Monoatomic is a term used in science to describe an atom with only one electron. This is in contrast to atoms with multiple electrons, which are called polyatomic. Monoatomic atoms are often unstable and reactive, as they readily form bonds with other atoms to complete their electron shells. Some of the most common monoatomic gases include helium, neon, argon, and krypton.
What is “Mono” in Science and How Does it Relate to Atoms?
Definition:
In science, “mono” is a prefix that means “one” or “single.” It is often used to describe objects, substances, or processes that involve only one of something.
Atoms and Monoatomic Elements:
- Atoms are the basic building blocks of matter. They consist of a positively charged nucleus surrounded by negatively charged electrons.
- Monoatomic elements are elements that exist in nature as single atoms, rather than being combined with other atoms to form molecules.
- Examples of monoatomic elements include noble gases such as helium (He) and neon (Ne), as well as metals like mercury (Hg) and sodium (Na).
Monoisotopes:
- Isotopes are variants of an element that have the same number of protons but different numbers of neutrons.
- Monoisotopes are atoms of an element that have only one naturally occurring isotope.
- For example, carbon-12 (12C) is a monoisotope, as it is the only naturally occurring isotope of carbon.
Monomers and Polymers:
- Monomers are small, simple molecules that can be linked together to form larger molecules called polymers.
- In chemistry, a polymer is a molecule composed of many repeating subunits.
- The prefix “mono” can also be used to describe polymers that consist of only one type of monomer.
Table: Summary of “Mono” Terminology in Science
| Term | Definition |
|---|---|
| Monoatomic | Consisting of single atoms |
| Monoisotope | Having only one naturally occurring isotope |
| Monomer | A simple molecule that can be linked together to form a polymer |
| Monopolymer | A polymer consisting of only one type of monomer |
Question 1:
What is mono in the context of science with atoms?
Answer:
Mono refers to the condition of an atom possessing only a single electron in its outermost shell or energy level.
Question 2:
How does the mono configuration affect the properties of an atom?
Answer:
Mono atoms exhibit low reactivity due to the stability provided by the single electron in the outermost shell, which minimizes the likelihood of forming chemical bonds.
Question 3:
What is a monoatomic gas?
Answer:
A monoatomic gas is a gas composed of mono atoms, which are atoms containing a single electron in their outermost shell and exist independently without forming molecules.
