The kinds of forces that keep covalent substances together.
What is an Intermolecular forces?
100
The Theory that defines molecular shape.
What is VSEPR? (You must give these in the correct order to receive the point.)
200
The weighted average of isotopes of all the elements found in nature.
What is average atomic mass?
200
The attractiveness of electrons to a particular element in a bond.
What is electronegatvity?
200
[Ar]4s2 3d5
What is Mn or Manganese?
200
We call covalent substances "molecules" but use this name for ionic substances.
What is a formula unit?
200
The reason why water is a "bent" molecule.
What is the lone pairs of electrons are pushing the atoms as far away as possible? (See me to referee the answers if you are unsure.)
300
The number of grams in 1 lb.
What is 454.53 g? (You MUST have included the engineering unit in your answer to get these points.)
300
The ion that is produced when an element gains and electron.
What is an anion?
300
The difference between electron configurations, noble gas configurations and orbital configurations.
What is electron configurations uses letters and numbers, the noble gas configuration starts with a noble gas in parentheses and the orbital configurations uses arrows and spaces. (See me if you want me to referee the response to this question.)
300
The greatest intermolecular force.
What is hydrogen bonding?
300
The angle between hydrogen atoms on NH3.
What is 107.5 degrees. (You must have included "degrees" in your answer.)
400
The kind of property that describes a quality of an observation that does NOT depend on how much of the substance.
What is an Intensive property?
400
The three trends that are basically the same across periods and down groups.
What is electronegativity, ionization energy and electron affinity. (You don't have to note it, but the electron affinity trend STOPS at the noble gasses. )
400
The noble gas configuration for Te.
What is [Kr]5s2 4d10 5p4?
400
This property is caused by multiple hydrogen bonding sites for polar molecules and by large molecules for non-polar molecules.
What is viscosity?
400
Something that is true about H, Be, B, S, P, and elements above Period 4.
What are exceptions to the Octet Rule?
500
The experimenter who discovered that some alpha particles "bounced back" but most "went through" when they were shot at a thin sheet of metal.
Who is Rutherford?
500
The element with the greatest ionic radii between Ba+2, Sr+2, Br-1
What is Ba+2?
500
The three ideas that are used to write electron configurations.
What is Hunds Rule, Pauli Exclusion Principle and Aufbau Principle?
500
The one with the greatest boiling point between CH4, HF, and NaCl
What is NaCl? (it is ionic)
500
What will always be true about an "OH" group on a molecule?
What is it will always be "bent" or it will always form a hydrogen bond?
