short answers

Answer 1

• Atomic Radius: The atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons, typically measured in picometers (pm) or angstroms (Å). It generally increases down a group and decreases across a period in the periodic table.

• Electronegativity: Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond. It is dimensionless and is often represented on the Pauling scale, where higher values indicate stronger attraction for electrons.

• Ionization Energy: Ionization energy is the amount of energy required to remove an electron from a neutral atom in its gaseous state. It generally increases across a period and decreases down a group in the periodic table.
