polar and nonpolar covalent compounds

How do covalent bonds form?

• Donating & receiving valence e- between atoms.
• Opposite slight charges attract each other between compounds.
• Scientists are still not sure how they form.
• Sharing valence e- between atoms.

What type of bond is shown in this image?

• Nonpolar Covalent
• Van der Waals force

What elements generally make an ionic bond?

• metal and nonmetal
• 2 or more nonmetals
