Atoms
The building blocks of Matter
Consists of Protons (+), Electrons (-),
and Neutrons (N).
Atoms of the same element always have the same number of protons – the number of protons determine the element
Question: What does the atom remind you of from class?
Life Science Connection
Question:
Is an atom smaller than a cell or a cell smaller than an atom? Explain your answer.

5. Elements
Consists of only one kind of atom,
Cannot be broken down into a simpler
type of matter by either physical or
chemical means
Can exist as either atoms or molecules.
Question:
Can I have an element that consists of atoms with different numbers of protons? Explain your answer.

6. Molecules
A molecule consists of two or more atoms of the same element, or different elements, that are chemically bound together.
In the animation above, two nitrogen atoms
(N + N = N2) make one Nitrogen molecule .
