The energy required to remove the third electron from an atom would be called the a. tertiary removal energy b. atoms cannot lose 3 electrons. c. teriary ionization energy d. third ionization energy

D. Third ionization energy

Explanation:

Ionization energy describes the energy enough to remove the valence electrons from atoms in a ground state. It is a measure of the readiness of an atom to lose an electron. The lower this value, the easier it is for an atom to lose electrons and vice versa.

The first ionization energy is the energy needed to remove the most loosely bound electron of an atom. The third ionization energy would be the energy required to remove the third electron from an atom.

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.
