What is an atom?
Negatively charged particle in atom, located outside the nucleus.
What is an ELECTRON?
Electrons on the outermost shell, which bond with other atoms.
What are VALENCE ELECTRONS?
Most reactive group of metals on the periodic table, due to their single valence electron.

Attraction where two atoms share electrons.
What is a COVALENT BOND?
Sum of proton and neutron weight.
What is ATOMIC WEIGHT?
What is the OCTET RULE?
Located on the right side of the periodic table, creating negative ions.
What is a NON-METAL?
Attraction that holds ions together.
What is an IONIC BOND?
Solid where all atoms are connected by ionic bonds.
What is a CRYSTAL LATTICE?
Form of matter that cannot be broken down by chemical or physical changes.
What is an ELEMENT?
Positively charged center of an atom, holding most of the atom's mass.

What are PROTONS?
Found on the left side of the periodic table, creating positive ions.
What is a METAL?
Two or more elements bonded.
What is a COMPOUND?
Solid where all atoms are connected by covalent bonds.
What is a NETWORK SOLID?

What is an ISOTOPE?
These particles are in the nucleus, but have no charge.
What are NEUTRONS?
Row in the periodic table.
What is a PERIOD?
The most inert group of elements, due to their satisfied electron numbers.
What is Group 18, the NOBLE GASES?
Group of atoms bonded.
