-Compounds
-Mixtures
Mixture: A combination of two or more substances that do not combine chemically but remain the same individual substances.
Compound: A substance made up of two or more different types of atoms bonded together
Similarities: both are formed/made
of two or more substances
Differences:
A compound is more of
a chemical substance
And mixtures are substances in
which you can remove certain parts
(Example: trail mix)
Comparing:
-Compounds
-Elements
Element: A substance that cannot be broken down into a simpler substance by ordinary chemical changes. Elements consist of only ONE type of atom.
Compound: A substance made up of two or more different types of atoms bonded together.
Examples:
Compound: Dry ice
- Dry ice is really just frozen carbon dioxide, and carbon dioxide
is a compound
Element: Gold
- All the atoms gold contains are the same which makes
gold an element
Comparing:
- Atoms
- Molecules
Atom: the smallest particle of
an element that has the chemical
properties of that element.
Molecule: a group of atoms held
together by covalent bonds so
that they move as a single unit
Examples:
Molecules: Water
- Theses droplets of water are made of water molecules; two hydrogen atom and 1 oxygen atom
Atom: carbon
- Carbon is one of the 3 main atoms.
Proton - found in nucleus, positively charge + + + + + + BALANCED
Neutron - found in nucleus, neutral (no charge)
Electron - electron cloud, negatively charges - - - - - - BALANCED
Bonds:
Ionic: metals with nonmetals - give and take
Covalent: non metals with nonmetals - sharing
Physical Properties: maintains chemical make up
Chemical Properties: chemical identity
Covalent bond:
C: 4
O: 6
