The principal quantum number for the outermost electrons in a Bromine atom in the ground state is?

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.


How many valence shell of Bromine have?

Bromine has four valence shell electrons. It is located in Group 17 of the periodic table, which means it has seven electrons in its outermost shell (the fourth energy level). Therefore, Bromine has four energy levels, with the outermost shell containing the valence electrons necessary for chemical bonding.


What is the principal quantum number for the outermost electrons in a bromine atom in the ground state?

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.


How many electrons are in the outermost energy level of carbon and how many does it need to have this energy level filled?

Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.

How many electrons will a neutral sulfur atom have 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.


Explain how valence electrons in an atom are used to form a full 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.


How many electrons of a neutral atom of magnesium are 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.
