Helium has 2 protons and 2 neutrons, so the answer is 4.
Helium is a non metal element. Atomic mass of it is 4.00.
It's just 4.002602 amu
Helium with an atomic mass of 4.00260
Approximately 4.01
Well, two times four is eight, which would be oxygen.
Helium is a non metal element. Atomic mass of it is 4.00.
It's just 4.002602 amu
Helium with an atomic mass of 4.00260
Helium is a non metal element. Atomic mass of it is 2.
4.002602 g/mol
Helium's atomic number is 2 and its atomic mass is 4
Approximately 4.01
Helium is a metal element. Atomic number of it is 2.
Well, two times four is eight, which would be oxygen.
Symbol: He atomic #: 2 atomic mass: 4.002602
Atomic mass = weight in gram / moles = 10 / 2.5 = 4 amu
