Answer

Explanation:

Step1: Recall atomic number concept

The atomic number is equal to the number of protons. Each proton has a charge of + 1 and each electron has a charge of - 1.

Step2: Analyze 16 - proton case

The element with 16 protons is sulfur (S). The number of electrons is 18. The charge is calculated as (16\times( + 1)+18\times(-1)=16 - 18=-2).

Step3: Analyze 35 - proton case

The element with 35 protons is bromine (Br). The number of electrons is 36. The charge is calculated as (35\times( + 1)+36\times(-1)=35 - 36=-1).

Determine neutral atom/ion

  • For 7 protons and 10 electrons: Since the number of protons ((p = 7)) and electrons ((e = 10)), (p\neq e), it is an ion.
  • For 15 protons and 15 electrons: Since (p = 15) and (e = 15), (p = e), it is a neutral atom.
  • For 35 protons and 37 electrons: Since (p = 35) and (e = 37), (p\neq e), it is an ion.

Answer:
