7, since bromine is a halogen
The principal quantum number for the outermost electrons in a Bromine atom in the ground state is 4. This is because the outermost electrons of an atom are located in the highest energy level, and for Bromine (with 35 electrons), the outermost electrons are in the 4th energy level.
The electronic configuration of Bromine in its ground state is: 1s2 2s2p6 3s2p6d10 4s2p5. Therefore the principal quantum number for the outermost electrons in a Bromine atom is 4.
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.
5 valence electrons exist in bromine period, at ground state bromine has 3 valence electrons
The chloride ion (Cl-) has 8 electrons on 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.
valence electrons are the electrons in the outermost energy level
Halogens have six valence electrons in the outermost energy level.
Sulfur has 6 electrons in its outermost energy level.
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.
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.
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.
5 valence electrons exist in bromine period, at ground state bromine has 3 valence electrons
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.
