What is electronegativity?
Electronegativity is the ability of the atom to attract electrons when the atom is in a compound
100
What are valence electrons?
Valence electrons are outermost electrons or electrons in the highest energy sublevel

Explain general electronegativity trends
In general, electronegativity values decrease from top to bottom within a group. For representative elements, the values tend to increase from left to right across a period.

500
Why does ionization energy increase from left to right across a period?
Because nuclear charge increases but the shielding effect stays the same
500
What is he difference between electronegativity and ionization energy?
Ionization energy is the energy needed to remove an electron and electronegativity is the tendency to attract electrons when the atom is in a compound
