Hi, my name is Anaïs Blouin. I am 18 years old, and I have been studying at Ahuntsic College for one year. I study Natural Science which is chemistry, physics, biology, and math. It's a lot of science, I want to be a chemist and that's the reason why the topic is chemistry. I have created this glossary to help people understanding 15 words related to chemistry. Some words are difficult to pronounce, and this glossary will help with that. Each word will have a definition, an audio pronunciation, an example of how to use the word in a sentence and some may have an image.
acidic
adjective
Acidic means a substance has a pH level below 7, tastes sharp or sour, or contains acid.
Example: The acidic liquid can react with certain metals.
en: acide
atom
noun
An atom is the smallest basic unit of a chemical element that still keeps the unique properties of that element.
Example: The atom is too small to see with the naked eye.
en: atome
basic
adjective
In chemistry, "basic" refers to a substance that is a base, meaning it has a pH greater than 7, accepts protons, and reacts with acids to form salts.
Example: The cleaning product is basic and feels slippery.
en: basique
bond
noun
A bond is an attractive force that holds atoms or ions together to form molecules, crystals, and compounds.
Example: The bond between the atoms is very strong.
en: liaison
chemical
noun
A chemical is any substance that has a defined, fixed composition and is made of matter.
Example: The chemical spilled on the table during the experiment.
en: produit chimique
density
noun
Density is a measure of how heavy something is for its size, describing how tightly packed matter or particles are within a given volume.
Example: The density of water is higher than the density of oil.
en: densité
dissolve
verb
To dissolve means to mix a solid into a liquid until it becomes part of that liquid, or to officially bring an organization, relationship, or legal bond to an end.
Example: The sugar will dissolve in the water.
en: dissoudre
element
noun
An element is a pure chemical substance that cannot be broken down into simpler substances by ordinary chemical processes.
Example: Oxygen is an element found in the air.
en: élément
energy
noun
Energy is defined as the quantitative capacity or ability to do work or produce heat.
Example: The reaction produced enough energy to heat the solution.
en: énergie
evaporate
verb
To evaporate means to change from a liquid into a gas.
Example: The water will evaporate when it gets hot.
en: évaporer
ion
noun
An ion is an atom or molecule that has a net electrical charge because it has gained or lost one or more electrons.
Example: The ion was added to the solution during the experiment.
en: ion
molecule
noun
A molecule is a group of two or more atoms bonded together that forms the smallest unit of a pure substance while keeping its unique chemical properties.
Example: The water molecule is made of two hydrogen atoms and one oxygen atom.
en: molécule
neutralize
verb
To make a substance neither acidic nor basic (achieving a pH of 7), such as using an antacid to calm stomach acid.
Example: The base was added to neutralize the acid.
en: neutraliser
reaction
noun
A reaction is a behavior, feeling, action, or physical change that happens in direct response to a stimulus, event, or another force.
Example: The reaction happened when the two substances were mixed.
en: réaction
solution
noun
A solution is a uniform mixture where one substance dissolves into another.
Example: The solution turned blue after the chemical was added.
