Table that organizes elements based oh physical and chemical properties
WOW! WHO KNEW
Tendency of a substance to undergo chemical changes
Well now we know!
A regular pattern of characteristics along a row or column in the periodic table
The electrons on the outer most energy level of an atom
So that's what those are
Vertical column of elements on the periodic table that share chemical properties
A horizontal row of elements on the periodic table that that have the same number of energy levels
Elements in group 18 that are nonreactive; gases at room temperature
So that is what that is
Elements in group 17 on the periodic table. This group tends to be mostly gasses and is very reactive
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
