If the spin of one electron in an orbital is clockwise, what is the spin of the other electron in that orbital?
umka2103 [35]

Answer:

The other electron must have anticlockwise spin.

Explanation:

According to the pauli exclusion principle, the two elecrton present in same orbital must have opposite spin.

If the one electron is clockwise the other must be in anti clockwise direction. The clockwise direction is represented by the sign +1/2 while anti clockwise direction is represented by -1/2.

According the pauli principle, the two electrons must have different fourth electronic quantum number. The electron in same orbital have same first three quantum number i.e, n=1 l=0 and ml =0 in case of first subshell.

The lab coat is not thick enough to protect you from ionizing radiation.

<h3>What is radiation?</h3>

Radiation is a form of energy that we can not see with our optical eyes. We know that radiation could have a damaging effect on the body. The sort of radiation that could have a damaging effect on the body is what we call ionizing radiation.

We know that an ionizing radiation could only be stopped by a thick vest such as a lead coat. If you are wearing a lab coat, you are not safe because the lab cat is not thick enough to protect you from ionizing radiation.
