Explanation:

Since the problem involves analyzing molecular structures, atom counts, and chemical bonding (implied by questions about what holds atoms together), the relevant subfield is Chemistry (under Natural Science). However, as the user hasn't specified a particular sub - question to solve, here's a general approach for a sub - question like 1b (How many atoms are in a molecule of RSq?):

Step - by - Step Format (for a typical molecular structure analysis question like 1b)

Step 1: Identify the atoms in RSq

Assume from the molecular formula notation (similar to chemical formulas) that R, S, and q are different atoms (in a typical chemistry context, this notation is analogous to elements like H, O, C etc.). The formula RSq suggests one R atom, one S atom, and one q atom.

Step 2: Sum the number of atoms

To find the total number of atoms, we add the number of each type of atom. So, the number of R atoms is 1, S atoms is 1, and q atoms is 1. The total number of atoms $= 1 + 1+ 1=3$.

Answer:

For the sub - question 1b (assuming the above analysis), the number of atoms in a molecule of RSq is 3.

(Note: For other sub - questions, the approach would vary. For example, for question 4, the answer would be "A chemical bond (such as a covalent bond) is holding the atoms together" with a brief explanation about how atoms in a molecule are bonded. For question 5a, the answer is "Yes, a particle can be a single atom. For example, noble gas atoms like helium (He) exist as single atoms and are particles in a gas sample." with an appropriate explanation.)
