Does a chemical compound consists of two or more elements?
chemical compound, any substance composed of identical molecules consisting of atoms of two or more chemical elements. All the matter in the universe is composed of the atoms of more than 100 different chemical elements, which are found both in pure form and combined in chemical compounds.
Can a pure compound have more than one element?
A molecule may be homonuclear, that is, it consists of atoms of one chemical element, as with two atoms in the oxygen molecule (O2); or it may be heteronuclear, a chemical compound composed of more than one element, as with water (two hydrogen atoms and one oxygen atom; H2O).
What is a chemical compound composed of only two elements?
A binary compound is a compound formed from two different elements. There may or may not be more than one of each element. A diatomic compound (or diatomic molecule) contains two atoms, which may or may not be the same. Cl2 Not binary (only one type of atom), but diatomic (two atoms).
Is compound pure?
Compounds are made of only one kind of molecule. The molecule is made up of two or more kinds of atoms. There is no physical change that can separate the compounds into more than one kind of substance. This makes a compound a pure substance.
What is two or more atoms of the same element or different elements chemically combined called?
A molecule consists of two or more atoms of the same element, or different elements, that are chemically bound together.
Is every compound a pure substance?
Yes, compounds are pure substances as they are made of molecules that are formed by the union of atoms of different elements through chemical bonding. Hence, molecules are the fundamental unit of compounds. Each compound is made of only one type of molecule.
What is pure compound in chemistry?
A pure chemical compound is a chemical substance that is composed of a particular set of molecules or ions that are chemically bonded. Other chemical substances commonly encountered in pure form are diamond (carbon), gold, table salt (sodium chloride), and refined sugar (sucrose).
Do compounds only have 2 elements?
A compound is a unique substance that forms when two or more elements combine chemically. A compound always consists of the same elements in the same ratio. If the same elements combine in different ratios, they form different compounds.
Is a compound a pure substance?
Yet both compounds and elements are considered pure substances. Pure compounds are created when elements combine permanently, forming one substance. In general, a mixture can be separated into its original components, while a pure compound cannot.
