What elements does a compound contain?
A compound is a substance that contains two or more elements chemically combined in a fixed proportion. The elements carbon and hydrogen combine to form many different compounds. One of the simplest is called methane, in which there are always four times as many hydrogen particles as carbon particles.
What is a compound and what does it consist of?
compound. [ kŏm′pound′ ] A substance consisting of atoms or ions of two or more different elements in definite proportions joined by chemical bonds into a molecule. The elements cannot be separated by physical means. Water, for example, is a compound having two hydrogen atoms and one oxygen atom per molecule.
How many elements does a compound contain?
two
A compound is a unique substance that consists of two or more elements combined in fixed proportions. This means that the composition of a compound is always the same.

Is a compound made up of sodium and chlorine?
Chemically, table salt consists of two elements, sodium (Na) and chloride (Cl). Neither element occurs separately and free in nature, but are found bound together as the compound sodium chloride.
What is compound short answer?
1) In chemistry, a compound is a substance that results from a combination of two or more different chemical element s, in such a way that the atom s of the different elements are held together by chemical bonds that are difficult to break.
What is compound in simple words?
A compound is a substance formed when two or more chemical elements are chemically bonded together. Example 1: Pure water is a compound made from two elements – hydrogen and oxygen. The ratio of hydrogen to oxygen in water is always 2:1. Each molecule of water contains two hydrogen atoms bonded to a single oxygen atom.
