Types of Bonds
This type of bond involves the sharing of electrons.
What is a covalent bond?
These compounds have high melting and boiling points and are brittle.
What are ionic compounds?
This theory predicts molecular shape based on electron repulsion.
What is VSEPR theory?
2 electron groups = this shape
What is linear?
These are attractions between molecules, not within them.
What are intermolecular forces?
Is CO₂ polar or nonpolar?
What is nonpolar?
This bond forms between metals and nonmetals.
What is an ionic bond?
These substances are good conductors of electricity in solid form.
What are metals (metallic bonds)?
