Atomic Structure and Periodic Table
This subatomic particle determines the identity of an element.
Proton
Bohr proposed that electrons orbit the nucleus in these fixed paths.
Energy levels
This type of nuclear reaction powers the sun.
Fusion
This gas law states that pressure and volume are inversely related.
Boyle’s Law
One mole contains this many representative particles.
6.022×10^{23} (Avogadro’s number)
The number of protons in an atom of oxygen.
8
This quantum number determines the shape of an orbital.
Angular momentum quantum number (ℓ)
Alpha decay emits this type of particle.
Helium nucleus (2 protons, 2 neutrons)
The ideal gas law is expressed with this equation.
PV = nRT
The molar mass of CO₂ is approximately this many grams per mole.
44.01 g/mol
This periodic trend increases from left to right across a period.
Electronegativity
The Pauli Exclusion Principle states this about electrons in the same orbital.
No two electrons can have the same set of quantum numbers
In beta decay, a neutron transforms into this particle and an electron.
Proton
According to KMT, gas particles are in constant motion and collide in this manner.
Elastically
This type of bond involves the transfer of electrons.
Ionic bond
Elements in Group 18 are known by this name.
Noble Gasses
The energy of a photon is directly proportional to this property of light.
Frequency
This must be conserved when balancing nuclear equations.
Mass number and atomic number
As temperature increases, the average kinetic energy of gas molecules does this.
Increases
The empirical formula of a compound is the simplest ratio of these.
Atoms of each element
This is the effective nuclear charge experienced by valence electrons in a neutral fluorine atom.
+7
This model replaced Bohr’s and describes electrons as existing in probability clouds.
Quantum mechanical model
This process splits a heavy nucleus into two lighter nuclei, releasing energy.
Fission
Real gases deviate from ideal behavior under these two conditions.
High pressure and low temperature
To find the number of moles from mass, you divide mass by this.
