Want this question answered?
An atom of antimony in its ground state has 3 unpaired electrons.
A neutral bromine atom has 35 electrons.
bromine is bigger. bromine has an extra shell of electrons. bromine reacts less vigorously. bromine has a larger amount of protons, neutrons and electrons.
The total number of valence electrons in Boron's ground state is 2
32000000
5 valence electrons exist in bromine period, at ground state bromine has 3 valence electrons
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.
Br = 1s22s22p63s23p64s23d104p5 or shortened to [Ar] 4s23d104p5 and there are 35 electrons total.
* Ground state electron configuration:[Ar].3d10.4s2.4p6 so...4s and 4p
It is n=4 because Br is in the 4p valence shell.

The Bromine atom contains: 35 protons, 35 electrons, and 45 neutrons.
This is called the "ground state", all electrons occupy the orbitals of lowest energy available to them.
The number of protons determines the number of electrons in the ground state of the atom. However electrons can be subtracted or added when the atom is not in its ground state, creating ions.
