give the meaning of :Atomic Radius, Ionisation Potential, Electron Affinity and Electronegativity
Answers
Explanation:
Atomic radius is the radius of atom including the nucleus along with the electrons
Ionisation potential - The ionization energy or ionization potential is the energy necessary to remove an electron from the neutral atom. It is a minimum for the alkali metals which have a single electron outside a closed shell.
Electron Affinity - The electron affinity of an atom or molecule is defined as the amount of energy released when an electron is attached to a neutral atom or molecule in the gaseous state to form a negative ion
Electronegativity-Electronegativity is a measure of an atom's ability to attract the shared electrons of a covalent bond to itself. ... If the two atoms of the bond are of equal electronegativity, the electrons are equally shared.

Answer:
➩ Atomic Radius :
It is the distance between the centre of the nucleus and the outermost shell of the atom.
➩ Ionisation Potential [I.P.] :
It is the amount of energy required to remove an electron from the outermost shell of an isolated gaseous atom.
➩ Electron Affinity [E.A.] :
It is the amount of energy released when an atom in the gaseous state accepts an electron to form an anion.
➩ Electronegativity [E.N.] :
It is the tendency of an atom to attract electrons to itself when combined in a compound.
