Hydrogen in respect to chlorine, is :
electropositive
electronegative
neutral
none of the above
B.
electronegative
Chlorine is more electronegative (electronegativity = 3.0) than hydrogen (2.1). Hence, hydrogen is electropositive in respect to chlorine.
How does the ionisation energy of 1st group elements vary ?
Increases down the group
Decreases down the group
Remains unchanged
Variation is not regular
Dominance of strong repulsive forces among the molecules of the gas (Z = compressibility factor)
depends on Z and indicated by Z = 1
depends on Z and indicated by Z > 1
depends on Z and indicated by Z < 1
is independent of Z.
