Electronegativity trend

What is electronegativity?

• The tendency of an atom to lose an electron.

• The tendency of an atom to gain an electron.

• The ability of an atom to form bonds.

• The measure of an atom's size.

How does electronegativity generally change across the periodic table?

• It increases as you go down a group and from right to left across a period.

• It decreases as you go up a group and from left to right across a period.

• It increases as you go up a group and from left to right across a period.

• It decreases as you go down a group and from right to left across a period.

When comparing the electronegativity of two elements, which factor is generally considered more significant?

• The strength of the nucleus.

• The number of protons.

• The number of energy levels.

• The atomic mass.

Which element has a higher electronegativity: Aluminum (Al) or Gallium (Ga)?

• Gallium, because it has more energy levels.

• Aluminum, because it has fewer energy levels.

• Gallium, because it has more protons.

• Aluminum, because it has a stronger nucleus.

Which element has a higher electronegativity: Rubidium (Rb) or Iodine (I)?

• Rubidium, because it has fewer protons.

• Iodine, because it has more energy levels.

• Rubidium, because it has a weaker nucleus.

• Iodine, because it has more protons.
