As you progress down the group:- Atomic radius increases, therefore there is more electron shielding.- There is an increase in the nuclear charge, however it is outweighed by the increase in shielding.- I...

Le Châtelier's principle is that when a system has reached a dynamic equilibrium the position of equilbrium will move to resist any change that is imposed on it.

For exampl...

Oxidation is the loss of electrons from a molecule, atom, or ion. This corresponds to an increase in the oxidation number of the molecule, atom, or ion.

Atoms of the same element possessing the same numbers of protons and electrons, but different numbers of neutrons in the nucleus.

As we go from Li to F, atomic radius of the atoms will DECREASE. This is due to increased nuclear charge (number of protons within each atom). Although the number of electrons also increases, each addi...
