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

So that what that looks like
