Choose the correct answer:
Among the period 2 elements the one which has high electron affinity is:
(a) Lithium
(b) Carbon
(c) Fluorine
(d) Neon

Q.

Fluorine has the highest electronegativity among the $n{s}^{2}n{p}^5$ group on the Pauling scale, but the electron affinity of fluorine is less than that of chlorine because-

Q. Among the second period elements the actual ionization enthalpies are in the increasing order Lithium Boron beryllium carbon oxygen nitrogen fluorine and neon. Then explain why beryllium has higher ionization enthalpy than Boron and oxygen has lower ionization enthalpy than nitrogen and fluorine

Q. Among fluorine and chlorine, the electron affinity of the latter is high. This is due to:

Q. Which of the given elements has the most positive electron gain enthalpy? Fluorine, Nitrogen, Neon.

Q. The atomic numbers of elements $A,B,C$ and $D$ are $Z-1,Z,Z+1$ and $Z+2$, respectively. If ${}^{\prime }{B}^{\prime }$ is a noble gas, choose the correct answers from the following statements
(1) ${}^{\prime }{A}^{\prime }$ has higher electron affinity
(2) ${}^{\prime }{C}^{\prime }$ exists in $+2$ oxidation state
(3) ${}^{\prime }{D}^{\prime }$ is an alkaline earth metal
