Question

Covalent bonding involves the sharing of electron pairs between atoms. Ionic bonding involves the electrostatic attractions between oppositely charged ions. Ions are either cations ("cat-ions", positively charged ions) or anions ("an-ions", negatively charge ions). An atom is by definition a neutral species, what does that mean regarding the number of protons, neutrons and electrons that it possesses? If a cation is positively charged what does that mean regarding the number of protons, neutrons and electrons that it possesses? If an anion is negatively charged what does that mean regarding the number of protons, neutrons and electrons that it possesses? Information - Pauling Electronegativity Scale The Pauling electro negativity scale is used to describe

Explanation / Answer

1) In an atom, since it is neutral the number of protons is equal to number of electrons. Since neutrons are neutral nothing can be said about them.

2)In cations that is positively charged ions, the number of electrons is less than that of protons. Hence the positive charge is present.

3)In anions that is negatively charged ions, the number of electrons is more than that of protons. Hence the negative charge is present.
