A similarity between the forces involved in both ionic and covalent bonding is that both A. involve the sharing of electrons. B.
NISA [10]

Answer:

C. involve the attraction of opposite charges

Explanation:

<em>Ionic bonding</em> involves the attraction between <em>oppositely charged ions</em>, as in Na⁺ Cl⁻.

<em>Covalent bonding</em> involves the attraction between <em>negatively charged electrons and positivey charged nuclei</em>, as in a C-H bond.

A is <em>wrong</em>. Ionic bonding involves the transfer of electrons.

B is <em>wrong</em>. Covalent bonding involves the sharing of electrons.

D is <em>wrong</em>. Ionic bonds are usually stronger than covalent bonds.

Why is there such a large jump and ionization energy between the second and third ionization energy‘s for magnesium?
Romashka [77]
The second ionization energy of Mg is larger than the first because it always takes more energy to remove an electron from a positively charged ion than from a neutral atom. The third ionization energy of magnesium is enormous, however, because the Mg2+ ion has a filled-shell electron configuration.
