Atomic Structure
This subatomic particle has a positive charge.
What is a proton?
This trend describes the increase in atomic size as you move down a group in the periodic table.
What is atomic radius?
The molecular geometry of a molecule with two bonding pairs and no lone pairs is called this.
What is linear?
The heat energy transferred in a chemical reaction.
What is enthalpy (ΔH)?
his is the study of the rates of chemical reactions.
What is chemical kinetics?
The region around the nucleus where electrons are likely to be found is known as this.
What is an orbital?
The trend that describes the energy required to remove an electron from an atom.
What is ionization energy?
This shape results from four bonding pairs and no lone pairs around the central atom.
What is tetrahedral?
This process requires heat to be absorbed, resulting in a positive ΔH.
What is endothermic?
A factor that can increase the reaction rate by providing more energy to the reactants.
What is increasing temperature?
This model describes electrons in defined orbits around the nucleus.?
What is the Bohr model
The term for elements that tend to lose electrons easily, located on the left side of the periodic table.
What are metals?
A molecule with three bonding pairs and one lone pair will adopt this shape.
What is trigonal pyramidal?
The law that states energy cannot be created or destroyed, only transformed.
What is the law of conservation of energy?
This term refers to the minimum energy needed for a reaction to occur.
What is activation energy?
The phenomenon that occurs when the nucleus of an atom emits a particle or energy.
What is radioactive decay?
This group of elements is known for having a full valence shell and being chemically inert.
What are noble gases?
This term refers to the three-dimensional arrangement of the atoms in a molecule.
What is molecular geometry?
The term for the amount of heat required to raise the temperature of a substance.
What is specific heat capacity?
The rate law for a reaction indicates how the rate depends on the concentration of these.
What are reactants?
The term for the average of an element's isotopes weighted by their natural abundance.
What is atomic mass?
The trend that explains why elements become more electronegative moving across a period from left to right.
What is effective nuclear charge?
The hybridization of a central atom in a trigonal bipyramidal structure.
What is sp³d?
This heat transfer occurs without physical contact between substances.
What is radiation?
This type of reaction has a rate that is directly proportional to the concentration of one reactant raised to a power.
What is a differential rate law?
