An atom in which the outermost energy level is more than half full tends to fill its outermost energy level by adding one or more needed electrons. Such an atom forms a negative ion.
valence electrons are the electrons in the outermost energy level
The outermost principle energy level for strontium is the 5th energy level.
Helium only needs two electrons to have a filled outermost energy level.
Valence electrons are found in the outermost energy level of an atom, also known as the highest principal energy level. These are the electrons involved in chemical bonding and determining the reactivity of an element.

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.
A neutral atom of magnesium has 2 electrons in its outermost energy level. Magnesium has a total of 12 electrons, with 2 electrons in the first energy level and 8 electrons in the second energy level. The outermost energy level is the second energy level in the case of magnesium.
Outermost energy level is full if there are 8 electrons in the valence shell.
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.
Sulfur has 6 electrons in its outermost energy level.

Fluorine has 7 electrons in its outermost energy level. Its electron configuration is 2-7, with 7 electrons in the outermost energy level, making it highly reactive.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
A neutral sulfur atom has 6 electrons in its outermost energy level. Sulfur has 16 electrons, with 2 electrons in the first energy level, 8 electrons in the second energy level, and 6 electrons in the third and outermost energy level.
