are elements made of molecules?

A molecule is the smallest particle of a substance that exists independently. Molecules of most elements are made up of only one of atom of that element. Oxygen, along with nitrogen, hydrogen, and chlorine are made up of two atoms. ... A compound is a substance formed when two or more elements are chemically joined.

Compounds contain two or more different elements. Water is a molecule because it contains molecular bonds. ... It is not a compound because it is made from atoms of only one element - oxygen. This type of molecule is called a diatomic molecule, a molecule made from two atoms of the same type.

Elements: are pure substances made up of only l type of atom. ... Compounds: are pure substances that are made up of more than l type of atom and can be broken down or decomposed into its individual elements by chemical methods, but cannot be separated by physical methods.

A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds. Hydrogen gas (H2) is a molecule, but not a compound because it is made of only one element.

When people speak about particles it is about stuff smaller than any molecule. Generally, about electrons, protons, neutrons, quarks, neutrinos, positrons, etc; the parts of an atom. Molecules are two or more of the same or different atoms. ... Molecules are made from atoms and combinations of particles creates the atom.

When two or more atoms of different elements join together, we call it a compound. All compounds are molecules, but not all molecules are compounds. That is because a molecule can be made up of two atoms of the same kind, as when two oxygen atoms bind together to make an oxygen molecule.

Atoms are the basic building blocks of ordinary matter. Atoms can join together to form molecules, which in turn form most of the objects around you. Atoms are composed of particles called protons, electrons and neutrons.

An atom is the smallest particle of matter and is made of protons, neutrons, and electrons. Molecules are made of two or more atoms combined together. An element is a substance made of only one type of atom, and three examples of elements are carbon, oxygen, and gold.

atoms and elements?) ... A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing just one proton and one electron.

Atoms consist of a nucleus made of protons and neutrons orbited by electrons. Atoms are the basic units of matter and the defining structure of elements.

So, in summary: element - a basic substance that can't be simplified (hydrogen, oxygen, gold, etc...) molecule - two or more atoms that are chemically joined together (H2, O2, H2O, C6H12O6, etc...)

Compounds Are Different Elements Molecules are groups of two or more atoms, but there is a special sub-group of molecules, too. These are compounds, and a compound is a group of two or more different atoms chemically bonded together. The key here is that compounds are made of at least two different elements.

All matter is made up of substances called elements, which have specific chemical and physical properties and cannot be broken down into other substances through ordinary chemical reactions. Gold, for instance, is an element, and so is carbon. There are 118 elements, but only 92 occur naturally.

An atom is a particle of matter that characterizes a chemical element. It is the smallest part of ordinary matter. ... A compound is a substance that is made up of two or more different elements that are chemically joined, such as H2O,CO,NaCl . Note: All compounds are molecules, but not all molecules are compounds.

A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds. ... There are two main types of chemical bonds that hold atoms together: covalent and ionic/electrovalent bonds. Atoms that share electrons in a chemical bond have covalent bonds.
