There is a science quiz over chapter 2 vocabulary.
The words they need to know are
mass number - the number of protons plus the number of neutrons in an atom
Homogenous mixture- A mixture that is mixed evenly throughout and cannot see the separate substances
Heterogenous misture - A mixture that is mixed unevenly and you can see the separate substances
Proton - Positive charged particle
neutron - a particle with no charge
Mixture - two or more substances that are joined together by physical means
Isotope - Atoms of the same element that have different number of neutrons
Ion - Atom with a positive or negative charge
element - any atoms that have the same number of protons and chemical properties
Electron - particle with negative charge
compound - two or more substances that are chemically bonded together
atomic number - the number of protons in an atom
The test is matching.
Thanks
