Atomic History
The name for the first quantum model of the atom that proposes energy levels for electrons.
What is the planetary model?
The state of an electron with its lowest possible energy.
What is ground state?
This happens to frequency as wavelength increases.
What is decreases?
The maximum number of orbitals in the p sublevel.
What is 3?
You do this to find the percent composition of a compound.
What is put the grams of the element over the grams of the compound times 100%?
This scientist ushered in the theory of quantum mechanics when studying the hydrogen atom.
Who is Niels Bohr?
The value of c.
What is the speed of light, 3 x 108 m/s?
Wavelength must be in these units before plugging the values into Planck's equations.
What is meters?
The maximum number of orbitals in the f sublevel.
What is 7?
The percent composition of H in HCl
What is 2.77%?
This scientist proposed that electrons live in "clouds" as opposed to orbitals.
Who is Schrodinger?
The electromagnetic spectrum in increasing wavelength for the following waves: radio waves, gamma rays, visible light.
What is gamma rays, visible light, radio waves?
State the full electron configuration for the element Titanium (Ti).
What is 1s22s22p63s23p64s23d2?
The percent composition of Cl in MgCl2
A drawing of the first quantum mechanical model of the atom.
Drawing of an atom with nucleus in the center, and electrons in orbits around it (planetary model).
According to this principle, electrons in an orbital must have opposite spins.
What is the Pauli Exclusion Principle?
The frequency of a photon with an energy value of 3.8x10-19 J.
What is 5.73x1014?
Identify the atom in ground state that's 4d subshell is 2/5 full.
What is Molybdenum?
Double or NOTHING: List 2 different units of frequency
Hertz, cycles per second, 1/s, s-1
The drawing of the second quantum mechanical model of the atom (that we learned in class).
Drawing of an atom with a dense central nucleus and many dots representing "clouds" where electrons can be found around the nucleus (Schrodinger's model).
The two main ways atoms can possess energy.
What is kinetic energy and absorbing photons/quanta of energy through electrons?
The energy of a photon with a wavelength of 4.358x10-7 m.
What is 4.558x10-19 J?
The orbital diagram and number of unpaired electrons in cobalt (Co).
What is 3 unpaired electrons? (See board for correct orbital diagram)
The empirical formula of N12O30.
What is N2O5?
