What is a simple definition of a molecule?
Listen to pronunciation. (MAH-leh-kyool) The smallest particle of a substance that has all of the physical and chemical properties of that substance. Molecules are made up of one or more atoms.
What are 3 examples of molecules?
Examples of Molecules:
- Carbon dioxide – CO2
- Water – H2O.
- Oxygen we breathe into our lungs – O2
- Sugar – C12H22O11
- Glucose – C6H12O6
- Nitrous oxide – “Laughing gas” – N2O.
- Acetic acid – part of vinegar – CH3COOH.
What is a molecule for kids?
A molecule is two or more atoms joined (or “bonded”) tightly together. The number and kinds of atoms in a molecule, and the way they are arranged, determine what substance it makes. For example, a molecule made of two oxygen atoms joined to one carbon atom forms carbon dioxide, a colorless gas.
What are 10 examples of molecules?
Here are examples of common molecules:
- H2O (water)
- N2 (nitrogen)
- O3 (ozone)
- CaO (calcium oxide)
- C6H12O6 (glucose, a type of sugar)
- NaCl (table salt)
What is molecule and element?
A molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. Molecules are made up of atoms that are held together by chemical bonds. Examples of such elements are oxygen and chlorine. The atoms of some elements do not easily bond with other atoms.
What are molecules with example?
Molecules of compounds have atoms of two or more different elements. For example, water (H2O) has three atoms, two hydrogen (H) atoms and one oxygen (O) atom. Methane (CH4), a common greenhouse gas, has five atoms, one of carbon (C) and four of hydrogen (H, see Fig. 2.9).
What is a molecule example?
A molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. Examples of such elements are oxygen and chlorine. The atoms of some elements do not easily bond with other atoms. Examples are neon and argon.
What is a molecule for middle school?
Molecule – the smallest particle of a substance that retains all the properties of the substance and is composed of one or more atoms. Compound – made up or consisting of two or more existing parts or elements. A compound must have 2 different elements! A molecule is simply 2 bonded atoms.
Is a molecule an atom?
A molecule is an electrically neutral group of two or more atoms held together by chemical bonds. Atoms and complexes connected by non-covalent interactions, such as hydrogen bonds or ionic bonds, are typically not considered single molecules.
What is molecule in biology?
noun, plural: molecules. A tiny or a very small piece (of something). (biology or biochemistry) An extremely small particle or substance, especially at cellular or structural level, as a biomolecule.
What is molecule and its types?
A molecule is defined as two or more atoms of the same element different element that are bound together. A molecule may be homonuclear, which means, it consists of atoms of one chemical element, as with oxygen (O2); or it may be heteronuclear, a chemical compound composed of more than one element, as with water (H2O).
