There are 31 protons in gallium. For more detail about gallium, see the link below.
There are two stable isotopes of gallium: gallium-69 and gallium-71. Additionally, there are several radioactive isotopes of gallium, but they are unstable and decay over time.
Gallium is a mono-atomic metal element. So their atoms are atoms, and as many as you have!
Gallium is a non metal element. There are 31 electrons in a single atom.
Gallium is a chemical element. One might say it has one element.
Gallium-67 decays 100% of the time via electron capture, a process where a proton "captures" an electron forming a neutron and a neutrino, so therefore the decay product will have the same same atomic mass number, but an atomic number lowered by one. So for gallium-67, that yields zinc-67.

For example, gallium arsenide (GaAs) is used from many years in laser diodes.
Gallium is malleable.It has a hardness of only 1.5 on Mohs scale.Is_gallium_malleable
One formula unit of gallium oxide (Ga2O3) contains a total of 5 atoms - 2 gallium atoms and 3 oxygen atoms.
moles = 245g / atomic weight of gallium = 245 / 69.72 = 3.51 moles

Ga3+ has 31 - 3 = 28 electrons
