Chemical Compounds

Unit 1, Section 2

• We're going to look at the shapes of some molecules

• Can we find some patterns for elements and where they are in a molecule?

Guided Reflection

• Molecule - formed when two or more atoms are connected by chemical bonds

• Compound - type of molecule that contains at least two different elements

Compounds and Molecules

• Chemical Bond - a force that holds two atoms together in a molecule

• Chemical bonds form when electrons move between atoms

Chemical Bonds

Electrons can form chemical bonds by either:

• Transferring from one atom to another

• Being shared between two atoms

How Do Electrons Move?
