Basic Chemistry Concepts

Front

atomic composition

Back

the types of elements that make up a substance, as well as the specific ratios of atoms of each kind of element that make it up

Front

chemical bond

Back

the connection between atoms in more complex particles

Front

chemical structure

Back

the specific way in which the bonds and atoms are arranged within the molecules of a substance

Front

crystal

Back

a solid structure whose atoms or molecules are arranged in a repeating, three-dimensional pattern

Front

extended structure

Back

a structure whose subunits occur in a constant ratio and are arranged in a repeating pattern; the subunit can be individual atoms or a molecule

Front

model

Back

a representation of an object which makes important aspects easier to see

Front

polymer

Back

a type of extended structure that is made of many smaller, repeating subunits in a chain; the repeating subunit is a unique molecule

Front

molecule

Back

a group of two or more atoms that are held together by chemical bonds; a molecule has a unique composition and structure.
