron. So, it is a metal.
