Helium (He).
The correct nuclear symbol for an isotope with 80 protons and 124 neutrons is Xe-204, where Xe represents the element xenon.
The nuclear symbol would be ^44Ti, representing the element titanium, since the atomic number (number of protons) is 22 (20 electrons + 2 protons) and the mass number (protons + neutrons) is 44 (22 protons + 24 neutrons).

If you remove 2 protons and 2 neutrons from gold (Au), the resulting element would be platinum (Pt). Gold has 79 protons and 118 neutrons, while platinum has 77 protons and 116 neutrons.

They are both Isotopes of Barium. The 56 protons tell us that the element is Barium and when you add the neutrons with the protons you get barium138 and barium134. They are both stable isotobes of barium but of all the barium in the world about 72% is barium138 and 2% is barium134.
It is normal for the isotope of the element helium. 2He4 isotope has 2 protons, 2 neutrons and 2 electrons.
Yes. He-4 isotope has 2 protons, 2 electrons and 2 neutrons
Helium has 2 protons, 2 neutrons, and 2 electrons.
An alpha particle has 2 protons and 2 neutrons. That is the same as a helium nucleus.
There is no such element: an element is neutral, so it has equal numbers of protons and electrons.Impossible:2 protons 4 neutrons and 3 electrons is the IMpossible He-1 isotope with mass number 6 (=2p+4n). Helium does not accept electrons because it is noble.Possible:2 protons 4 neutrons and 2 electrons is (elemental) Helium, isotope with mass number 6 (=2p+4n)3 protons 4 neutrons and 3 electrons is (elemental) Lithium
Each chemical element has a different number of protons; the number of neutrons can be similar.
