Question

what is the difference between electro negative character and electro negativity of an electron?

Answer 1

Firstly, electronegativity is of an atom not an electron. Electronegativity is defined as,
the tendency of an atom of an element to attract the shared pair of electrons towards itself in a covalent bond.
Those elements showing this tendency are said to have electronegative character. There is no such difference in these terms.
