Want to know something crazy?
There are new words in the World! They have actually been around for a few years but, whatever. NEW WORDS!
Here they are!
Periodic Table
Table that organizes elements based oh physical and chemical properties
WOW! WHO KNEW
Reactivity
Tendency of a substance to undergo chemical changes
Well now we know!
Periodic Trend
A regular pattern of characteristics along a row or column in the periodic table
Thanks!
Valence Electrons
The electrons on the outer most energy level of an atom
So that's what those are
Chemical Groups
Vertical column of elements on the periodic table that share chemical properties
Nice!
Chemical Periods
A horizontal row of elements on the periodic table that that have the same number of energy levels
Sweet!
Noble Gases
Elements in group 18 that are nonreactive; gases at room temperature
So that is what that is
Halogen
Elements in group 17 on the periodic table. This group tends to be mostly gasses and is very reactive
COOL!
Alkali Metal
Elements in group 1 on the periodic table. This group tends to be mostly metals and is very reactive.
I knew it!
Alkali Earth Metal
Elements in group 2 in the periodic table. This group is made entirely of metals and si reactive
Last one Yay!!! Just kidding don't say that in school
