Intro to Chem Bonds

Eden has discovered a new composed of cesium and oxygen. What type of bond is likely holding these atoms together?

• We need more info to predict this.
• Ionic
• Polar Covalent
• Non Polar Covalent

Assuming that zinc and gallium formed a bond what type would you predict? 

• Non Polar Covalent
• Polar Covalent
• Ionic

What makes a covalent bond different from an ionic bond?

• Covalent bonds are the result of valence electrons being shared.
• Ionic bonds deal with core electrons being lost or gained.
• Covalent electrons are the result of the entire atom becoming charged.
• Ionic bonds form when core electrons are shared.

What is happening to make a polar covalent bond?

• More than one core electron has been transfered
• Unequal sharing of a pair of valence electrons.
• Both atoms have the same electronegativity.
• Both a core electron and a valence electron are transfered.

How many valence electrons does Aluminum have? 

• 3
• 13
• 14
• 27

How many valence electrons does the atom in the diagram have? 

• 2
• 3
• 5
• 10

Why are ions formed?

• Because atoms like to change
• Because atoms want 8 valence electrons
• Because atoms have the same number of protons and electrons
• Because atoms gained neutrons

The bond between Ca and Br is an example of which type of chemical bonding?

• Ionic Bond

• Covalent Bond

• Both bonds

• Neither bond

In water, H and O bond is an example of which type of chemical bonding?

• Ionic Bond

• Covalent Bond

• Both bonds

• Neither bond

Ionic compounds

• Share electrons
• Transfer electrons
• Contain a sea of electrons
• Steal electrons
