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.
