Why does electronegativity increase from left to right?
A. Atoms want to fill their valence shell, so they want electrons more.
B. Electrons are closer to the nucleus so they pull harder on the electrons
C. Electrons are farther from the nucleus so they pull harder on electrons
D. Atoms want to get rid of electrons in their valence shell so they easily get rid of them.
A
