These are the subatomic particles in order of charge (negative, neutral, positive)
What are electrons, neutrons, and protons?
Mole calculations
Number of moles = given mass / gram-formula mass
This rule says that there must be 8 electrons in the outermost orbital
Octet Rule
Which conclusion was proposed as a result of an
experiment during which some alpha particles
were deflected while passing through a thin sheet
of gold foil?
Atoms have small, dense, positive nuclei.
Which process occurs at the anode in an
electrolytic cell?
Oxidation
These subatomic particles are in the nucleus
What are protons and neutrons?
Percent error
((measured value - accepted value) / accepted value) x100
Na2CO3
Sodium Carbonate
According to the wave-mechanical model of the
atom, electrons are located in
Orbitals
Compared to a 0.10 M aqueous NaNO3 solution
at 1 atmosphere, a 1.0 M aqueous NaNO3 solution
at 1 atmosphere has a
lower freezing point and a higher boiling
point
This is represented by 1s^2 2s^2 2p^6 etc.
What is electron configuration?
Molarity
Moles of solute / Liters of solution
Which type of reaction occurs when an Arrhenius acid reacts with an Arrhenius base to form a salt and water?
Neutralization
The elements on the Periodic Table of the
Elements are arranged in order of increasing
Atomic number
What is the gram-formula mass of Mg(NO3)2?
148 g/mol
The mass of each proton and each neutron is
approximately equal to
1 u

MAVA = MBVB
State the molecular polarity of a CO2 molecule.
Nonpolar
The concept that matter is composed of tiny, discrete particles is generally attributed to who (a person)?
What is the molarity of a NaOH solution
containing 0.125 mole of NaOH in 0.200 L of
water?
0.625 M
As an atom in the ground state changes to an
atom in an excited state, the atom
absorbs energy
Heat
q = mC(Delta T)
What is the IUPAC name for C8H18?
Octane
Who used a cathode ray tube in an experiment that proved the existence of electrons?
