Question

hey please give me correct answer its very urgent.
1.how many electrons present in the outermost shell of alkali metal?
2.what is the valency of carbon?
if you know then only answer please ......

Answer 1

1) 1 electron..

2) carbon valency--◆4

Answer 2

1.according to the electronic configuration the electrons are filled in these elements and final one electron occupies the valence s orbital.this makes alkali metals highly reactive in nature .

2.A carbon atom has four electrons in its outermost valence shell. So, it needs four more electrons to complete its octet. A carbon atom completes its octet only by sharing its valence electrons with other atoms. As a result, a carbon atom forms four covalent bonds by sharing valence electrons with other atoms.
