The modern periodic table is organized according to this.
What is atomic number?
The most stable, non-reactive group of elements that have a full outer shell of electrons are known as these.
What are noble gases?
The horizontal rows of the periodic table are called this.
What are periods?
The vertical columns of the periodic table are called this.
What are groups?
Non-metals form this type of ion.
What are anions?
Who proposed the original organization of the periodic table?
Who is Dmitri Mendeleev?
Metals form this type of ion.
What are cations?
This class of elements are brittle and poor conductors of heat and electricity.
What are non-metals?
The elements in the "d" block, (the "middle" of the periodic table) are known as this.
What are the lanthanides and actinides?
Silicon (Si), Boron (B), and Tellerium (Te) are examples of this class of elements.
What are metalloids?
Elements in the same group share this.
What are valence electrons?
The size of an anion compared to its elemental counterpart.
What is bigger?
The reactive elements in group 2 are known as these.
What are alkaline earth metals?
Name which of the following elements are transition metals: Cu, Sr, Cd, Au, Al, Ge, Co.
What are: Cu, Cd, Au, and Co?
The elements in group 17 (or 7A) are known as these.
What are halogens?
The VERY reactive elements in group one are known as this.
What are alkali metals?
The shape of p orbitals.
What is dumbbell?
What gas is typically put in glass tubes used to make signs?
What orbital is Titanium in?
What is the d orbital?
The size of a cation compared to its elemental counterpart.
What is smaller?
The trend for atomic radius going down the periodic table?
What is decreasing?
This model was the first time that the nucleus was discovered by shooting alpha particles through gold foil.
What is Rutherford's model?
A Greek word meaning uncuttable.
What is atomos?
The trend for ionization energy (energy to remove one valence electron) going across a row on the periodic table.
What is increasing?
These are the properties of metals.
What are conductivity, high melting points, most are solids at room temperature, shiny, ductile, and malleable?
