Periodic Table Groups
This is the group of elements that exists in the second vertical column.
What is Alkaline Earth Metals?
Aside from neutrons, the other known nucleon is this subatomic particle
What is a proton?
This refers to the strength in which protons of one atom attract the electrons of another.
Experiment that discovered all atoms have a nucleus that houses its positive charge.
What is the Gold Foil Experiment?
Refers to the number of nucleons present in an atoms nucleus.
What is mass number?
This is the nonreactive group that exists in the far right column.
What is the noble gases?
This is the negatively charged wave-particle duality that exists outside an atom's nucleus.
What is an electron?
This refers to distance from an atom's nucleus to its outer most shell.
What is atomic radius?
An experiment that showed all atoms contain tiny, negatively charged electrons.
What is the Cathode Ray Experiment?
Refers to average weight of all isotopes of an element measured in atomic mass units.
What is relative atomic mass?
This group contains important elements that are essential for human life.
What is the nonmetals.
This is the area of an atom in which electrons exist.
What is the electron cloud?
This is the minimal energy required to remove the most loosely bound valence electron from an atom.
What is ionization energy?
This experiment measured and identified electron charge.
Refers to the number of protons in an atom's nucleus.
What is atomic number?
These metals often have valence electrons in two shells instead of one.
What is the transition metals?
The subshells in which electrons spent 90% of their time within their electron energy shells.
What are electron orbitals?
This refers to an elements level of reactivity and tendency to loose electrons.
What is metallic character?
What is electrical conductivity?
What is the lanthanides?
This is the type of subatomic particle that helps stabilize protons and can sometimes lead to spontaneous decay.
What is neutrons?
The change of energy of a neutral atom when an electron is added to form an anion.
What is electron affinity?
What is malleability?
