A molecule is neutral, an ion has an electrical charge.


What are the differences between molecule and molecular ion?

A molecular ion is a type of ion that either has less or more electrons than it has protons. A polar molecule is a molecule that has positive charges near its center and negative charges outside that center.


Is a ion a neutral group of atoms?

An ion is an atom or molecule which has lost or gained a number of electrons, so that it becomes either negatively or positively charged. Ions are not neutral.


How are molecules and poly-atomic ions unlike?

A molecule is neutral, an ion has an electrical charge.


What is the energy needed to remove an electron from a negative ion to form a neutral atom or molecule?

The energy needed to remove an electron from a negative ion to form a neutral atom or molecule is called the electron affinity. It represents the energy change when an electron is added to a neutral atom or molecule to form a negative ion. The higher the electron affinity, the greater the energy needed to remove an electron.


What is a charged molecule?

You think to a ion (anion or cation).


Is hydroxide ion a anion or cation?

The hydroxide ion (OH-) is an anion because it carries a negative charge. It is formed when a hydrogen ion (H+) is removed from a water molecule (H2O).

What is an example of an ion?

An ion is an atom or molecule which has either gained an electron or lost one so that it is no longer neutral.
