Ionization | MCQs

Explanation

Plasma is the fourth state of matter, following:

1. Solids
2. Liquids
3. Gases

It consists of ionized gases with equal numbers of positively and negatively charged particles.

Explanation

Cations are positively charged ions. 

Cations are formed when a metal loses its electrons.

Explanation

Acetic acid (CH3COOH) is a weak acid that only partially dissociates in water, forming a weak electrolyte solution.

It does not fully dissociate into ions like strong acids (like HCl) or strong bases (like KOH).

Explanation

According to the periodic trends, Nitrogen (N) has the largest ionization energy among the given atoms: N, P, As, and Sb. 

 Ionization energy generally increases from left to right across a period on the periodic table.

Since Nitrogen is to the left of Phosphorus, Arsenic, and Antimony, it will have the highest ionization energy.

Additionally, within a group, ionization energy decreases down the column.
