Question

an atom of an element has four electron in the outermost M shell what will be the atomic number of this element name this element by in the valency of this element draw a schematic diagram of its atom showing the distribution of electrons in its shlls

Answer 1

carbon atomic no. is 6

Answer 2

the element must be silicon
element : Si
atomic no. :14
electronic configuration :-
k shell = 2
L shell= 8
M shell= 4
valence electrons= 4
valency=4(it forms covalent or sharing bond)
