ability of an atom to attract electrons from another atom.

Electronegativity is the...

energy needed to remove the outermost electron.

ability of an atom to attract electrons from another atom.

Which element has the smaller atomic radius: potassium (K) or bromine (Br)?

potassium (K)

bromine (Br)

Which element has the greatest ionization energy: Aluminum (Al) or Chlorine (Cl)?

Aluminum (Al)

Chlorine (Cl)

Which element has the greatest electronegativity: Nitrogen (N) or Arsenic (As)?

Nitrogen (N)

Arsenic (As)

As you move down a group, atomic radius increases because -

you add more and more neutrons

you add more and more protons

you add more and more shells (energy levels)

you add more atomic mass

As you move across the periodic table from left to right, the atomic radius decreases. This is because -

the number of protons increases, so attraction to electrons increases

the number of energy levels increases

the number of electrons increases

the atomic mass increases
