Answer:
b) N3-
Explanation:
The octet rule stipulates that a chemical specie is stable if it has eight electrons in its outermost shell.
Nitrogen belongs to group 15. This means that it has five electrons in its outermost shell. The formation N3- means that it accepted three electrons.
This brings the total number of outermost electrons to eight in accordance with the octet rule.
<span>Every atom and molecule has its own chemical potential energy value since atoms and molecules are attracted to each other. Whenever atoms and molecules form ionic or covalent bonds, their individual potential energies are converted into heat or light energy. The heat or light energy is released as the bonds form. Atoms that form strong bonds have lower potential chemical energy levels and release little heat or light, while atoms that form weak bonds have higher potential chemical energy levels and release a lot of heat or light during the formation of chemical bonds.

Pressures simply add. If the partial pressure of gas is three and the partial pressure of water is five, the total pressure is eight. Find the partial pressure for water at the temperature of your experiment, subtract it from your <span>pressure reading.</span>
Correct answer- B the electrons every two elements are arranged in energy levels: a maximum two electrons in the first level. ((( i thinkkk )))
