Write 1 difference between the
A. composition of atoms and molecules
B. charge on an atom and an ion
Answers
A
Composition of the Atom. The atom consists of a tiny nucleus surrounded by moving electrons. The nucleus contains protons, which have a positive charge equal in magnitude to the electron's negative charge.
Composition of molecules. A molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. ... The atoms of certain elements readily bond with other atoms to form molecules. Examples of such elements are oxygen and chlorine
charge on atom. An atom consists of a positively charged nucleus surrounded by one or more negatively charged particles called electrons. The number of protons found in the nucleus equals the number of electrons that surround it, giving the atom a neutral charge
B
An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
