What is formed when two or more elements combine?
When two or more elements combine, they form a compound. Compounds are composed of atoms of different elements bonded together in specific ratios.
What are compounds composed of?
Compounds are composed of two or more different elements that are chemically bonded together. These elements combine in fixed ratios to form specific compounds with unique chemical and physical properties.
When two or more elements combine chemically it is called?
When two or more elements combine chemically, it is called a chemical compound. In a chemical compound, the elements are bonded together in specific ratios to form a new substance with unique properties.
How do you combine elements to make other elements?
nuclear fusion
What elements can lead combine with?
Elements can combine with other elements to form compounds through chemical reactions. The elements that can combine with each other depend on their reactivity and chemical properties. Some common examples of elements that can combine include hydrogen, oxygen, carbon, nitrogen, and metals like iron and copper.
Who said elements combine in specific proportion?
john Dalton
Do elements always combine in specific ratios?
The Law of Definite Proportions says that a given chemical compound always contains the same proportion by mass of its constituent elements. This is NOT the same as saying that elements always combine in a specific ratio, because they can combine in different ratios in different compounds. An example of this might be copper oxide which can be CuO or Cu2O, showing a different ratio of copper to oxygen. So, the answer to the question, as asked, is no, elements do not always combine in specific ratios.
What is a fixed proportion in chemistry?
A fixed proportion in chemistry refers to the specific ratio in which elements combine to form compounds. This means that the elements in a compound are always present in the same proportion by mass. For example, water is always composed of hydrogen and oxygen in a 2:1 ratio by mass.
What is made up of of two or more elements in specific proportion?
A Molecule
Who said that Elements combine in specific proportions?
John Dalton
What is formed when two or more elements combine?
When two or more elements combine, they form a compound. Compounds are composed of atoms of different elements bonded together in specific ratios.
What are compounds a result of?
Compounds are a result of chemical reactions that occur when two or more elements combine in a specific ratio to form a new substance with unique properties different from the original elements. The atoms in a compound are held together by chemical bonds, such as ionic or covalent bonds, which give the compound its characteristic structure and properties.
What year did schrodinger say elements combine in specific proportions?
The 20th century
When elements combine to make a compound is it always in the same proportion?
No, the elements are not always in the same proportion. For example, two atoms of hydrogen combine with one atom of oxygen to make a single molecule of water. But one atom of hydrogen combines with one atom of fluorine to make a single molecule of hydrogen fluoride. The numbers of atoms involved depends on the number of electrons available in the outer electron clouds of the atoms involved.
What scientist said that elements combine in specific proportions?
The scientist who proposed the law of definite proportions was Joseph Proust. He stated that elements always combine in specific and fixed proportions by mass to form compounds.
What is a substance made of two or more elements chemically combined in a specific proportion is called a?
This is a chemical compound.
Who wanted to know why elements combine in specific proportions?
John Dalton in 1803
