Help with tenth grade chemistry PLEASE! Subatomic heavyweights

Heres the link to the workpage:

I'm on the first page and I don't understand what to do or what they're even asking me to do.

I'm going to try and walk you through this as best I can.

In this exercise, you are looking at ten boron atoms. Imagine that these 10 B atoms were taken at random from a sample of boron (which is a gray powder). You can tell that all the atoms shown on the picture are boron. How? The protons are the light colored circles in the nucleus (the pile in the middle of the atom). Notice that every atom on that page has 5 light circles = 5 protons. The number of protons in an atom (the atomic number) tells us what the name of the atom is. All atoms with 5 protons (see the periodic table) are boron (B) atoms. Just like all atoms with 6 protons are carbon (C) atoms.

Notice that there are also dark colored circles in the nucleus mixed in with the protons. These dark circles are the neutrons, which weigh the same as a proton, but they have no charge. Notice also that there are small circles outside the nucleus that are arranged in rings. These are the electrons that have a negative charge and are responsible for chemical reactions, but they have very little mass compared to the protons and neutrons, so little mass that we usually ignore them. In a regular atom like boron, the number of protons and electrons are the same.

Let's go through the worksheet and number the top row of atoms 1 through 5 and the second row of atoms 6 through 10. Now let's look at each atom and count the number of protons (p), neutrons (n), and electrons (e).

Atom 1: 5p, 5n, 5e
Atom 2: 5p, 6n, 5e
Atom 3: 5p, 6n, 5e
Atom 4: 5p, 6n, 5e
Atom 5: 5p, 5n, 5e
Atom 6: 5p, 5n, 5e
Atom 7: 5p, 6n, 5e
Atom 8: 5p, 6n, 5e
Atom 9: 5p, 6n, 5e
