Ionic vs Covalent Bonding

What elements generally make an ionic bond?

• metal and nonmetal
• 2 or more nonmetals
• metal
• none of the above

What elements generally make a covalent bond?

• metal and nonmetal
• 2 or more nonmetals
• metal
• none of the above

In chemical compounds, covalent bonds form when

• the electronegativity difference between two atoms is very large.
• electrons are completely transferred between two metals.
• pairs of electrons are shared between two nonmetal atoms.
• two nonmetal atoms are attracted to each other by opposite charges.

An ionic bond forms when 

• Valence electrons are shared
• a sea of mobile electrons surround the cations
• valence electrons are transferred between atoms
• none of the above

Predict the bond that will form between Be and F.

• Ionic
• Covalent

What type of bond would form between O and O?

• Polar Covalent

• Non-Polar Covalent

• Ionic

What type of bond would form between Li and O?

• Polar Covalent

• Non-Polar Covalent

• Ionic

The bond between C and Cl is polar covalent. That means

• there is a pair of electrons shared equally between them

• there is a pair of electrons shared unequally between them

• an electron will be stolen from one and given to the other

What type of bond would form between O and H?

• Polar Covalent

• Non-Polar Covalent

• Ionic

What is the measure of an atoms ability to pull electrons towards itself when it is bonded to another atom?

• Electron Affinity

• Ionization Energy

• Electronegativity

• Atomic Radius
