Basic Chemistry Info.

1. Unit #1 – Part 2

2.  branch of science dealing with the
structure, composition, properties,
and reactive characteristics of
substances, especially at the atomic
and molecular levels
 RXNs are constantly happening in the
human body

3.  Matter – “stuff’ of the universe,
occupies space and has mass, has
three states
 Energy- massless and doesn’t take up
space, ability to do work, can change
from 1 state to another
6 types of energy mentioned in the
textbook (page 28)

4.  Elements – one or more elements
make up matter, cannot be broken
down any further by ordinary
means,
◦Need to know
O,C,P,K,N,S,H,Ca,Na,Cl,Mg,I,Fe
◦96% of body weight C,O,H,N

5.  Atoms – make up elements and make them unique,
contain protons, neutrons and electrons
 Atomic symbol – are abb. for the
name
 Atomic number - # of protons, can’t
change
 Atomic mass – protons added to
neutrons

6.  As a class, come up with a method to
show all of the elements and
information provided on page 30 of
your textbook.
 Be sure to also show the proportion of
each element compared to the next.
 Be creative and work together.
 Everyone must participate.
 This will be displayed.

7.  Molecule – 2 or more atoms
combine chemically
 Compound – 2 or more different
atoms bind together to form a
molecule
 Molecules & Compounds

8.  Bonds – energy relationship
keeping electrons of atoms
together, 3 main types (hydrogen,
covalent, ionic)

9.  Lack C and tend to be small,
simple molecules
 Ex: water, salts and some acids
and bases

10.  Contain C
 Ex: carbs, lipids, proteins and NA

11.  For your assigned macromolecule, read the
assigned text and perhaps complete some
research.
 Prepare a PowerPoint that covers the information.
This presentation should include diagrams,
charts, etc… 12 slide requirement (min.)includes
title slide and citations slide
 Prepare a ‘cheat sheet’ of the 5 main
facts/definitions. (Copies will be made and
distributed to the other students after the
presentations)
 Present your information to the class.
