What is a monatomic element?
Some elements are monatomic, meaning they are made of a single (mon-) atom (-atomic) in their molecular form. Helium (He, see Fig. 2.8) is an example of a monatomic element. Other elements contain two or more atoms in their molecular form (Fig.
What are single atoms?
A single particle of any element listed in the periodic table is an atom. The number of protons present determines an atom’s order in the periodic table, along with its name, symbol, and chemical identity.
What are the 7 metric prefixes?
- In the SI, designations of multiples and subdivision of any unit may be arrived at by combining with the name of the unit the prefixes deka, hecto, and kilo meaning, respectively, 10, 100, and 1000, and deci, centi, and milli, meaning, respectively, one-tenth, one-hundredth, and one-thousandth.

What does the prefix mono mean?
mono- a combining form meaning “alone,” “single,” “one” (monogamy); specialized in some scientific terms to denote a monomolecular thickness (monolayer) and adapted in chemistry to apply to compounds containing one atom of a particular element (monohydrate).
Does mono mean 5?
A prefix that means “one, only, single,” as in monochromatic, having only one color. It is often found in chemical names where it means “containing just one” of the specified atom or group, as in carbon monoxide, which is carbon attached to a single oxygen atom.
Does Poly mean 2?
By definition, mono- specifies the quantity (one); but poly- does not specify the quantity—it simply says “more than one” or “much/many”. Poly- could be two; it could be a million.
Does Poly mean many?
Scientific definitions for poly A prefix meaning “many,” as in polygon, a figure having many sides. In chemistry, it is used to form the names of polymers by being attached to the name of the base unit of which the polymer is made, as in polysaccharide, a polymer made of repeating simple sugars (monosaccharides).
Is Deca a 10?
Deca- is a combining form used like a prefix meaning “ten.” It is used occasionally in technical and scientific terms. Deca- comes from Greek déka, meaning “ten.” A related Latin-origin form is deci-, from Latin decimus, “tenth.” Want to learn more?
Can kissing cause sore throat?
Ah, the so-called “kissing disease”! It definitely deserves its nickname, because mono is caused by a virus that is easily transmitted through kissing, according to Mayo Clinic. One of its trademark signs is intense fatigue, although others include a sore throat and swollen lymph nodes.

Is hydrogen h1 or H2?
Hydrogen, H, is the lightest element with the atomic number 1. It is a colorless, odorless, tasteless, and highly flammable gas with the molecular formula H2.
What is 2 H2O called?
It is also called dihydrogen monoxide. The 2 is the subscript for H symbolises the presence of 2 Hydrogen atoms. Thus, we can say that there is hydrogen bonding in water.
What is H2 called?
H2 is also called molecular hydrogen.It consists of two protons and two electrons. Consequently it is the most common form of Hydrogen because it is stable with a neutral charge. H2 is not a free radical. It is the antioxidant in ‘hydrogen-rich’ water.
How are mono di twins made?
Identical twins come from the same egg and sperm. The egg and sperm join together as in any conception, but the egg splits in two shortly after fertilization. Because they come from one egg, they’re sometimes referred to as monozygotic twins.
How do you name a molecular compound?
- A molecular compound is usually composed of two or more nonmetal elements.
- Molecular compounds are named with the first element first and then the second element by using the stem of the element name plus the suffix -ide. Numerical prefixes are used to specify the number of atoms in a molecule.
