Match the word to the meaning by writing the letter on the line.
_____ mixture
A.
Is a substance that cannot be broken down into any simpler
substance by chemical means. Iron, oxygen and neon are
examples.
_____ element
B.
Is a substance that is made from two or more elements that
are combined together chemically. For example methane
(CH4).
_____ compound
C.
Is a combination of substances. The proportions of
pure substances can vary, so the properties vary as well.
_____ homogenous mix
D.
Is one in which different parts are visible. Salad
dressing is an example.
_____ heterogeneous mix E.
Looks the same throughout and separate components are not
visible. Solutions are examples.

The horizontal rows of the periodic table are called periods.
The horizontal columns are called families or groups.
Metals are on the left and in the center of the table.
Non-metals are located on the right-hand side of the table.
Metals are separated from non-metals by a staircase of elements called Metallica.
Atomic number is the number of protons in an atom of an element.
Atomic mass is the number of protons in an atom of an element.
An ion is an atom or group of atoms with a negative charge or a positive charge.
Noble gases are non-metals that are colourlesss, odorless gases and very
unreactive.
The maximum number of electrons in the innermost shell is two in a Bohr diagram.
The outer shell in a Bohr diagram is called the valence.
Surrounding the nucleus, and more than 10 000 times larger than it, are a series of
cloud-like energy levels called shells.
