Scientists
Scientist who came up with the idea of quantum jumps and stated that electrons are found in energy levels around the nucleus.
Who is Niels Bohr?
The electron configuration for sodium (no shortcut) written with proper formatting.
What is 1s²2s²2p⁶3s¹?
The orbital diagram shown below is right/wrong (if wrong, correct it). To save space it is written horizontally instead of vertically.
What is wrong? The arrows in the 2p need to be placed in individual orbitals (boxes) before doubling up.
The large number (the first quantum number) in the electron configuration tells you this information.
What is the energy level?
The electron filling rule that states electrons will fill the lowest energy level first before filling the next energy level
What is the Aufbau Principle?
Scientist who came up with the Uncertainty Principle, which states that you can know an electron's speed or position but not both at the same time.
Who is Werner Heisenberg?
The Noble gas shortcut configuration for titanium.
What is [Ar]4s²3d²?
The orbital diagram shown below is right/wrong (if wrong, correct it). To save space it is written horizontally instead of vertically.
What is right?
What is the shape of the orbital?
s = sphere
p = dumbbell
d = complex
f = very complex
The electron filling rule that states that electrons will fill orbitals individually before doubling up (bus rule)
What is Hund's Rule?
Scientist who came up with the Wave Equation.
Who is Erwin Schroedinger?
The name of the element that corresponds to the electron configuration of 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁶6s²4f¹⁴5d8
What is Platinum (Pt)?
The electron configuration shown below is right/wrong (if wrong, correct it). The electron configuration is for zinc (Zn).
1s22s22p63s23p63d104s2
What is wrong? 4s comes before 3d.
1s22s22p63s23p64s23d10
The little numbers (the 3rd quantum number) tells you this information.
What is the number of electrons in each sublevel?
The electron filling rule that states that two electrons must have opposite spins when in the same orbital.
What is the Pauli Exclusion Principle?
Scientist who discovered the electron using a cathode ray tube and came up with the first modern model of the atom (the Plum Pudding Model).
Who is J.J. Thompson?
The number of valence electrons in the following electron configuration: 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d⁶
What is 2 valence electrons?
The electron configuration shown below is right/wrong (if wrong, correct it). The electron configuration is for gallium (Ga).
1s22s22p63s23p64s23d104p1
What is right?
Definition of valence electrons
What are the electrons that are used for bonding which are located in the highest energy level (outermost ring) of the atom?
The number and location of valence electrons for the element shown in the orbital diagram below.
What is 2 valence electrons located in the 7s sublevel?
The scientist who discovered the nucleus using the Gold Foil Experiment.
Who is Ernest Rutherford?
The number of valence electrons in the following electron configuration: 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p³
What is 5 valence electrons?
The Noble gas shortcut for electron configuration shown below is right/wrong (if wrong, correct it). The electron configuration is for tin (Sn).
[Xe]5s24d105p2
What is wrong? The Noble gas configuration has the Noble gas from the previous row in brackets.
[Kr]5s24d105p2
The number of boxes/lines for each sublevel/orbital is determined from this information. Example: the reason why the p sublevel has 3 boxes/lines and the d sublevel has 5 boxes/lines.
What is the number of orientations for each shape?
The name of the element that has the orbital diagram shown below.
OK
What is Thorium (Th)?
