State the general trend in first ionization energy as the elements in Period 3 are considered from left to right.

The pattern for ionization energy is that it increments from the base to the top and from the left to one side. Thusly, as the components in Period 3 are considered from left to right, the primary ionization energy will increment since the range diminishes toward this path.

Explanation:

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.
