This is from the priciples of quantum chemistry:
A boron atom has three electrons in its second energy level.
An atom with seven electrons will have five electrons in the second energy level.
An argon atom has 2 electrons in its first energy level, 8 electrons in its second energy level, and 8 electrons in its third energy level.
Electrons in the outermost energy level (valence electrons) have the highest energy level. These electrons are involved in the atom's chemical reactions and bonding with other atoms.
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.

Electrons in the outermost energy level (valence electrons) have the highest energy level. These electrons are involved in the atom's chemical reactions and bonding with other atoms.
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.
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.
An atom has multiple energy levels. When an atom has more electrons than it can fit into an energy level, then it puts them into the next higher 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.
valence electrons are the electrons in the outermost energy level
The highest energy level is called the "electronegativity".
valence shell.....yes yes yes haha good bye losers
In a neon atom, the first energy level or orbit can hold up to 2 electrons, the second energy level can hold up to 8 electrons, and the third energy level can hold up to 8 electrons. Therefore, a neon atom would have 2 electrons in the first energy level, 8 electrons in the second energy level, and 8 electrons in the third energy level, totaling 18 electrons.
