An atom is the smallest particles of matter.
A protons have a postitive charge and a neutron have a nuetral charge.
the atomic number
Atomic Mass helps to determine how many neutrons are in an atom.
Since there are the same number of protons and electrons in an atom, the charges cancel each other out.
An element is a prue substance that can't be broken down into simpler substances by ordinary chemical means.
Each kind of atom is element
An electron and it has a negative charge
Protons, neutrons, electrons
the atomic structure
A substance produced when elements combine and whose properties are different from each of the elements.
Compound is formed chemically, while a mixture is when a pure substances combine but do not join.
Both are combinations of pure substances, but homogeneous mixtures can easily be seperated by physical means. Homogeneous mixtures can not.
Compounds and mixtures are both combinations of pure substances. Mixtures are joined but compounds do not.
A compound is formed chemically, while an element is formed physically.
Matter is the only thing that has a mass or volume.
Mass is the amount of matter in a substance
Volume is the amount of space the substance occupies
A combination of compounds and elements that has not formed a new substance and whose proportions can be changed without changing the mixtures identity?
A neutral particle formed when atoms share electrons.
