Question

What you mean by electronegativity?​

Answer 1

Answer:

Electronegativity is defined as the tendency of the atom of an element in a chemical compound to attract a shared pair of electrons towards it in a covalent bond. Since electronegativity is just a tendency, it is a dimensionless quantity

Answer 2

Answer:

Electronegativity is a measure of an atom's ability to attract shared electrons to itself. On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group.
