Chemical Bonding
This type of bond involves the sharing of electrons between two nonmetal atoms
What is a covalent bond
This is the simplest ratio of elements in an ionic compound.
What is a formula unit?
This is a solid that is produced as a result of a chemical reaction in a solution.
What is a precipitate?
This is the substance that is being dissolved in a solution.
What is the solute?
This term describes a solution that contains the maximum amount of solute it can hold at a given temperature.
What is a saturated solution?
This bond forms when atoms with very different electronegativities transfer electrons, creating attracted ions
What is an ionic bond?
These are molecules made of three or more atoms.
What are polyatomic molecules?
This type of reaction involves the combination of two or more substances to form a single new compound.
What is a synthesis reaction?
This effect describes the scattering of light by particles in a colloid or suspension
What is the Tyndall effect?
This process occurs when a solid changes directly into a gas.
What is sublimation?
This bonding theory describes metal atoms as positive ions arranged in a "sea" of negative electrons.
What is the metallic bond?
This is the strongest type of intermolecular force, occurring between polar molecules containing hydrogen.
What are hydrogen bonds?
This type of reaction releases more energy (usually as heat) than it takes in to break bonds.
What is an exothermic reaction?
According to the Arrhenius definition, these substances produce hydrogen ions (H+) in water.
What are acids?
It is the process where a gas changes directly into a solid.
What is deposition?
This measure describes an atom's ability to attract electrons to itself while already bonded.
What is electronegativity?
This property of metals allows them to be hammered or rolled into thin sheets.
What is malleability?
This notation in a chemical equation indicates that a substance is dissolved in water.
What is aqueous (aq)?
This scale, ranging from 0 to 14, measures the acidity or alkalinity of a solution
What is the pH scale?
This term refers to any pure substance made of only one kind of atom.
What is an element?
These are covalent bonds where electrons are shared unequally, creating partial electrical charges.
What are polar covalent bonds?
These compounds are generally good insulators and have relatively low melting points.
What are covalent compounds?
This principle states that the total number of atoms for each element must be the same on both sides of a chemical equation.
What is a balanced equation?
This ion (H3O+) is formed when a bare proton joins a water molecule.
What is the hydronium ion?
Thomson originally called electrons by this name.
What are corpuscles?
