If an atom loses and electron what type of ion does it form?

Answer

cation

Explanation:

If an atom losses electrons it forms a positively charged ion called the cation.

cation has more protons than electrons, thereby giving it a net positive charge.

To form a cation one or more electrons must be lost, typically pulled away by atoms with a stronger affinity for them.

The number of electrons lost, and so the charge of the ion, is indicated after the chemical symbol, e.g. zinc (Zn) loses two electrons to become Zn2+.

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.
