This term refers to the vertical columns on the periodic table
What are groups?
Group 1 elements are known by this name.
What are alkali metals?
This principle states electrons fill the lowest energy orbitals first.
What is the Aufbau Principle?
This trend refers to the distance from the nucleus to the valence shell electrons.
What is atomic radius?
An atom that has lost or gained electrons is called this.
What is an ion?
This term refers to the horizontal rows on the periodic table.
What are periods?
Group 2 elements are called this.
What are alkaline earth metals?
This principle says only two electrons can occupy an orbital.
What is the Pauli Exclusion Principle
Atomic radius does this as you move left to right across a period.
What is decrease?
This energy is needed to remove an electron from an atom
What is ionization energy?
Protons determine this property of an element
What is its identity?
Group 17 elements are highly reactive and are called this.
What are halogens?
This rule states atoms are most stable with 8 electrons in their outer shel
What is the octet rule?
Atomic radius does this as you move down a group.
What is increase?
This energy is released when an atom gains an electron.
What is electron affinity?
Electrons determine this property of an element.
What are chemical properties?
These elements are non-reactive and found in the far right column.
What are noble gases?
: Name the blocks used in electron configuration.
What are s, p, d, and f blocks?
This trend measures how strongly an atom attracts electrons in a bond
What is electronegativity?
Metals tend to form ions with this type of charge.
What is positive
The valence electrons are responsible for this.
What is chemical reactivity?
These elements have properties of both metals and non-metals.
What are metalloids?
This term describes the arrangement of electrons in an atom.
What is electron configuration?
Electronegativity increases in this direction across the periodic table.
What is left to right and bottom to top?
Non-metals tend to form ions with this type of charge.
What is negative
