Electronegativity Practice

Electronegtivity is

• Ability to pull the electrons

• Ability to pull the protons

• Ability to pull the neutrons

Electronegativity (a)   as you go down a group.

Do noble gases have electronegativity values?

• yes

• no

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 a bigger effective nuclear charge

• the atoms have less electrons.
