Answer:
4s2
Explanation:
The electronic configuration of zinc in the ground state of the atom is 1s22s22p6 3s23p63d104s2. It can be written in a condensed form by showing the inert gas core as follows; [Ar] 3d¹⁰ 4s².
Zinc has a pseudo inert gas configuration when the 4s electrons are removed during oxidation. Hence this sublevel is usually affected when zinc atoms are oxidized according to the scheme;
Zn---->Zn^2+ + 2e-

Answer:
Molarity is similar to Concentration
Explanation:
Molarity (M) is the amount of solute in a solvent, similar to concentration.
The sets of characteristics describe what we know about
the inner planets is that have rocky
surfaces, no rings, and few or no moons. The answer is letter C. Also, they are
smaller in sizes compared to the outer planets. The rest of the choices are
characteristics of the outer planets.
The motion causes day and night because the earth is constantly spinning on it's axis.
