Write the representation of
Chlorine with number of
electrons, protons and neutrons
are 18, 17 and 20.​

Answer 1

Answer:

An element with 17 protons will always be chlorine. However an element's mass numbers can vary, which means that it can have different numbers of neutrons. So although chlorine has a mass number of 35 which means it has 18 neutrons, it can also have a mass number of 37, which means it has 20 neutrons.
