Question

what is the difference between a bromine atom and a bromine ion? a bromine atom has 35 electrons, while a bromine ion has 34 electrons. a bromine atom has 35 protons, while a bromine ion has 36 protons. a bromine atom has 35 protons, while a bromine ion has 34 protons. a bromine atom has 35 electrons, while a bromine ion has 36 electrons.

Explanation:

• The atomic number of bromine is 35, which means both bromine atom and bromine ion have 35 protons. So options with different number of protons for atom and ion are wrong.
• A bromine atom is neutral, so it has 35 electrons (equal to the number of protons). A bromide ion (\(Br^-\)) gains one electron, so it has \(35 + 1=36\) electrons.

Answer:

A bromine atom has 35 electrons, while a bromine ion has 36 electrons.
