Problem 1
Due date: Tue Oct 15 11:59:59 pm 2013 (CDT)
1. Which of the following statements about quantum numbers are true? (Use the drop down menus to choose "True" or
"False" for each statement. You must get all of the statements
correct at the same time.)
•

•
Choices: True, False.
The labels on atomic orbitals (1s, 2p, etc.) are based on
quantum numbers.
Quantum numbers describe the number of protons and
neutrons in an atom.
n, l, ml, and ms are quantum numbers.
The ms quantum number has just 2 allowed values.
One quantum number can fully describe any atomic
orbital.

Choices: True, False.
Non-metals generally have more negative electron affinities than metals.
Elements in the same row of the periodic table tend to
have similar chemical properties.
The more negative an element’s electron affinity is, the
more likely that element is to form an anion.
Electronegativity is a measure of the relative tendency
of an atom to attract the electrons of a chemical bond
in which it participates.
Electronegativity is the tendency of an atom to lessen
its electron density when bonded to another atom.
Elements in the same column of the periodic table tend
to have similar chemical properties.
