Explanation:

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

The number of protons is equal to the atomic number and in a neutral atom, the number of electrons is equal to the number of protons. Use the periodic table to identify elements based on these properties and symbols.

Step2: Identify element with 1 proton

Hydrogen (H) has 1 proton.

Step3: Identify element with 17 protons

Chlorine (Cl) has 17 protons.

Step4: Identify element with symbol Pb

Lead has the symbol Pb.

Step5: Identify element with 16 electrons

In a neutral atom, number of electrons = number of protons. Sulfur (S) has 16 protons and 16 electrons.

Step6: Identify element with atomic number 27

Cobalt (Co) has atomic number 27.

Step7: Identify element with atomic number 40

Zirconium (Zr) has atomic number 40.

Step8: Identify the smallest element on the periodic table

Hydrogen (H) is the smallest element on the periodic table in terms of atomic size and atomic number.

Step9: Identify element with 26 electrons

In a neutral atom, with 26 electrons, there are 26 protons. Iron (Fe) has 26 protons.

Step10: Identify element with symbol Ag

Silver has the symbol Ag.

Step11: Identify element with average atomic mass of 79.904

Bromine (Br) has an average atomic mass of approximately 79.904.

Step12: Identify element with atomic number 94

Plutonium (Pu) has atomic number 94.

Step13: Identify element with symbol Cu

Copper has the symbol Cu.

Step14: Identify element with 14 protons

Silicon (Si) has 14 protons.

Step15: Identify element with 3 electrons

In a neutral atom, with 3 electrons, there are 3 protons. Lithium (Li) has 3 protons.

Step16: Identify element with symbol N

Nitrogen has the symbol N.

Step17: Identify element with symbol K

Potassium has the symbol K.

Step18: Identify element with symbol Fe

Iron has the symbol Fe.

Step19: Identify element with atomic number 80

Mercury (Hg) has atomic number 80.

Step20: Identify element with symbol Na

Sodium has the symbol Na.

Step21: Identify element with 40 protons

Zirconium (Zr) has 40 protons.
