all human beings collectively; the human race; humankind. the quality or condition of being human; human nature. the quality of being humane; kindness; benevolence.

Answer 2

They can be distinguished as follows: s-block elements:

(i) They have got the general electronic configuration of the valence shell ns1−2 .

(ii) They are all metals.

(iii) Their compounds are mostly ionic.

(iv) They are generally strong reducing agents.

(v) They mostly impart characteristic colour to the flame.

(vi) They have low ionisation energies.

(vii) They show fixed oxidation states.

p-block elements:

(i) The general valence shell electronic configuration of p block elements in ns2p1−6 .

(ii) They are mostly non-metals.

(iii) Their compounds are mostly covalent.

(iv) They are generally strong oxidizing agents. (v) Mostly they do not impart colour to the flame. (vi) They have got comparatively higher value of i.e (vii) They show variable oxidation states.
