This atom is helium. Helium has two protons, two neutrons, and two electrons. It has the atomic number of 2 on the periodic table.
Helium has a full outermost energy level containing only two electrons.
Helium (He)
Since its only the high-energy electrons that participate in a ... Two different elements have similar chemical properties when they have the same number of valence electrons in their outermost energy level.
The electrons in the outermost level are known as the valence electrons.
valence electrons are the electrons in the outermost energy level
Halogens have six valence electrons in the outermost energy level.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Aluminum has 3 electrons in its outermost energy level.
Carbon has 4 outermost electrons.
Sulfur has 6 electrons in its outermost energy level.
Atoms form chemical bonds to achieve a full outermost energy level by sharing, gaining, or losing electrons. Valence electrons are the electrons in the outermost energy level of an atom, and having a full outermost energy level makes the atom more stable. This stability is achieved when there are eight electrons in the outermost energy level, known as the octet rule.
they are referred as valence electrons. These are the electrons in outermost shell.
