Question

What is the meaning of o to power - 2 how many electron and proton.

Answer 1

Answer:

2 electrons with negative charge..it also means oxidation number is 2

Answer 2

Answer:

In physics, power is the rate of doing work or of transferring heat, i.e. the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. ... But more power is needed when the work is done in a

.

This means that the negative charge on an electron perfectly balances the positive charge on the proton. In other words, a neutral atom must have exactly one electron for every proton. If a neutral atom has 1 proton, it must have 1 electron. If a neutral atom has 2 protons, it must have 2 electrons.
