Explanation:

Step1: Recall element - proton/electron/atomic number relationship

The number of protons in an atom is equal to its atomic number. In a neutral atom, the number of electrons is equal to the number of protons. We use the periodic table to find elements based on these properties and symbols.

Step2: Answer question 1

The element with 3 protons has an atomic number of 3. From the periodic table, it is Lithium, symbol Li.

Step3: Answer question 2

The element with 12 protons has an atomic number of 12. It is Magnesium, symbol Mg.

Step4: Answer question 3

The element with symbol Pb is Lead.

Step5: Answer question 4

A neutral atom has equal number of protons and electrons. An element with 16 electrons has 16 protons and atomic number 16, which is Sulfur, symbol S.

Step6: Answer question 5

The element with atomic number 22 is Titanium, symbol Ti.

Step7: Answer question 6

The element with atomic number 40 is Zirconium, symbol Zr.

Step8: Answer question 7

The smallest element on the periodic table in terms of atomic number is Hydrogen, symbol H.

Step9: Answer question 8

A neutral atom with 26 electrons has 26 protons and atomic number 26, which is Iron, symbol Fe.

Step10: Answer question 9

The element with symbol Ag is Silver.

Step11: Answer question 10

The element with an average atomic mass of approximately 79.904 is Bromine, symbol Br.

Step12: Answer question 11

The element with atomic number 94 is Plutonium, symbol Pu.

Step13: Answer question 12

The element with symbol Cu is Copper.

Step14: Answer question 13

The element with 14 protons has an atomic number of 14, which is Silicon, symbol Si.

Step15: Answer question 14

A neutral atom with 3 electrons has 3 protons and atomic number 3, which is Lithium, symbol Li.

Step16: Answer question 15

The element with symbol N is Nitrogen.

Step17: Answer question 16

The element with symbol K is Potassium.

Step18: Answer question 17

The element with symbol Fe is Iron.

Step19: Answer question 18

The element with atomic number 80 is Mercury, symbol Hg.

Step20: Answer question 19

The element with symbol Na is Sodium.
