Atomic History
The term 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 number of different quantum numbers.
What is 4?
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
The 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).
The two main ways atoms can possess energy.
What is kinetic energy and absorbing photons/quanta of energy through electrons?
The frequency of a photon with an energy value of 3.8x10-19 J.
BONUS: Double or NOTHING - what are the units of frequency?
What is 5.73x1014?
Identify the atom in ground state that's 4d subshell is 2/5 full.
What is Molybdenum?
The molecular formula of a compound with an empirical formula of CH2O and a molar mass of 120.12 g/mol.
What is C4H8O4?
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).
According to this principle, electrons in an orbital must have opposite spins.
What is the Pauli Exclusion Principle?
The energy of a photon with a wavelength of 4.358x10-7 m.
