Explanation:

Step1: Recall element - proton relationship

The number of protons is equal to the atomic number. For example, for 3 protons, atomic number is 3 which is Lithium (Li).

Step2: Identify element by symbol

For symbol Pb, the element is Lead.

Step3: Consider neutral atom electron - proton equality

In a neutral atom, number of electrons = number of protons. So for 16 electrons, it's Sulfur (16 protons).

Step4: Use atomic number to find element

For atomic number 22, it's Titanium. And so on for other atomic - number based questions.

Step5: Match symbol to element

For symbol Ag, it's Silver; for Cu it's Copper etc.

Step6: Identify element by average atomic mass

For average atomic mass of 79.904, it's Bromine.
