what is the difference between a molecule of an element and a molecule of a compound?
310740
The only difference between a molecule of a compound and a molecule of an element is that in a molecule of an element, all the atoms are the same. For example, in a molecule of water (a compound), there is one oxygen atom and two hydrogen atoms. But in a molecule of oxygen (an element), both of the atoms are oxygen.

A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds. ... There are two main types of chemical bonds that hold atoms together: covalent and ionic/electrovalent bonds. Atoms that share electrons in a chemical bond have covalent bonds.

What is the difference between a compound and a molecule? A compound is a substance that is composed from two or more different elements. ... Molecules have molecular bonds. Nitrogen gas (N2) is a molecule because the bond between the nitrogen atoms is a molecular bond.

element - a basic substance that can't be simplified (hydrogen, oxygen, gold, etc...) molecule - two or more atoms that are chemically joined together (H2, O2, H2O, C6H12O6, etc...)

Molecules are groups of atoms forming a distinct substance. So, a molecular ion is an ion with a group of atoms. Much of the study of chemistry, however, involves looking at what happens when atoms combine with other atoms to form compounds. A compound is a distinct group of atoms held together by chemical bonds.

Two or more atoms that are bonded together. The atoms may or not be made from different elements. ... Molecules can be bonded from the same elements, whereas compounds can only combine if the elements are different.

A molecule refers to two or more elements that are covalently-bonded together. For example, in one mole of H2O there would be 6.022 x 10^23 molecules of H2O. A formula unit refers to the lowest whole number ratio (like an empirical formula) of a compound with an ionic bond.

The atoms in a molecule are joined by covalent bonds . The atoms always join in fixed ratios and molecules have a specific formula, eg H 2O or N 2. There are molecules of compounds (eg CH 4) and molecules of elements (eg O 2).

An atom is the smallest amount you can have of an element whereas a molecule is the smallest amount you can have of a compound. A compound is made of atoms.

Compounds contain two or more atoms and are held together by ionic bonds, whereas molecules are held together by covalent bonds. The atoms within a compound also must be different from eachother, whereas a molecule can consist of only one element.

The empirical formula of a compound gives the simplest ratio of the number of different atoms present, whereas the molecular formula gives the actual number of each different atom present in a molecule.

A molecule can be defined as the combinations of two or more atoms which are held together by chemical bonds. A molecule is the smallest portion of a substance which showcases all the properties of the substance.

1 Answer. A molecule is composed of two or more elements that are covalently bonded. A formula unit indicates the lowest whole number ratio of ions in an ionic compound.

Atoms of different elements can combine to make new substances. A molecule is formed when two or more atoms join together chemically. If atoms combine that are of two or more different elements, we call that a compound. All compounds are molecules, but not all molecules are compounds.

An atomic element would be an element composed of single unbounded atoms. A molecular element would be the smallest unit of a covalently bonded element that is capable of independant existence. A molecular compound would be the smallest unit of a covalently bonded compound that is capable of independant existence.

An atom is a particle of matter that characterizes a chemical element. It is the smallest part of ordinary matter. ... A compound is a substance that is made up of two or more different elements that are chemically joined, such as H2O,CO,NaCl . Note: All compounds are molecules, but not all molecules are compounds.

Every combination of atoms is a molecule. A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds.
