Why H3O+, NH4+, Na+, and Ca2+ are not electrophiles?
Organic Chemistry
Why are larger atoms polarizable? What is their effect on the Debye force?
If the size of a nonpolar atom is greater, it means that the atom has a higher number of electron containing orbitals. The outer electrons are away from experiencing the inward attractive pull of the nucleus (nuclear charge) and capable of undergoing electron-cloud distortion or polarization.
Mass Number
The mass number is the total count of the number of protons and neutrons present in the nucleus of an atom, denoted as A.
For example, 12C has 6 protons and 6 neutrons; its mass number is 12.
A mass number is always a whole number. The mass number is also known as the atomic mass number or nucleon number.

What factors affect the metallic bond strength?
A metal atom is large, so the nucleus cannot attract and hold its outermost electrons. The metal loses those electrons and becomes positively charged kernels. The electrons then flow in the solid structure passing between these positive kernels.
