Question

An atom of an element has 4 electrons in the outermost M shell. What will be the atomic number of this element ?Name this element .Find the valency of this element .pls. ..any 1

Answer 1

K shell - 2 electrons
L shell - 8 electrons
M shell - 4 electrons
Z=total no. of electrons=14=Silicon
The Valency of this element is 4.So it forms covalent bonds.

Answer 2

it is silicon
valency of silicon 4
atomic no of silicon 14

hope this helps you
