Periodic Table Trends Warm-Up

How is the Periodic Table arranged?

• Increasing atomic mass
• Increasing atomic number
• Decreasing atomic mass
• Decreasing atomic number

Electronegativity trends are the same as:

• Atomic radius trends

• Ionization energy trends

• Both of these

• None of these

Electronegativity _________ as you go down a group.

What happens to the atomic numbers as you move from left to right on the periodic table?

• Increase

• Decrease

• Stay the same

• Nothing

Why does electronegativity decrease as you go down a group?

• As you go down a group, the outer electrons are further away from the nucleus

• As you go down a group, the nucleus is less able to attract electrons in a bond

• Both of these

• None of these

As you move down the periodic table atoms get bigger.  This is because ____________.

• The atoms have more mass.
• The atoms have more protons.
• The atoms have more energy levels
• The atoms have more nuetrons

As you move across the periodic table atoms tend to get smaller because, ______________.

• the atoms have more mass.
• the atoms have less mass
• the atoms have more protons.
• the atoms have less electrons.

What is the atomic radius?

• The distance from the nucleus to the outer boundary of an atom

• The distance from one side of an atom to the other side

• The distance around the atom

• The distance between atoms in the gas phase

• The distance between atoms in the solid phase

Electronegativity refers to an atom's ability to _____________ electrons.

• attract

• donate
