Ok here we go;
The atomic number of Mercury(Hg) is 80; since atomic number of an atom= No. of protons.Thus No. of protons in Mercury is 80.
Also No. of protons = No. of electrons (In an neutral Atom; which is not an ion).Therefore No. of electrons is also 80.
Next, Mass number(Atomic Mass) of Mercury is 160.
Mass Number(Atomic Mass)= No. of Protons + No. of Neutrons.
Hence calculating that we get No. of Neutrons also to be 80.
FYI; Electrons have negligible mass so they are not included in calculating Mass of an atom, which only requires the nucleus which contains only protons and neutrons.

2 protons + 2 neutrons= atomic number of 4. I haven't memorized all of the elements but just go to any periodic table and see which one is associated with an atomic number of 4

there are 80 protons and probably 80 electrons and there are 121 neutral for murcury's atom

In all atoms, P = e In your case you have specified the nucleus of a helium atom and the electron shell of carbon.
