Indicate the number of protons, neutrons and electrons in the oxygen atom. Draw a diagram of the structure of the oxygen atom.

The oxygen atom in the periodic system of D.I. Mendeleev is located in the second period, group VI A. The ordinal number of oxygen is 8. The number of electrons is equal to the number of protons, equal to the ordinal number of a chemical element. The number of neutrons is determined by the formula N = A-Z. A is the atomic mass of a chemical element, Z is the charge of the atomic nucleus, the number of neutrons N = 16 – 8 = 8
