What is the definition for molecules?
Molecules are the smallest units of chemical compounds that retain the chemical properties of the compound. They are made up of two or more atoms bonded together. Molecules can be simple, like oxygen (O2), or complex, like DNA.
Atoms combine chemically with each other to form what?
When atoms of two different elements chemically combine, they produce a compound. Such compounds include sodium chlorine, hydrogen fluorine, and barium sulfide. Note that if the elements are same, the result is a polyatomic element, not a compound.
What do the subscript and coefficent in a chemical equation tell us?
The subscript in a chemical equation tells us the ratio of atoms of each element present in a compound. The coefficient tells us the number of molecules or formula units involved in the reaction.
What are compounds consisting of repeated linked units?
Compounds consisting of repeated linked units are called polymers. They are large molecules formed by joining together smaller molecules called monomers through chemical bonds. Polymers can have a wide range of properties and are used in various applications, from plastics to DNA.
What is the representative unit of a covalent compound?
The representative unit of a covalent compound is a molecule. In covalent compounds, atoms share electrons to form covalent bonds, creating discrete units known as molecules. These molecules represent the smallest unit of a covalent compound that retains the properties of that compound.

What do atoms form when they stick together?
Atoms form molecules when they stick together through chemical bonds. Molecules are the smallest units of a compound that can exist independently and possess unique chemical properties based on the atoms they are composed of.
Do nonliving things have molecules?
No only living things have molecules and dna however non living things do have compounds

Are chemical molecules living?
No. Molecules are not alive. The smallest living units are cells.

What creates a compound?
a compound is any arrangement of two or more atoms of different elements; usually refers to a mass of molecules, or singular units of a compound
What are compounds consisting of repeated linked units?

What is meant by an extended or infinite-molecule solid?
These are solids formed from an infinite number of formula units (basic units) of a chemical compound.
How many molecules of NaCl are in 20grams?
The answer is 4,328.1023formula units (not molecules).
How compounds and molecules are related to elements and atoms?
Atoms are the smallest units of an element into which that element can be divided. And atoms are the building blocks of molecules. Compounds are just that - something that is compounded or has two or more elements combined to make it up. Atoms are the building blocks of compounds. An atom of one element that combines with an atom of another element creates a compound, a molecule of that compound. A compound is made up of molecules, and they can be simple two-atom molecules or can be molecules that are dozens or hundreds of atoms in size.
What is the representative unit of a covalent compound?
The representative unit of a covalent compound is a molecule. In covalent compounds, atoms share electrons to form covalent bonds, creating discrete units known as molecules. These molecules represent the smallest unit of a covalent compound that retains the properties of that compound.
