Final answer:

The answer provides suitable words for the given blanks in a chemistry context, explaining various separation processes in chemistry.


Explanation:

(a) Atomicity of hydrogen is monatomic.

(b) In loading process, impurities settle down rapidly, get deposited to the suspended particles, and make them heavy.

(c) The combining capacity of an element is known as its valency.

(d) Insects can be separated from wheat by winnowing.

(e) Salt is obtained from sea-water by the process of evaporation.

(f) When milk, cooled after boiling, is poured onto a piece of cloth, cream is left behind on it. This process of separating cream from milk is an example of filtration.

(g) Impurities settled at the bottom when muddy water was kept overnight in a bucket. The clear water was then poured off from the top. The process of separation used in this example is called sedimentation followed by decantation.
