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.
Also Is water an element?
Answer. Water is a compound. It contains more than one element: hydrogen and oxygen atoms are joined together; as illustrated in the video clip Elements and Compounds, above.
Subsequently, Is salt a element compound or mixture? Salt is another compound. Its chemical formula is NaCl, which stands for sodium chloride.
Are salt and water element or compound? No, salt water is not a compound, rather it is a homogeneous mixture of Sodium Chloride ions and water. To be more precise, we can call it to be a solution. When salt is added to water and mixed, no new compound is formed.

Why is water an element?
An element is a substance composed of a single type of atom. Hydrogen (element symbol H) and oxygen (element symbol O) are examples of elements. … So, water is made from elements, but is not itself an element. Before people knew about atoms and molecules, water was considered to be an element.
Is water an element or compound or mixture?
Water is a compound because it is made up of water molecules. There is no such thing as water atoms. Water molecules are made of hydrogen and oxygen atoms, in the definite proportion of two hydrogens for one oxygen.
Is pure water an element or compound?
Water, H2O, is a pure substance, a compound made of hydrogen and oxygen.
Is table salt a compound or element or mixture?
An example of a compound is table-salt. It is a compound because it is made up of two different types of atom – in this case sodium and chlorine. The chemical name for table-salt is NaCl.
Is salt an element or compound or homogeneous or heterogeneous?
Hence, common salt is a compound. Compounds are made up of elements, combined in a fixed ratio and has different properties than constituent atoms. Common salt exhibits both the characteristics.
Is salt an element compound or mixture homogeneous or heterogeneous?
Saltwater acts as if it were a single substance even though it contains two substances—salt and water. Saltwater is a homogeneous mixture, or a solution. Soil is composed of small pieces of a variety of materials, so it is a heterogeneous mixture. Water is a substance.
What kind of mixture is salt and water?
A solution is a mixture that is the same or uniform throughout. Think of the example of salt water. This is also called a “homogenous mixture.” A mixture that is not a solution is not uniform throughout.
What is salt and water mixture?
A solution is another name for a homogeneous mixture. … Salt dissolved in water is a solution. The major component of a solution, called the solvent, is typically the same phase as the solution itself. Each minor component of a solution (and there may be more than one) is called the solute.
Why salt water is a mixture?
Salt water does not have a uniform composition and we can divide salt and water by simple physical process of evaporation (by boiling the salt water). Thus, salt water is a mixture, with salt as the solute and water as the solvent.
Is sodium a salt or metal?
Sodium is a chemical element with the symbol Na (from Latin natrium) and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is

What makes a compound a salt?
salt, in chemistry, substance produced by the reaction of an acid with a base. A salt consists of the positive ion (cation) of a base and the negative ion (anion) of an acid. … The term salt is also used to refer specifically to common table salt, or sodium chloride.
What is sodium 23 used for?
sodium nitroprusside an antihypertensive agent used in the treatment of acute congestive heart failure and of hypertensive crisis and to produce controlled hypotension during surgery; also used as a reagent.
Why water is a compound and not an element?
Water is formed by the chemical reaction between a hydrogen molecule and an oxygen molecule. … This implies that water is a compound and not an element. This is because an element’s properties remain uniform irrespective of external conditions. -Water is stable at room conditions.
Is water an element or a compound give two reason in support of your answer?
Answer: Answer: Water is a compound because of the following reasons: It is composed of two different elements, hydrogen and oxygen which cannot be separated by physical methods. They can be separated only by electrolysis.
Is H2O an element if not explain your answer?
Water consists of hydrogen and oxygen. … Its formula is H2O and it can be broken down into its components, so it is not an element. The hydrogen and oxygen atoms of water do not contain the same number of protons as each other — they are different substances.
Is h20 A compound mixture or element?
For example, water (H2O) is a compound consisting of two hydrogen atoms bonded to an oxygen atom. The atoms within a compound can be held together by a variety of interactions, ranging from covalent bonds to electrostatic forces in ionic bonds.
Is water a common compound?
Water is a very common substance, not just on Earth, but also in space. Although water usually occurs in space as a solid and occasionally as a gas and relatively rarely as a liquid, the most common compound is Hâ‚‚.
Is water a homogeneous mixture?
Many of the liquids you encounter every day are examples of homogeneous mixtures. … Water – another example of homogeneous mixture; all but the purest water contains dissolved minerals and gases; These are dissolved throughout the water, so the mixture presents in the same phase and is homogeneous.
