Atomic Structure
This positively charged particle, which has a mass of 1 AMU, is found in the nucleus.
Proton
This is a measure of the amount of matter in a substance, and its SI unit is the kilogram.
Mass
In this state, atoms are tightly packed and have their own shape
Solid
The smallest particle of an element that still has the properties of that element
Atom
A mixture that has the same composition throughout
Homogeneous
This negatively charged particle has an insignificant mass and is found in the orbital outside the nucleus.
Electron
It is the amount of matter per unit of volume, calculated as mass/volume
Density
In this state, the substance expands and takes the shape of its container, and the atoms move fast
Gas
A pure substance that cannot be separated into any other substances
Element
A heterogeneous mixture with large particles that are large enough to see, settle, or be filtered out
Suspension
This is the center of the atom
Nucleus
This is the SI unit for mass
Kilogram
This is how atoms in a liquid move past one another
Sliding Past
A substance made of two or more elements.
Compound
A heterogeneous mixture of medium-sized particles that are large enough to be seen but too small to settle or be filtered out
Colloid
These layers are found outside the nucleus and contain the electrons
Orbital
Reactivity, flammability, and rust are examples of this type of property, observed only when matter changes to a different kind of matter
Chemical Property
This describes the movement of atoms in a solid
Cannot Move
The smallest part of a compound
Molecule
A homogeneous mixture with tiny particles that are too small to see, settle, or be filtered.
Solution
This force holds the protons and neutrons together within the nucleus
Nuclear Force
This is the SI unit for volume
Cubic Meter
This describes how the atoms in a solid are arranged
Tightly Packed
The use of electricity to break water into hydrogen and oxygen
Electrolysis
Solutions and colloids cannot be separated by this process, but a suspension can
Filtering
