Answer:
<h3>A. </h3>
Explanation:
Mechanical energy is energy in motion is the example of mechanical energy⚡
It is a Covalent bond because the electrons are shared between the two individual atoms. (Hydrogen is complete at 2 electrons)
The first orbital will have 2 electrons, and the other two will have only 1 electron. So, strat filling each orbital with 1 electron, and when they each get one, then start over, so for 4 electrons, the first one will have 2 electrons in the orbital.
An example of a base in chemistry would be like soap or lye
