What Is The Difference Between And Element And A Compound?
An element is a material that consists of a single type of atom. Each atom type contains the same number of protons. Chemical bonds link elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds.
What is the difference between element and compound with example?
Elements are pure substances which are composed of only one type of atom. Compound are substances which are formed by two or more different types of elements that are united chemically in fixed proportions. … Some of the examples of elements are Iron Copper Gold etc. A few examples of compounds are NaOH NaCl etc.

What is an element give two examples?
an element is a substance that cannot be split into simpler substances by a chemical means . for example – hydrogen oxygen nitrogen carbon iron aluminium copper silver and gold some example of elements.
What is called element?
An element is a substance that cannot be broken down into any other substance. Every element is made up of its own type of atom. This is why the chemical elements are all very different from each other. Everything in the universe contains the atoms of at least one or more elements.
What does element mean in science?
chemical element also called element any substance that cannot be decomposed into simpler substances by ordinary chemical processes. Elements are the fundamental materials of which all matter is composed.

Is sea water mixture or compound?
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 more specifically because water is composed of hydrogen and oxygen it is a compound.
Is oxygen a compound?
*Note: pure oxygen gas consists of molecules but it is still considered an element rather than a compound as the molecules are made up of a single type of element.
Is Salt a element?
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.
Is a diamond an element?
Diamond is composed of the single element carbon and it is the arrangement of the C atoms in the lattice that give diamond its amazing properties. Compare the structure of diamond and graphite both composed of just carbon.
