Electron Configuration
What is the electron configuration of Hydrgen?
1S1
HCl+H2O→H3O++Cl-
A, B, CA, CB
What is molarity?
The number of moles of solute per liter of solution.
What are valence electrons and why do we show them in Lewis structures?
Outer Electrons that form bonds
What is ionization energy?
Energy required to remove an electron from an atom.
What is the electron configuration of Phosphorus?
1S22S22P63S23P3
NaOH+H2O→Na++OH-
B, A, CA, CB
What are units of molarity?
what does the octet rule say about how atoms like to have their electons?
Atoms want 8 outer electrons
What is electronegativity?
Atom's ability to attract an electron to itself.
What element has electron configuration 1S22S22P63S23P64S23d8?
Nickel
NH3+N2O⇌NH4++OH-
B, A, CA, CB
How do you calculate molarity?
Divide the number of moles of solute by the volume of the solution in liters.
What is a lone-pair and what effect does it have on a mclecure?
Non-bounding electrons that charge shape
How does atomic radius change as you move down a group?
It increases
What element has electron configuration [Xe]4f145d106s26p6?
Radon
CH3COOH+H2O⇌CH3COO-+H3O+
A, B, CB, CA
If you have 2 moles of solute in 4 L of solution,what is the molarity?
0.5 M (2/4)
Draw the Lewis structure for oxygen
O=O
How does electronegativity change as you move down a group?
It decreases
What is the electron configuration of Fermium?
HS-+H2O⇌H2S+OH-
A, B, CA, CB
What volume of solution is needed to contain 0.5 moles of solute in a 0.25 M solution?
2 L (0.5/0.25)
O=C=O
Why does ionization energy increase across a period?
Nuclear charge increases and atomic radius decreases which leads to stronger attraction between the nucleus and valence electrons.
