Helium has two valence electrons
there are 8 electrons in the valence shell of neon
there are 8 electrons in the valence shell of neon
Helium has 2 valence electrons.
Hydrogen and helium
the number of electrons found in the third shell of an helium atom are nill because its atomic number is 2
there are 8 electrons in the valence shell of neon

Valance electrons.
The groups, or families of elements have the same number of valance electrons and this information can be found at the top of the periodic table. For instance; 1A represents the alkali metals and they all have a valance number of 1. Then go from the left to the right and look at the top of the table. 8A represents the farthest left family of elements, from top to bottom, the Nobel gasses. They have a full valance shell of 8 electrons.
2 electrons in the only shell helium has.
Helium has 2 valence electrons.
Hydrogen and helium
In normal Helium(He) atom there are 2 electrons, 2protons and 2 neutrons.
the number of electrons found in the third shell of an helium atom are nill because its atomic number is 2
Valance electrons. When you get to core electrons the ionization energy is extremely high and found under plasma conditions.
Hydrogen and helium
The two common elements found in the sun are Hydrogen and Helium.
