what is electronegativity.?? what are the factors that effecting on electronegativity
Answers
Explanation:
c)2028 = 2 x 2 x 3 x 13 x 13
Here, 2 and 13 are in pair, but 3 needs a pair to make 2028 a perfect square.
Thus, 2028 needs to be multiplied by 3 to become a perfect square.
Hence, Answer = 3
square no.=2028x3=6084
Thanks for free points
square root of 6084=78
The tendency of an atom in a molecule to attract the shared pair of electrons towards itself is known as electronegativity.
Factors Affecting Electronegativity
1. Size of an Atom:-
A greater atomic size will result in less value of electronegativity, this happens because electrons being far away from the nucleus will experience a lesser force of attraction.
2. Nuclear Charge:-
A greater value of nuclear charge will result in a greater value of electronegativity. This happens because an increase in nuclear charge causes electron attraction with greater force.
3. Effect of Substituent:-
The electronegativity of an atom depends upon the nature of the substituent attached to that atom.
