A bromine atom, regardless of its mass number, has an atomic number of 35, which means it has 35 protons and, in a neutral state, also 35 electrons. Therefore, a bromine atom with a mass number of 87 will have 35 electrons. The mass number indicates the total number of protons and neutrons, but it does not affect the number of electrons in a neutral atom.

How many electrons are present in a bromine atom with a mass number of 87?

A bromine atom with a mass number of 87 has 35 protons (since bromine has an atomic number of 35). Since it is neutral, it also has 35 electrons.


How many core electrons are in a ground state atom of bromine?

A ground state atom of bromine has 28 core electrons. This can be determined by subtracting the number of valence electrons in a neutral bromine atom (7) from the total number of electrons in a bromine atom (35).


What is the charge on a bromine atom that contains 36e?

A bromine atom with 36 electrons is neutral, as the number of protons (which is equal to the atomic number, 35 for bromine) is balanced by the number of electrons. The charge on a neutral bromine atom is 0.


What is the number of electrons in bromine-82?

Bromine-82 has 36 electrons since bromine has an atomic number of 35, which corresponds to the number of electrons in a neutral atom. The number of electrons remains the same in different isotopes of an element.


How many inner electrons does Br have?

Bromine (Br) has 36 inner electrons. This can be calculated by subtracting the number of valence electrons (7) from the total number of electrons in the neutral atom of bromine (usually 43).


How many core electrons does Br have?

Bromine (Br) has 18 core electrons. This can be determined by subtracting the number of valence electrons (7 in the case of bromine) from the total number of electrons in a neutral atom, which is 35 for bromine.
