Explanation:

Step1: Count protons in nucleus

Protons are the positively - charged particles in the nucleus. For atom A, count the number of particles in the nucleus with a positive charge (usually represented by a different symbol or color in diagrams).

Step2: Count neutrons in nucleus

Neutrons are neutral particles in the nucleus. Count the number of non - charged particles in the nucleus of atom A.

Step3: Determine number of electrons

In a neutral atom, the number of electrons is equal to the number of protons. So, the number of electrons in atom A is the same as the number of protons.

Step4: Calculate atomic mass

Atomic mass is the sum of protons and neutrons in the nucleus. So, atomic mass of atom A = number of protons + number of neutrons.

Step5: Determine atomic number

The atomic number is equal to the number of protons in an atom. So, the atomic number of atom A is the number of protons.

Since we don't have the actual diagram details to perform the counts:

Answer:

1. <Number of protons in atom A>
2. <Number of neutrons in atom A>
3. <Number of electrons in atom A (equal to number of protons if neutral)>
4. <Sum of protons and neutrons in atom A>
5. <Number of protons in atom A>

(Repeat the above process for atom B in a similar fashion once the actual diagram details are known)
