Question

what is electropositivity and electronegativity​

Answer 1

Electro postivity refers to the ability to donate electron

Electro negativity refers to ability to receive electrons

Fluorine is the most electro negative element

Electro negativity decreases down the group

Electro negativity and electro positivity also depend on net effective charge

Answer 2

element whose electrode potentialis more positive than that of the standard hydrogen electrode which is assigned an arbitrary value of zero. Electropositive elements tend to lose electrons and form positive ions, e.g. the univalent alkali metalsLi+, Na+, K+,etc., and the divalent alkaline-earth metalsBe2+,Mg2+,Ca2+. Compare

 

Electronegativity, symbol χ, is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself. An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus.
