What is electropositivity and electronegativity? Between group 1 and group 17, which is electropositive and electronegative?

Electopositivity is the measure of the ability of elements to donate electrons to form positive ions. Whereas the Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. Group 1 is more electropositive than group 17 and group 17 is more electronegative than group 1.
