Detailed explanation-1: -Consider oxygen, which has an atomic number (Z) of 8. This means that oxygen atoms have 8 protons. Most atoms of oxygen also have 8 neutrons. Oxygen atoms with 8 neutrons would have a mass number of 16 (8 p+ + 8 n0), meaning they would have a mass of about 16 amu.
Detailed explanation-2: -Oxygen atom has 8 electrons, 8 protons and 8 neutrons.
Detailed explanation-3: -Answer and Explanation: For oxygen, it has an atomic number of 8. This means that there are 8 protons in the nucleus of the atom. With a mass number of 16, this means that the sum of protons and neutrons is 16.
Detailed explanation-4: -Answer: atomic number=8. atomic mass=16. Name that element=oxygen.
Detailed explanation-5: -Oxygen-16 (16O) is a stable isotope of oxygen, having 8 neutrons and 8 protons in its nucleus.
