Helium has two protons and two neutrons (and two electrons).
Chlorine has 18 neutrons.
The chemical element of chlorine has 18 nuetrons,17 protons and 17 electrons
To find the number of moles of helium in the balloon, you need to divide the mass of helium by its molar mass. The molar mass of helium is approximately 4 g/mol. Therefore, 0.46 g of helium is equal to 0.46 g / 4 g/mol = 0.115 mol of helium in the balloon.
mass number = protons + nuetrons
The symbol of Helium is He. Helium's atomic number is 2.
2 of each
There are 2 neutrons in a helium atoms nucleus , along with two protons.
1 neutron in He-3 isotope. 2 neutrons in He-4 isotope (most stable)
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".
Nothing. Helium is an element so it is as is. Or if you were looking for something else it would be what it is made of, which would be protons (p+) nuetrons (n0) and electrons (e-)
since there are 22 protons there has to be 22 nuetrons since there are 22 protons there has to be 22 nuetrons
there are 12 nuetrons in an atom of magnesium
im eleven and i know the answer the answer is 18 nuetrons
protons and nuetrons are equal to no. of electrons present in atom
26 nuetrons, 22 electrons, and 22 protons
