Question

I cannot understand how just by knowing the electronic configuration of an element we can identify whether it is a metal or non-metal ? Can you please explain ? And in detail please and fast plzzz.....

Answer 1

see if the last number of ec is less than 4 that means it can lose electrons this it gains positive charge so it is a metal and if it is more than four it is nonlethal as it gains electrons to attain stability.

Answer 2

If we know the electronic configuration we will know the element and we also know that 1 group elements are alkali metals 2group elements are known alkali earth metals .So with electronic configuration also we can identify whether it is metal or non metal
