Explanation:
The given electronic configuration of the elements are as follows:
a) 1s2 2s22p5 - Most electronegative element
b) 1s2 2s2 2p3 - An element belonging to 3rd period and 5th group
c) 1s2 2s2 2p6 3s2 3p63d84s2 - Ad-block element
d) 1s2 2s2 2p63s23p6 - An element from 18th group
Correct answer: Option 'B' - 1s2 2s2 2p3
Explanation:
Let's analyze each option one by one:
a) 1s2 2s22p5 - Most electronegative element
The given electronic configuration represents an element with 7 valence electrons. The element with such a configuration is fluorine (F), which is the most electronegative element.
b) 1s2 2s2 2p3 - An element belonging to 3rd period and 5th group
The given electronic configuration represents an element with 5 valence electrons. This configuration corresponds to nitrogen (N), which belongs to the 2nd period and the 5th group.
c) 1s2 2s2 2p6 3s2 3p63d84s2 - Ad-block element
The given electronic configuration represents an element with 18 valence electrons. This configuration corresponds to argon (Ar), which is a member of the noble gas family and is known as a "block element."
d) 1s2 2s2 2p63s23p6 - An element from 18th group
The given electronic configuration represents an element with 8 valence electrons. This configuration corresponds to oxygen (O), which belongs to the 16th group, not the 18th group.
Therefore, the incorrect match is option 'B' - 1s2 2s2 2p3, which does not correspond to an element belonging to the 3rd period and 5th group.
