Answer: The question is incomplete and the options are not given but here are d options from another website.
a. Electronegativity increases as you move to the right of the periodic table.
B. Electronegativity is the ability of an atom to attract electrons.
c. A very electronegative atom easily gives up electrons.
d. Electronegativity increases with a decreased number of protons.
The correct options are
a. Electronegativity increases as you move to the right of the periodic table.
B. Electronegativity is the ability of an atom to attract electrons.
d. Electronegativity increases with a decreased number of protons.
Explanation:
This is because Electronegativity is the ability of an element to attract pair of electrons to itself.
Electronegativity increases as a result of increase in protons and when there is more electron pull.
As, the size of an element decreases, the valence electrons are attracted near to the nucleus. Therefore, there is increase in attraction between shared electron and nucleus.
