For 1: The correct answer is Model 1, 2, and 4.
For 2: The correct answer is Option 1.
Explanation:
For 1:
An element has 3 subatomic particles: electrons (E), neutrons (N) and protons (P).
Atomic number is defined as the number of protons or number of electrons.
Atoms having same number of protons are same. From the given models, Model 1, 2 and 4 have 2 protons with different neutrons. Hence, these models belong to same element.
