Question

why are the isotopes of an element chemically similar?Three atom of oxygen are re-presented as 16/8 O, 17/8 O, 18/8 O
​

Answer 1

Explanation:

For example, there are three isotopes of the element oxygen (O): Oxygen 16, 17, and 18. Each isotope of oxygen contains 8 protons, but differs in the number of neutrons. ... Therefore, oxygen 16 has 8 protons and 8 neutrons, oxygen 17 has 8 protons and 9 neutrons, and oxygen 18 has 8 protons and 10 neutrons.
