Light and Energy
What defines the distance between crests?
What is Wavelength
what are electron configurations
the summary of where the electrons are around a nucleus.
Electron configuration = Address of an electron
What is the name of this element - H
Hydrogen
Define a Family
a group of elements with similar chemical properties
What is waters chemical formula?
H20
frequency and wavelength are ________ proportional
Inversely
Electrons will only occupy a p-orbital after _______________________
the previous s-orbital is completely full
What is the name of this element - Au
gold
What is a period
a horizontal row on the periodic table
what are the 3 most common states of matter
solid, liquid, gas
How is the symbol for frequency "v" pronounced?
"new"
When single electrons occupy different orbitals of the same sub level they all have ________ spins
different/opposite
What is the name of this element - Br
Bromine
What is the outermost shells called
Valence shell
what part of your body has the most iron
your blood
What is the speed of light?
2.998 × 108 m/s
who's rule is this...?
● Electrons always enter an empty orbital before pairing up.
● All of the electrons in singly occupied orbitals have the same spin (to maximize total spin).
Hund's rule
What is the name of this element - At
Astatine
What is the relationship between the valence shell number and and the row numbers on the left-hand side of the periodic table?
Row number corresponds to the “n” (or, principal energy level) of highest occupied energy level (Valence shell)
What do you call an atom that has more protons than electrons?
a cation
What is Planck’s constant? (include units!!!)
6.626 × 10–34 J·s
What is the Pauli Exclusion Principle
Only 2 electrons per orbital (and they must have opposite spin)
What is the name of this element - Sg
Seaborgium
What is the relationship between where an element is located within a“block” of the table in Model 1 and the superscripted (raised, like anexponent) value appearing at the end of the electron configuration for that element?
The column number = the superscript/number of electrons
who invented the periodic table
Dmitri Mendeleev
