What is form compounds?
The alkali metals, found in group 1 of the periodic table
are metals that do not occur freely in nature. These
metals have only one valence electron in their outer
shell. Therefore, they are ready to lose that one electron
in ionic bonding with other elements very easily. This
makes them _______ _________ especially with group
17 because they have 7 valence electrons and when the
two combine they make the magic number “8”.
$400
What are alkaline earth elements/metals?
The ____________ elements are metallic elements found
in the second group of the periodic table. They all
contain 2 valence electrons in their outermost energy
level.

These elements have 3 valence electrons and are called
the _______ family.

What is (C.) or region 3?

What is change over time as new things are
discovered?
The early work of Democritus (indivisible atoms),
Dalton (atoms are solid spheres), Thomson (Plum
pudding model), Rutherford (planetary model), and
Bohr (electrons are in shells around the nucleus) in
relation to the views on atomic theory have led us to the
current belief that electrons are found in clouds around
the nucleus (Electron Cloud Model). This shows an
example of how scientific theories can __________ when
new things are discovered.
