Elements & Atoms  from k12Reader

Everything around you is made of matter. Matter is
made of at least one element. An element is made of
atoms that are all the same kind. It is a pure form of
matter. Elements join together with other elements to
make the different materials that we see and use
every day.

Some common elements that you might have heard
about are oxygen, carbon, helium, gold and silver. If you
have a lump of silver, all of the atoms that make up that
lump of silver are the same. We know there are 118 different elements.

The list of elements is arranged on a scientific chart.
The chart is called the Periodic Table. Each element is
grouped with other similar elements. Elements can be
metals, nonmetals, or semi-metals. Semi-metals have
some of the characteristics of metals, and some of the
characteristics of nonmetals. Metals, nonmetals, and
semi-metals each have their own section on the table.
Each group is coded with different colors.

Each element has its own box on the chart. The box
shows the element’s name, symbol and atomic number.
The atomic number tells us how many (positively charged)
protons are in each atom of the element. It also shows
their properties. Properties are how an element looks and
acts in different situations.
