substances
the noble gases
They are called compounds.
Compounds are one or more elements combined to make a compound. Like H2o is oxygen and hydrogen combined.
Copper, Silver, and Gold occur as elements instead of compounds.
If the properties of elements change when they are mixed together, the mixture is called a compound. Compounds result from chemical reactions between elements, where the atoms are bonded together in specific ratios. These compounds often possess unique properties distinct from their individual element components.
The elements and compounds to the right of the equations are called products.
Mixture.
Noble gases
ReactivityThe ease and speed with which an element combines with other elements and compounds is called the "reactivity" of the element.
Atoms of different elements can " stick together " ( making compounds ) via elements sharing or trading arrangements called
oxides
Chemical compounds are formed from chemical elements.
ReactivityThe ease and speed with which an element combines with other elements and compounds is called the "reactivity" of the element.
ReactivityThe ease and speed with which an element combines with other elements and compounds is called the "reactivity" of the element.
ReactivityThe ease and speed with which an element combines with other elements and compounds is called the "reactivity" of the element.
This would be called an element, or a mono-atomic compound.
