An exothermic process is a process in which heat is:
Absorbed , released, stored, doubled

Explanation:

Metals usually have stronger electron affinity than non-metals:

In the periodic table, the trend of electron affinity is that it increases from left to right across the period and decrease down the group.

False

Noble gas elements have a very large value for electron affinity:

Electron affinity is the change in energy of an atom when an electron is added. Noble gases already have a complete octet configuration hence there is no reason to accept any electrons. This makes their electron affinity value less than or equal to zero.

False

Negative anions have a larger ionic radius than the atomic radius of their neutral atom:

Neutral atoms that gain electron are referred to as anions. The extra electron increases the electron-electron repulsion which pushes the electrons further apart and finally increased radius.
