Periodic Table Basics
This person receives much of the credit for developing the periodic table.
Who is Mendeleev
The location of protons and neutrons
what is the nucleus
As you go down the periodic table, atomic number does this
what is increases
An atom that has lost or gained an electron
what is an ion
This model of the atom describes the probability of finding electrons in certain regions called orbitals
what is the quantum mechanical model
Elements in the modern periodic table are arranged based on this characteristics
what is increasing atomic number
If the number of protons and electrons are equal this is the overall charge of the atom
what is neutral
The largest atoms are located in this region
What is the lower left
A positively charged ion
what is a cation
These are the subshells/sublevels
Horizontal rows in the periodic table.
what are periods
The location of electrons
what is the electron cloud
The largest ions
what are anions
Atoms of the same element with different numbers of neutrons
what are isotopes
This is the number of orbitals in the p sublevel
what is 3
Vertical columns on the periodic table
what are groups
This person is credited with discovering the nucleus of the atom with his gold foil experiment
who is Rutherford
Based on their location in the periodic table, calcium will have ______ ionization energy than chlorine
what is lower
what are nonmetals
The second energy level/shell can hold a maximum of this many electrons
what is 8
The group number for each of the representative elements can tell you this important characteristics.
what is the number of valence electrons
This is the most electronegative element
What is fluorine
The amount of energy needed to remove the outermost electron from an atom
what is ionization energy
This is the electron configuration for carbon
what is 1s2 2s2 2p2
