Answer

Explanation:

Step1: Recall atomic number concept

The atomic number represents the number of protons in an atom. It also equals the number of electrons in a neutral atom.

Step2: Recall atomic mass concept

The atomic mass is the sum of the number of protons and neutrons in an atom.

Step3: Determine number of protons/electrons

The number of protons or electrons in an atom is equal to the atomic number of the element.

Step4: Determine number of neutrons

The number of neutrons in an atom is calculated as: Atomic Mass - Atomic Number.

Answer:

  1. Symbol: O, Element Name: Oxygen, Atomic Mass: 15.999
  2. The atomic number represents the number of protons (or electrons in a neutral atom).
  3. The atomic mass represents the sum of protons and neutrons.
  4. The number of protons or electrons is equal to the atomic number.
  5. The number of neutrons = Atomic Mass - Atomic Number.
