Element Families
Is lustrous, malleable, and a good conductor
What are properties of metals?
This direction increases atomic size on the Periodic Table
What is down and left?
I created the most widely recognized periodic table
Who is Dmitri Mendeleev?
My symbol is O
What is Oxygen?
I tell you the number of protons in an atom
What is the Atomic Number?
Is dull, brittle, and a poor conductor
What are properties of nonmetals?
This direction increases Ionization Energy
What is up and to the right?
Mendeleev arranged his periodic table by this
What is atomic mass?
I am the only room temperature metal
What is Mercury?
How to determine the number of neutrons in an atom
What is the atomic mass minus the atomic number?
Boron, Silicon, Arsenic
What are metalloids?
This type of element gets more reactive moving down the group
What are metals?
Mendeleev predicted this element before its discovery
What is Gallium?
I am a Noble Gas most notably used in signs
What is Neon?
The reason why atomic mass is not a round number
What is an average weight of all ions?
Is unreactive and glows with an electrical current
What are the Noble Gasses?
Electron affinity increases this direction for nonmetals
What is bottom left to top right?
Mendeleev left gaps in his periodic table for this reason
What are undiscovered elements?
The most reactive halogen
What is Fluorine?
Elements in the same period have this in common
What is the same number of orbitals?
Is soft, reactive with water, and forms 1+ ions
What are the Alkali Metals?
This is the reason that atoms get smaller across a period
What is an increase in protons & nuclear attraction?
This is how Mendeleev predicted properties of undiscovered elements
What is observing patterns in atomic mass and properties?
I was commonly used in pipes and my Latin derived name is closely resembles a common job today?
What is Lead?
This determines how reactive elements are
What are valence electrons?
