In theory 2 but in practice this has never been found. Helium is extremely stable and holds on to its electrons and does not share or "lend" them.
Helium has 2 valence electrons.
There are particular isotopes that have similar number of electrons and neutrons. Some of these isotopes include hydrogen-2, helium-4, carbon-12 and nitrogen-14.
7 Helium contains two electrons in all naturally occurring states.
There are 2 electrons in level one of a helium atom.
A neutral atom of helium must possess two electrons. Each electron carries a negative charge of -1, and since helium has a charge of 0 (neutral), the number of electrons must equal the number of protons, which is 2 in the case of helium.
Helium is a non metal element. There are 2 electrons in a single atom.
Helium has 2 valence electrons.
Helium is a non metal element. There are 4 electrons in a single atom.
There are particular isotopes that have similar number of electrons and neutrons. Some of these isotopes include hydrogen-2, helium-4, carbon-12 and nitrogen-14.
2. The atomic number which is 2 stands for how many protons (also electrons, in an uncharged atom) are in the element's atom.
Helium has two valence electrons. It is the only noble gas not to have eight valence electrons. Helium has the electronic configuration 1s2.The Noble gases have eight valence electrons in their outer shell.
