Why bismuth does not from pentahalides?

Correct Answer - A Owing to the non-availability of d-orbital in its valence shell, N cannot expand its octet and, therefore, it cannot form `NF_5`.

An element has electronegativity on Mulliken Scale is 2.8 than what is the electronegativity of element on All - Red Roschow Scale

Correct Answer - B `X_(m) = 2.8 X_(P) " " X_(P) = (2.8)/(2.8) = 1` `X_(P) = 0.744 + X_(AR)` `1 = 0.744 + X_(AR)` `X_(AR) = 1 - 0.744 =...

Fluorine has the highest electronegativity among the `ns^(2) np^(5)` group on the Pauling scale, but the electron affinity opf fluorine is less than t

Correct Answer - D There is more interelectronic repulsion in `2p`-subshell of fluorine than chlorine `(3p)`. So extra electron will be added easily in `3p`-subshell fo chlorine as compared to `2p`-subshell...
