16. in which of these cases do we have enough information to say that the atom is electrically neutral? a. the atom has 15 neutrons and 15 electrons. b. the atom has 4 neutrons and 4 protons. c. the atom has 19 electrons and 19 neutrons. d. the atom has 7 protons and 7 electrons.

Option (D) is the correct answer.

Explanation:

An atom will be electrically neutral when the number of protons equal the number of electrons.

For example, atomic number of fluorine is 9 this means that there are 9 protons in a fluorine atom. Also, there are 9 electrons in fluorine atom. So, fluorine will be neutral.

Thus, we can conclude that out of the given cases we can say that the atom has 7 protons and 7 electrons have enough information to say that the atom is electrically neutral.
