The second quantum number (l) for the electrons in the 4 p energy sublevel of bromine would be 1.
Bromine isotopes have different mass numbers because their atoms have different numbers of neutrons.
l = 1
All four quantum numbers i.e principle ,azimuthal or subsidiary, magnetic and spin quantum numbers are required to specify a single atomic orbital.
M1 = -1
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.
The second quantum number (l) for the electrons in the 4 p energy sublevel of bromine would be 1.
What are the quantum numbers of Br?
It is n=4 because Br is in the 4p valence shell.
Bromine isotopes have different mass numbers because their atoms have different numbers of neutrons.
from Max Planck's theory, quantum numbers are units of energy.
l = 1
There are 4 quantum numbers that specify the quantum system. n is the energy level, l is the angular momentum, ml is the projection of angular momentum, ms is the spin projection.
4f
Two natural isotopes of bromine are known:- bromine-79: 50,69 %- bromine-81: 49,31 %
All four quantum numbers i.e principle ,azimuthal or subsidiary, magnetic and spin quantum numbers are required to specify a single atomic orbital.
Bromine is bromine no matter how toxic
