so I have this work I have to do and I have NO clue how to do it! I'm pretty sure its simple, I just don't get the concept yet. And if you could help me clear it up id be forever grateful (:
so I have to identify the following elements:
a. Atom A has 50 electrons- would this be Tin?
b. Atom B has a charge of 33+ on its nucleaus
c. Atom C has 123 neutrons and 80 electrons
d. Atom D has 28 protons and 31 neutrons
help? I have nooo clue how to figure them out and im really stuck and confused..
I think I got it now, except I still don't understand how to do B..?

a. Atom A has 50 electrons- would this be Tin? yes, with 50 electrons it also has 50 protons or atomic number 50
b. Atom B has a charge of 33+ on its nucleaus 33 protons = As
c. Atom C has 123 neutrons and 80 electrons 80 electrons =80 protons=Hg
d. Atom D has 28 protons and 31 neutrons 28 protons =Ni

Protons are the easiest way to figure out what an element is. The number of protons corresponds with the atomic number on a periodic table. A stable atom will have the same number of electrons as protons but if you see a + or - next to their charge, that indicates how many extra/required electrons the atom has. Finally, the number of protons plus neutrons is equal to the atomic mass. I hope this helped you!
