b. 8P+, 10no, 8e-

Explanation:

An isotope is a form of a chemical element whose atomic nucleus of an element contains a specific number of neutrons and protons. For example, the nucleus of a carbon atom contains 6 neutrons (no) and 6 protons (P+) and similarly in the nucleus of oxygen contains 8 neutrons and 8 protons. The number of neutron can varies in the nucleus of that element. Variation in neutrons form isotopes of the element. In nature, oxygen has three stable isotopes, ¹⁶O, ¹⁷O, and ¹⁸O, but ¹⁶O most abundant. The ¹⁸O isotope of oxygen contains 8 protons (P+), 8 electrons (e-) and 10 neutrons (no) instead of normal 8 neutrons.
