An atom of an element has four more electrons than a Sodium ion. Name this element

An atom of an element has four more electrons than a Sodium ion. Name this element, make up the electronic formula of the atom.

Sodium Na (0) has the following electronic configuration:

1s2 2s2 2p6 3s1 There are 11 electrons in total.

What is sodium ion? The sodium atom becomes ionic when it donates an electron, that is, Na (+).

The following formula will correspond to it:

1s2 2s2 2p6 3s0. There are 10 electrons in total.

An element that has 4 electrons more than a sodium ion will have the formula:

1s2 2s2 2p6 3s2 3p2. The total is 14 electrons, which corresponds to the condition of the problem. According to the periodic table of D.I. Mendeleev, this element is silicon (Si).
