How the positions of elements in the periodic table help you to predict its chemical properties? Explain with an example.

In period 2, element $\mathrm{X}$ is to the right of the element $\mathrm{Y}$. Then, find which of the elements have:

Low nuclear charge.

In period 2, element $\mathrm{X}$ is to the right of the element $\mathrm{Y}$. Then, find which of the elements have:

Low atomic size

In period 2, element $\mathrm{X}$ is to the right of the element $\mathrm{Y}$. Then, find which of the elements have:

High ionization energy

In period 2, element $\mathrm{X}$ is to the right of the element $\mathrm{Y}$. Then, find which of the elements have:

High electronegativity

In period 2, element $\mathrm{X}$ is to the right of the element $\mathrm{Y}$. Then, find which of the elements have:

More metallic character
