Bromine has 35 electrons in its neutral state, and, as it is a halogen, 36 in its most stable ion. So it would have 4 shells, with 2, 8, 18, and 7 electrons in the neutral state, or 2, 8 ,18 and 8 electrons in its stable ion.
The Noble Gases are so-called because they do not readily react chemically with anything, due to their valence electron shells being filled with 8 electrons. The exception, of course, is helium, He, which only has 2.
Gallium is a mono-atomic metal element. So their atoms are atoms, and as many as you have!

Halogen molecules, such as chlorine (Cl2), bromine (Br2), and iodine (I2), are composed of two atoms each. This is because halogens belong to Group 17 of the periodic table, which means they have 7 valence electrons and need to gain one more electron to reach a stable octet configuration. Two atoms of a halogen molecule share electrons to achieve this stable configuration.
Halogen family members, or elements in group 17, have 7 valence electrons.

Halogens are group 17 elements. They have 7 valence electrons.
This atom become an anion with negative charge -1.
Halogens each have 7 valence electrons.
7 electrons are on the outer (valence) shells of all halogens

Carbon atoms have 6 electrons, when non-ionized

yes these do have electrons in them.While protons have a positive (+) .Electrons have a negative (-) charge.And neutrons have no charge at all. usually atoms have the same number of electrons and protons making them devoid.Salt and pepper react to electricity but not sugar.
