Q

ions

A

The loss or gain of electrons allows the atom to acquire an electric charge, transforming itself into an ion . If the electric charge is positive, it is called a cation; if it is negative, it is called an anion. It is concluded that the non-ionized atoms are electrically neutral.

Q

neutral atoms

A

An electrically neutral atom contains bound electrons equal in number to the protons in the nucleus. … In chemical terms, if a neutral atom loses one or more electrons, it has a net positive charge and is known as a cation.

Q

atoms vs ions

A

Atoms vs. Ions. Atoms are neutral; they contain the same number of protons as electrons. By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion.

how many atoms does an ion have

A

Ions consisting of only a single atom are termed atomic or monatomic ions, while two or more atoms form molecular ions or polyatomic ions.
