Sc is a 3d element. It has 21 protons and 21 electrons.
Neutrons: 6 Protons: 6 Electrons:6
A helium atom has 2 protons, 2 neutrons, and 2 electrons.
The normal helium atom has two protons and two neutrons in the nucleus, and two electrons in the "shell".
One Proton One electron zero neutrons
since there are 22 protons there has to be 22 nuetrons since there are 22 protons there has to be 22 nuetrons
protons and nuetrons are equal to no. of electrons present in atom
19 protons,21 neutrons
26 nuetrons, 22 electrons, and 22 protons
there are 12 protons in an atom of magnesium:-)
hey perhaps your question is incomplete. but if your question is what is protons and neutron relationship then a neutron plus a positive charge having mass equal to electron mass then proton forms.
2 of each
5 protons 8 neutrons try it
Oxygen has: 8 neutrons 8 protons (8 electrons)

20 protons, 20 electrons, and usually 20 neutrons
