In the process some of the mass of the hydrogen is converted into energy. It is the reaction in which two atoms of hydrogen combine together, or fuse, to form an atom of helium. What will happen if you combine 2 hydrogen atoms?įusion is the process that powers the sun and the stars. Because there is both a strong enough attraction betweeen atoms and room for electrons in the outer energy level of both atoms, the atoms share electrons. When two hydrogen atoms come close enough to each other, their electrons are attracted to the proton of the other atom. What happens when two hydrogen atoms combine? In chemistry, the law of multiple proportions states that if two elements form more than one compound, then the ratios of the masses of the second element which combine with a fixed mass of the first element will always be ratios of small whole numbers. The atomic number of an element is equal to the number of protons that element contains. Each contains a different number of protons and neutrons, giving it its own atomic number and mass number. … Which property is unique for each element?Įach element has its own unique properties. Compounds can be broken down using chemical reactions. Compounds are also pure substances that are composed of elements in definite proportions. What is the difference between elements and compounds?Įlements are substances that are pure in their nature and are composed of a single atom. When two hydrogen atoms combine with one oxygen atom, it becomes the compound water. All compounds are molecules, but not all molecules are compounds. If atoms combine that are of two or more different elements, we call that a compound. In other words, when two or more elements or compounds react so as to form one single compound, then the chemical reaction that takes place is called a combination reaction.Ī molecule is formed when two or more atoms join together chemically. The combination of two or more elements to form one compound is called a combination reaction. What is it called when two or more compounds combine? When two or more elements combine in a fixed proportion, the resulting substance is called a “compound”. What is formed when two or more atoms bond together in fixed proportions?Ī chemical compound is a substance that is composed of two pr more different elements that are chemically bonded with each other in a fixed proportion by mass. Thus when two or more elements bond together in specific proportions, a compound is formed. Example: Atom is the smallest unit of matter which is composed of electrons, protons and neutrons. Metal is an element which lose electrons to attain stability. When two or more elements bond together in specific proportions is formed an ion a metal compound atom? Most elements on Earth bond with other elements to form chemical compounds, such as sodium (Na) and Chloride (Cl), which combine to form table salt (NaCl). When two distinct elements are chemically combined-i.e., chemical bonds form between their atoms-the result is called a chemical compound.
