Molécules et composés
Everything in the universe is made up of matter, and matter is composed of a combination of elements. An atom is the smallest unit of an element…
Formules chimiques
A chemical formula presents information about the proportions of atoms constituting a particular chemical compound or molecule, mainly using symbols…
Modèles moléculaires
Physical models representing molecular architectures of chemical compounds play essential roles in understanding chemistry. The use of molecular…
Classification des éléments et composés
Pure substances consist of only one type of matter. A pure substance can be an element or a compound. An element consists of only one type of atom,…
Composés ioniques : formules and nomenclature
An element composed of atoms that readily lose electrons (a metal) can react with an element composed of atoms that readily gain electrons (a…
Composés moléculaires : formules et nomenclature
Molecular compounds or covalent compounds result when atoms share electrons to form covalent bonds. Since there is no electron transfer, molecular…
Composés organiques
All living things are formed mostly of carbon compounds called organic compounds. The category of organic compounds includes both natural and…
Masse de la formule et concepts de mole des composés
Chemical formulas represent the elemental makeup of substances. For covalent compounds, the formula represents the numbers and types of atoms…
Détermination expérimentale de la formule Chimique
The elemental makeup of a compound defines its chemical identity, and chemical formulas are the most concise way of representing this elemental…
