scientific method
observation, hypothesis, experiment, theory, law
law
predicts what happens
theory
explain why it happens
experiments
the testing of a hypothesis under controlled conditions
matter
Anything that has mass and takes up space
chemical properties
determine how a substance can be converted into another substance
physical properties
Can be observed or measured without changing the identity of the matter
solid state
definite value, maintains shape, particles lie close together in a regular pattern
liquid state
definite volume, shape of container, close together but can move past one another
gas state
no definite volume or shape, particles are very far apart and move around randomly

cation
A positively charged ion and has fewer electrons than protons
anion
a negatively charged ion and has more electrons than protons
what state are ionic compounds
solid
how do ionic compounds behave in water
dissolve
List the diatomic elements
H, N, O, F, Cl, Br, I
what is a bond
atoms combining to form chemical compounds
hydrogen bonds are when hydrogen bonds with what elements
F, O, N
What is resonance?
two lewis structures having the same arrangement of atoms, but a different arrangement of electrons
Electronegativity
A measure of the ability of an atom in a chemical compound to attract electrons
