Electronegativity and Polarity Review

Electronegativity is...

• how good an atom is at attracting electrons
• the ability of an atom to lose electrons
• the energy required to remove an electron from a specific atom
• how easy it is to make friends. 

Which element has the greater ionization energy?

• Magnesium (Mg)

• Phosphorus (P)

The polarity of a bond is determined by...

• The sum of the electronegativities of the two atoms

• The difference in the electronegativities of the two atoms

• The charges of the atoms

• None of the Above

Partial charges are present in which type of bond?

• Ionic

• Nonpolar Covalent

• Polar Covalent

• Both Polar Covalent and Ionic

Order the types of bonds based on the charge of their molecules. (lowest amount of charge to greatest)

• Polar Covalent --> Ionic --> Nonpolar Covalent

• Ionic --> Nonpolar Covalent --> Polar Covalent

• Ionic --> Polar Covalent --> Nonpolar Covalent

• Nonpolar Covalent --> Polar Covalent --> Ionic
