Periodic Trends

As you move left to right across a period, ionization energy

• increases

• decreases

• says the same

Ionization Energy is

• The ability of an atom to attract another atom's electrons

• The ability of an atom to react with water

• The energy required to remove an atom's electron

• The distance from the nucleus to the outer electrons

Which of the following atoms would have the largest radius?

• chlorine

• silicon

• sodium

• argon

Why does radius decrease as you move across a period?

• because electrons are being added

• because protons are being added

• because energy levels are being lost

• because energy levels are being added

Which of the following has the largest electronegativity value?

• neon

• fluorine

• carbon

• lithium

The ability of an atom to attract another atom's electrons to itself is called

• electronegativity

• ionization energy

• periodic trend

• coulombic attractin

Which element has the largest atomic radius?

• barium

• magnesium

• carbon

• helium

For which of these properties does lithium have a larger value than potassium?

• radius

• atomic mass

• ionization energy

• atomic number

Why does radius increase as you move down a period?

• protons are being added

• ionization energy is increasing

• protons are getting weaker

• energy levels are being added

Which element has the weakest ionization energy?

• beryllium

• oxygen

• calcium

• bromine
