c. 27
d. 40

Explanation:

Q3 Solution:

Step1: Recall neutral atom electron-proton relation

In a neutral atom, the number of electrons equals the number of protons.

Step2: Identify proton number

The atom has 8 protons.

Step3: Determine electron number

So, the number of electrons in this neutral atom is also 8. Wait, but looking at the options (assuming the options are like A.6, B.8, C.7, D.14 from the blurred text), the correct one should match the proton number. Since protons = 8, electrons = 8.

Step1: Recall atomic number definition

Atomic number is the number of protons in an atom.

Step2: Identify proton number of aluminum

The aluminum isotope has 13 protons.

Step3: Determine atomic number

So, the atomic number is equal to the number of protons, which is 13.

Answer:

8 (assuming the option with 8 is correct, e.g., if options are A.6, B.8, C.7, D.14, then B. 8)
