Ans: 4) Sulfur

In general for a given element:

The atomic number (Z) = number of protons

The atomic mass (A) = number of protons + number of neutrons

Atomic number Z of Neon, Ne = 10

Atomic number Z of oxygen, O = 8

Atomic number Z of sodium, Na = 11

Atomic number Z of sulfur, S = 16

Hence, sulfur is the element with 16 protons.
