Ernest Rutherford
The IUPAC is responsible for chemical nomeclature (naming elements)
True
False
This highlighted vertical section of the Periodic Table is
A group
A period

kinda sus, vote them out

minding its own business, why do we have to label it and give it a name? Maybe it has it's own name? Have we ever even tried just asking it what it wants its name to be?
An Electron Dot Diagram
shows how many valence electrons an atom has
shows how many neutrons an atom has
is a fun way to draw dots because drawing dots is just fun for some reason and scientists get bored sometimes
You can tell the valence electrons of Representative Elements by their Group Number. An element from Group 15 would have ____ valence electrons
5
15
4
6
This is an accurate Dot Diagram for Phosphorous, Group 15
True
False
An atom can't have more than 8 valence electrons, meaning there will never be more than 8 dots in a Dot Diagram
True
False
If you go up a group, Atomic Radii
Increases
Decreases
