Determine the number of protons neutrons and electrons in 3216s2

Number of protons = 16

Number of neutrons = 16

Number of electrons = 18

Explanation:

The atom given is (32,16)S_2.

This simply Sulphur atom.

What (32,16)S_2 implies is that;

Atomic number = 16

Mass number = 32

Now atomic number means number of protons present in the atom

While mass number means number of sum of protons and neutrons present in the atom

Thus;

Number of protons = 16

Number of neutrons = 32 - 16 = 16

Now, for a neutral atom, number of protons is equal to number of electrons.

However, in this case it's not neutral but has a charge of -2.

Thus,

Number of electrons = 16 + 2 = 18 electrons

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
