Nuclear Chemistry
This is the name for what happens when one nucleus turns into another.
What is radioactivity? (Also accept radioactive decay or nuclear decay)
This is the formula for the oxygen molecule.
What is O2?
All elements under hydrogen (the alkali metals) have this number of valence electrons.
What is one?
This is the strongest type of intermolecular force; only molecules with a hydrogen atom attached to an oxygen, fluorine, or nitrogen can have it.
What are hydrogen bonding forces? (Do not accept "hydrogen bonds" or hydrogen forces)
What is the balanced chemical equation?
This type of radiation involves two protons and two neutrons.
What is alpha radiation?
This is the name of the ionic compound NaCl
What is sodium chloride?
Oxygen, sulfur, and selenium all have this many valence electrons.
What is six?
This is the weakest type of intermolecular force; every molecule has it.
What is disperson forces? (Also accept LDF's, London dispersion forces, Van der Waals forces, etc.
This is the amount of time needed for half of a radioactive sample to decay.
What is the half-life?
This type of radiation is lighter and more dangerous than alpha radiation.
What is beta radiation? (also accept gamma radiation)
This covalent compound has two nitrogens and two hydrogens, which its name tells you!
What is dinitrogen dihydride?
The HCl molecule has this many total valence electrons
What is eight?
This type of force can only be experienced by polar molecules.
What is dipole-dipole force?
This number helps you convert from moles to particles (meaning atoms, molecules, or ions).
What is Avogadro's number? (also accept 6.02x1023)
In this type of nuclear reaction, two small nuclei join together; it only happens in the sun!
What is nuclear fusion?
The ionic compound formed from the magnesium and nitrate ions has this formula.
What is Mg(NO3)2?
Ozone, O3, has this many valence electrons.
What is eighteen?
This type of force is the strongest in methane, CH4
What are dispersion forces?
To find this quantity, convert both reactants to find which one produces the least product.
What is the limiting reactant? (also accept theoretical yield)
In this type of nuclear reaction, one large nucleus falls apart to make several smaller particles.
What is nuclear fission?
This is the name of the compound Cu3(PO4)2.
What is copper (II) phosphate?
This is the number of valence electrons in the ammonium ion, NH4+.
What is eight?
These are all of the possible forces in the HCl molecule.
What are dispersion and dipole-dipole forces?
This is the molar mass of carbon dioxide, CO2.
What is 44 g/mol? (must include units)
