Who said that a given compound always contains the same elements in the same proportions by mass?
This statement was made by French chemist Joseph Proust and is known as the Law of Definite Proportions. It states that a compound always contains the same elements in the same proportions by mass regardless of the source of the compound.
Are all elements made up of different elements combined?
No, each element is in basic form and are always only made up from themselves. When elements are combined this is a compound.

Who developed the law of definite composition?
The law of definite composition was developed by French chemist Joseph Proust in the late 18th century. He formulated this law based on his experiments with chemical compounds, which stated that a given compound always contains the same elements in fixed proportions by mass.
Do compounds always contain the same elements in the ratio?
No, compounds do not always contain the same elements in the same ratio. Compounds are formed by the combination of two or more elements in fixed proportions by mass. The ratio of elements in a compound is determined by the chemical formula of the compound.
Is metal a compound?
No, a compound is something made out of two or more elements.
Is magnesium compound or element?
