The atom
This small particle of a atom carries a negative charge
Electron
The joining together of two or more atoms to form a new particle
Molecules
One kind of atom
Element
Why was the periodic table of elements created
To make it easier to identify elements in their characteristics
Anything that takes up space and has mass can be a solid liquid or gas
Matter
Made up of the protons and neutrons, that's part of the atom contains nearly all the mass of the atom
Nucleus
Molecules made up of atoms from different elements
Compound
Two or more atoms same or different
Molecule
What information is included on the periodic table of elements
atomic number
Chemical symbol
Elament name
Atomic mass
The number of protons in an atom
Atomic number
There's small particle of a atom carries a neutral charge
Neutron
A shorthand method that lists the types of atoms in a molecule includes element simple in a number to indicate the number of atoms of each element
Chemical formula
Two or more different elements
Compound
This is the most commonly used word for the element
Element name
The mass of an atom equals number of protons plus the number of neutrons
Atomic mass
This is the area where electrons travel around the nucleus
Shell
This small particle of a atom carries a positive charge
Proton
All________are molecules, but not all________ are compounds.
1 compounds
2 molecules
Designated by the number of protons in the nucleus, this determines horizontal placement on the table
Atomic number
The center of the atom made up of the protons and neutrons
Nucleus
This is the basic building block of all matter
Atom
Chemical formulas include
Numbers and chemical symbols
Purpose of chemical formulas
A shorthand way to show types in numbers of atoms in a molecule
This is determined by the weight of the atom
Atomic mass
One of the three main parts of an atom has a negative charge, moves quickly around the nucleus
Electron
