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 draw isometric diagram of its atom showing the distribution of electrons in the cells

Answer 1

14-atomic number
4-valency

Answer 2

hey there are shells named k. l .m. n .
number of electrons in M shell equals to 4
so its electronic configuration is 2, 8, 4
so the element is silicon. ...
its valency is 4....
