The electron configuration of helium is 1s2; two electrons on the first (and the single) electron shell.
Helium has only one electron shell with two electrons.
Helium atom has 2 electrons.
Helium has only 1 shell with two electrons.
Helium will have only 2 electrons
There are no electrons present in a helium atom in its second energy level.
Helium has two valence electrons
Helium atom has 2 electrons.
Helium has only 1 shell with two electrons.
2
helium has 2 electrons as its atomic number is 2
Helium will have only 2 electrons
Helium has two valence electrons
Helium is a non metal element. There are 2 electrons in a single atom.
There are no electrons present in a helium atom in its second energy level.
Helium has 2 valence electrons.
Helium has only 1 shell with two electrons.
2. The atomic number which is 2 stands for how many protons (also electrons, in an uncharged atom) are in the element's atom.
atoms try to get 10 electrons on shells around the atom. how many shells the atom has is based on the atomic number and atomic mass the atomic number determines how many shells their are.
