Metals generally melt at very high temperature. Amongst the following, the metal with the highest melting point will be
1 Hg
2 Ag
3 Ga
4 Cs
Explanation:
Hg, Ga, Cs are liqiud near room temperature. But Ag (sliver) is solid.

Which is chemically most active non-metal?
1
2
3
4
Explanation:
is most reactive due to highest electronegativity, low bond dissociation energy and high heat of hydration of ion.

The correct order of metallic character is
1
2
3
4
Explanation:
Metallic nature increases down the group due to increase in atomic radius, and decreases across a period, due to decrease in atomic radius. Hence, the correct order of metallic character is .

Which of the following order is correct?
1 F > N > C > Si > Ga: non-metallic character
2 F > Cl > O > N: oxidising property
3 C< Si > P > N: electron affinity value
4 All of these
Explanation:
C = –121; Si = –135; P = –60; N = 31. (1) As electronegativity increases, non-metallic character increases. (2) It is based on their SRP values, which in turns depends on bond energies, hydration energies and electron affinity values.
