These are also called families, the columns of elements in the periodic table
What are groups?
This group contains the most commonly used metals, 1 or 2 valence electrons.
What are transition metals?
These are generally gases or soft crumbly solids
What are nonmetals?
He organized the known elements into a periodic table and left specific locations open for elements that he predicted would be discovered (and were!)
Who is Demitir Mendeleev?
Lewis Dot Diagram
Draw the Lewis Dot Diagram for Chlorine. See answer key
These are special electrons in the outermost energy level
What are valence electrons?
They are chemically uniform,, "salt-producing," very reactive. Non metals.
Halogens
These are semiconductors, lustrous, but brittle.
What are metalloids?
His work resulted in the revision of the periodic law and the atomic number being used as the organizing factor for the elements of the periodic table?
Who is Henry Moseley?
Orbital Notation
Write out the Orbital Notation for Phosphorus (see answer Key)
This is an atom or group of atoms with a positive or negative charge
What is an ion?
This group does not have period or group numbers
What are Inner Transition Metals?
These are solid, lustrous, and malleable
What are metals?
His "Law of Octaves" was orignially mocked, but was actually correct and instrumental in developing what we now know as the periodic table.
Who is John Newlands?
Electron Configuration
Write out the electron configuration for Potassium. See answer key.
This is an atom's lowest energy state.
What is ground state?
This group is very chemically reactive, we do not find them in nature in their pure metallic form.
What are the Alkali metals?
These are generally good conductors or heat & electricity.
What are metals?
This principle says it is impossible to know both the energy or momentum and the exact position of an electron at the same time.
What is the Heisenberg uncertainty principle?
Noble Gas Configuration
Write out the Noble Gas Configuration for Strontium
This is when something acts as both a particle & a wave.
What is wave-particle duality?
This group is mostly geologic minerals that dissolve slightly in water, love to form 2+ cations.
What are Alkaline Earth Metals?
These are poor conductors of thermal energy and electricity.
What are nonmetals?
Orbital Notation utilizes both the ______________ ____________ principle and __________ rule.
What are the Pauli Exclusion Principle and Hund's rule?
Lewis Dot Diagram
Draw the Lewis Dot Diagram for Sulfur. See answer key.
