Question

Carbon atomic number 6 and silicon atomic number 14 are elements in the same group of the periodic table give the electronic arrangement of the carbon and silicon atom and state the group in which these elements are present 0th

Answer 1

carbon atomic number is 6. So it has two shells and its electronic configuration is 2,4 and lies in period 2.

Silicons atomic number is 14 so it has 3 shells and its electronic configuration is 2,8,4.

As both of them have 4 electrons in their outermost so both of them lie in group 14 or 3A
