Difference between an atom and a molecule?

Answer 1

An atom consists of a nucleus (containing one or more protons and zero or more neutrons) and some number of electrons. Atoms have the same number of protons and electrons, because otherwise, you would have an ion.

A molecule consists of two or more atoms bonded together.

Atoms are single units of elements.

Molecules are agglomerations of two or more atoms (of the same or different elements). A molecule is the smallest particle of a chemical compound. Molecules are formed by atoms in a multitude of different arrangements.

- Most atmospheric oxygen forms diatomic molecules (O2), but also ozone (O3)

- One molecule of water has one atom of hydrogen and two atoms of oxygen. So-called heavy water contains deuterium, which is hydrogen that has neutrons.

- A molecule of potassium permanganate have one atom of potassium, one atom of manganese and four atoms of oxygen which give the molecule the structural formula KMNO4
An atom(element) can not be broken down by chemical processes except for radioactive decay. A molecule is made up of atoms ie H2O (water) is two hydrogen atoms and one oxygen atom. H2O can be broken down into the hydrogen atom and oxygen atom but no further.

Answer 2

An atom is the most basic level of matter and is found in both living and nonliving things. Its name literally means unable to divide. It is made up of protons positive particals, nuetron netral particals and electrons the much smaller negitive particals. In an atom the protons and neutrons are in the center and the elctrons circle the atom in the electron clould. The molecule is a compound that's made of two or more atoms and is formed by a covalent or sharing bond between the electrons of two or more types of atoms. The difference is that the atom is smaller and is the most basic unit while the molecule is slightly more complex. Take the most common compound, water it is made of two hydrogen atoms and one oxygen atom the larger oxygen atom shares some electrons with the two smaller hydrogen atoms.

Answer 3

An atom is the smallest unit of matter that retains the properties of an element, consisting of a nucleus made up of protons and neutrons surrounded by electrons. A molecule, on the other hand, is a group of two or more atoms held together by chemical bonds. Thus, while atoms are individual particles, molecules are formed when atoms chemically bond with each other.

Answer 4

an atom is defined as the smallest part of an element which can exist.Unlike an atom a molecule is made up of two or more atoms chemically combined

Answer 5

The difference? One exists and the other does not.

There is no such thing as an atom of water. Water is a molecule made of two hydrogen atoms and one oxygen atom.

Answer 6

an atom is the smallest unit of matter, where as a molecule is one or more atoms bonded together

Answer 7

A molecule of oxygen has two oxygen atoms.

A molecule of water has only one oxygen atom, but it also has two hydrogen atoms which together form a sort of "V" shape.

Answer 8

The difference is that an atom is the smallest of the small and they are PARTS OF molecules. Molecules are the second smallest particle, because atoms are the smallest.

Answer 9

nothing if i am not mistaken
