The "up" and "down" arrows in electron orbital notation, such as are shown here, depict:
A. protons and neutrons in orbitals
B. electrons with opposite spins
C. electrons and protons attracting each other
D. oppositely charged electrons

The up and down arrows in electron orbital notation such as are shown here depict A protons and neutrons in orbitals B electrons with opposite spins C electron class=

Respuesta :

The answer to this question would be: B. electrons with opposite spins 

Proton and neutron located in the middle of the atom called nucleus. They are not located in orbit like electrons. So the option A and C will out since there is no way this diagram involving the protons. 
The electron has a negative charge and there are no such as oppositely charged electrons. The diagram is actually telling about the orbit of the electron. Electron will be paired with other electrons that will go in opposite spin
