When aluminum atom loses its valence electron, what is the charge on the resulting
ion?

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.

no but i do not usually comment or use my voice that much when it comes to social media

increased stability in the completion of fluorine's outer shell.

what is the question?
