Explanation:

Step1: Identify atomic number

The top - left number in an element's box in the periodic table is the atomic number. Here, it is 30.

Step2: Define atomic mass

The bottom number is the atomic mass. So, the atomic mass of zinc is 65.39.

Step3: Determine number of protons

The number of protons is equal to the atomic number. So, the number of protons is 30.

Step4: Calculate number of neutrons

The number of neutrons is approximately the atomic mass rounded to the nearest whole number minus the number of protons. Rounding 65.39 to 65, then 65 - 30=35.

Step5: Determine number of electrons

In a neutral atom, the number of electrons is equal to the number of protons. So, the number of electrons is 30.

Answer:

ATOMIC #: 30
ATOMIC MASS: 65.39

OF PROTONS: 30

OF NEUTRONS: 35

OF ELECTRONS: 30
