Question

b. fill in the blanks

1. the atomic number tells the number of ______.
2. electrons are found ______ the nucleus.
3. atoms form ions to become ______.

Explanation:

1.

In atomic structure, the atomic number is defined as the number of protons (and also electrons in a neutral atom) in an atom's nucleus. So the blank is filled with protons (or protons and electrons in a neutral atom, but primarily protons).

Electrons are subatomic particles that orbit around the nucleus in electron clouds or shells. They are located outside the nucleus.

Atoms form ions (by gaining or losing electrons) to achieve a stable electron configuration, similar to that of a noble gas. So they become stable (or have a stable electron configuration).

Answer:

protons (or protons and electrons for a neutral atom)
