100

This positively charged particle, which has a mass of 1 AMU, is found in the nucleus.

Proton

100

This is a measure of the amount of matter in a substance, and its SI unit is the kilogram.

Mass

100

In this state, atoms are tightly packed and have their own shape

Solid

100

The smallest particle of an element that still has the properties of that element

Atom

100

A mixture that has the same composition throughout

Homogeneous

200

This negatively charged particle has an insignificant mass and is found in the orbital outside the nucleus.

Electron

200

It is the amount of matter per unit of volume, calculated as mass/volume  

Density

200

In this state, the substance expands and takes the shape of its container, and the atoms move fast

Gas

200

A pure substance that cannot be separated into any other substances

Element

200

A heterogeneous mixture with large particles that are large enough to see, settle, or be filtered out

Suspension

300

This is the center of the atom

Nucleus

300

This is the SI unit for mass

Kilogram

300

This is how atoms in a liquid move past one another

Sliding Past

300

A substance made of two or more elements.

Compound

300

A heterogeneous mixture of medium-sized particles that are large enough to be seen but too small to settle or be filtered out

Colloid

400

These layers are found outside the nucleus and contain the electrons

Orbital

400

Reactivity, flammability, and rust are examples of this type of property, observed only when matter changes to a different kind of matter

Chemical Property

400

This describes the movement of atoms in a solid

Cannot Move

400

The smallest part of a compound

Molecule

400

A homogeneous mixture with tiny particles that are too small to see, settle, or be filtered.

Solution

500

This force holds the protons and neutrons together within the nucleus

Nuclear Force

500

This is the SI unit for volume

Cubic Meter

500

This describes how the atoms in a solid are arranged

Tightly Packed

500

The use of electricity to break water into hydrogen and oxygen

Electrolysis

500

Solutions and colloids cannot be separated by this process, but a suspension can

Filtering
