Explanation:
Answer:
shells 1, 2 and 3 are full and shell 4 has one electron
Explanation:
The distribution fo the electrons possessed by an atom in the shells surrounding it is termed as its electronic configuration.
According to the rules of writing the electronic configuration:
1. The first shell can be occupied by a maximum of two electrons.
2. the subsequent shells can be occupied by a maximum of 8 electrons.
3. the subsequent shells are filled only once the lower shells have been filled.
Based on these rules, the electronic configuration of potassium should be 2, 8, 8, 1. (2+8+8+1 = 19).
Thus, we can see that the first three shells are filled, and the last one has one electron left.
If by inadequate you mean not meeting the necessary levels (too low), then it is "hypo"

Answer:
It has no atmosphere.
Its surface is covered with circular craters.
It has huge, round basins.
It has lunar highlands.
Explanation:
Mercury is similar to the moon because both have no atmosphere, surface is covered with circular craters and having large, round basins. Both have lunar highlands. Craters are the circular, excavated holes made by impact events that has a rough surface while on the other hands, most of the crust of the Moon is made of silicate rocks is known as anorthosites, these regions are called the lunar highlands.
