What are metals?
you'll find me on the left side of the periodic table.
Why are alkali metals so reactive?
Their large size and low ionization enthalpy.

Where are noble gases on the periodic table
Group 18
What are proprieties of metal?
1.) Luster
2.) Malleable(Can be made into a a long line via hammering)
4.) conduction heat
5.) conducts electricity
What do you store alkali metals in
oil
Are alkaline earth metals more or less then reactive then alkaline metals
Less
Are halogens metals or non metals
Non metals
Are noble gasses on the left or the right of the periodic table?
Right
Which metal(s) can be found in liquid form at room temp?
Mercury and Gallium
Are Alkali Metals softer or harder then most Metals.
Yes
When were alkali metals found
1808
what are anions
a negatively charged ion
Noble gases are the most reactive elements on the periodic table.
True or False?
False.
What do you call iron in its gas state?
Gaseous iron
What two alkali metals are used to make atomic clocks
Cesium and rubidium
Who discovered alkaline earth metals
Sir Humphry Davy
why do halogens form anions
halogens want to gain one electron, which gives them an extra negative charge.

True or False
False. Helium has 2 :)
