What are the two most commonly found elements in the universe
Hydrogen and Helium
The postulates of particle theory
What is
All matter is made up of tiny particles
All particles of one substance are the same. Different substances are made up of different particles
Particles are always moving
Particles move faster at high temperatures compared to lower temperatures
Particles are attracted to one another, these forces are stronger when particles are closer together

Judgment of host
The word that the word "atom" is derived from
What is atomos, the Greek word for indivisible?
The definition of chemical property and chemical change
What is
Chemical property - how a substance changes to form one or two new substances
Chemical change - a transformation in the chemical makeup of a substance, irreversable

Five differences between metal and nonmetal
(With exceptions) What are
Metals are only solids - nonmetals found in all states
Metals are heavy - nonmetals are light
Metals are hard, nonbrittle - nonmetals are hard, brittle
Metals are good conductors of heat and electricity - nonmetals are bad conductors of heat and electricity
Metals are ductile and fragile - nonmetals are neither
Metals have high melting and boiling points - nonmetals have low melting and boiling points
Metals produce ringing sounds on collision - nonmetals do not
Metals are lustrous and can be polished - nonmetals are not and cannot be
