an atom of gallium has 31 proton and a mass number of 70 what is the atomic number for an atom of gallium
padilas [110]

Hello!

Atomic Number, is the number where the atom lays on the perodic table and can be found through the number of protons. Meaning that gallium has an atomic number of 31 !

Atomic weight, which is equal to 70 in this case, can be found by subtracting the atomic number from that total to find the remaining number of neutrons that make up the mass. So gallium has 31 protons and 39 protons.


Hope this helps answer your question.
