How big is an Atom?
Matter is made up of a matter is made up of atoms.
Matter is any substance that has mass and occupies space
(everything around you)
Atomic theory is a theory of the nature of matter ( The theory states that either is made of small parties called atoms)
What Are Elements
The smallest piece of an element is called an atom.
An element is a substance that cannot be ( building blocks of matter ) broken apart into other substances.
MOST SUBSTANCES ARE MADE UP FROM TWO OR MORE ELEMENTS!
An atom is the smallest particle of any elements that still has the properties of that element.
100 MILLION ATOMS = MEASURE OF 1CM.
ATOMS ARE INDIVISIBLE!
Electrons are negatively charged particles in an atom.
Electrons move rapidly, have negative charge, and an extremely small mass.
Electron clouds or orbitals show the probability of finding an electron in a particle location.
A nucleus is a small center core of an atom made up of protons and neutrons.
A proton is a particle with a positive electrical charge.
Neutrons are particles with no charge.
Atoms have an equal number of protons and electrons.
The arrangement of atoms changes its substance.
Some examples are coal ( 90-98 pure carbon) Graphite (arranged in sheets) Diamonds (packed tightly together) Buckyball (soccer ball)
