Matter

• Anything that has mass and takes up space (volume)– Examples:

• A brick has mass and takes up space • A desk has mass and takes up space• A pencil has mass and takes up space• Air has mass and takes up space

All of the above examples are considered matter because they have mass and take up space. Can you

think of anything that would not be considered matter?

Models are often used for things that are too small or too

large to be observed or that are too difficult to be understood easily

Models

In the case of atoms, scientists use large models to explain something that is very small

Models of the atom were used to explain data or facts that were gathered experimentally.

So, these models are also theories

Atoms are so small that…• it would take a stack of about

50,000 aluminum atoms to equal the thickness of a sheet of aluminum foil from your kitchen.

• if you could enlarge a penny until it was as wide as the US, each of its atoms would be only about 3 cm in diameter – about the size of a ping-pong ball

• a human hair is about 1 million carbon atoms wide.

• a typical human cell contains roughly 1 trillion atoms.

• a speck of dust might contain 3x1012 (3 trillion) atoms.

• it would take you around 500 years to count the number of atoms in a grain of salt.

• This force plays a key role in the possible change of sub-atomic particles.– For example, a

neutron can change into a proton(+) and an electron(-)

• The force responsible for radioactive decay.– Radioactive decay

process in which the nucleus of a radioactive (unstable) atom releases nuclear radiation.
