A neutral atom has two electrons with n=1, eight electrons with n=2, six electrons with n=3. assuming this element is in its ground state, supply the following: atomic number, total number of s electrons, total number of p electrons, total number of d electrons, is this a metal, metalloid, or nonmetal?

Solutions

Expert Solution

The total number of electrons is

The total number of electrons is 16. Assuming the element in ground state, the total number of electrons is equal to the total number of protons. It is also equal to the atomic number.

Hence, the total number of protons is 16 and the atomic number is also 16.

The electronic configuration of the atom is

The total number of s electrons is

The total number of p electrons is

The total number of d electrons is 0.

The valence shell electronic configuration is . Hence, the element is a p block element. It is a non metal. It is sulphur. It belongs to third period and group VIA of the periodic table.
