Why are we studying chemistry?
“What are you made of? Just as buildings are made from bricks, steel, glass, and wood, living things are made from chemical compounds. When you eat food or inhale oxygen, your body uses these materials in chemical reactions that keep you alive. If the first task of an architect is to understand building materials, then the first task of a biologist is to understand the chemistry of life.”

The Basic Unit of Matter
• Atom- smallest unit, or part, of any “thing.”
• Atom comes from Greek word atomos- “unable to be cut”
• 100 million atoms

PAUSE.
• What is the smallest unit of matter called?

Subatomic Particles• Sub-marine• Sub-zero• Sub-atom-ic
There are 3 particles found within an atom:• Protons• Neutrons• Electrons
Particles- “Small things”

![Page 9: DO NOW](https://reader035.fdocuments.in/reader035/viewer/2022070422/568165f6550346895dd91c2c/html5/thumbnails/9.jpg)
Subatomic Particles Carry a Charge
• Protons- positive charge (+)
• Neutrons- neutral, or no charge
• Electrons- negative charge (-)
![Page 10: DO NOW](https://reader035.fdocuments.in/reader035/viewer/2022070422/568165f6550346895dd91c2c/html5/thumbnails/10.jpg)
• Protons (+) and Neutrons have the same weight.
• Protons (+) are Neutrons make up the Nucleus, which is at the center of an atom.
• Electrons (-) are found outside the nucleus.
