Is most of the bacteria on your body harmful?

No it is not, most bacteria is very helpful, it helps the body function and fight off diseases when the body is sick. Sometimes the good bacteria can't fight off the bad bacteria and will cause you to have to buy antibiotics. The antibiotics give the body a huge advantage at fighting off the disease and the body goes back to normal.

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

120,630,890

step-by-step explanation:

110+10=120,620+10=630,880+10=890
