A bromine atom has seven electrons in its outermost shell.
Two. An inner shell contains 2 electrons; and an outer shell contains 2 electrons on its near side and 4 more electrons on its outer side. Total of 8 electrons.
The innermost shell of any atom bigger than hydrogen (H) will contain 2 electrons.
The very inner shell of an atom is the 1st shell and can only contain 2 electrons.
there are 2 electrons in the inner shell of a hydrogen atom.
Valence electrons are the electrons in the outermost shell of an atom. The ones in the inner shell are known as core electrons.
Selenium needs two more electrons.
Valence electrons are the electrons in the outermost shell of an atom. The ones in the inner shell are known as core electrons.

The negative charge of electrons in the inner shell(s) of the atom.
A bromine atom has seven electrons in its outermost shell.
two
There are 3 shells total in the atom of Chlorine. The first shell has 2 electrons because the first shell of any atom can only hold up to a maximum of 2 electrons. The second shell holds 8 electrons because the second shell of any atom can only hold 8 electrons maximum. The third shell holds 7 electrons in the Chlorine atom, but the third shell of any atom can hold up to 18 electrons as a maximum.
A free electron is able to move as it is in the outer shell of the atom. So free electrons can carry a charge. If an atom has free electrons it is able to conduct electricity. Inner shell electrons cannot carry a charge as they are closer to the nucleus.
Valence electrons are the electrons in the outermost shell of an atom. The ones in the inner shell are known as core electrons.
