What is difference between atom and ions?
Atoms where the electrons and protons are not equal are called ions. Ions are charged particles. They can be either positively charged ions or negatively charged ions….

How do you know if an atom is an ion?
If an atom has the same number of protons and electrons, it is electronically neutral. However, if the total number of electrons does not equal the number of protons, the atom has a net electrical charge. Any atom or molecule with a net charge, either positive or negative, is known as an ion.
Why does an atom become an ion?
An atom becomes an Ion (a) if it gains one or more electron(s) or (b) if it loses one or more electron(s). When it gains electrons it becomes negatively charged and is called an anion. When it loses electron(s) it becomes positively charged and is called a cation.
What are ions examples?
An ion is an atom or a group of atoms in which the number of electrons is different from the number of protons. If the number of electrons is less than the number of protons the practical is a positive ion, also called a cation. Ex : sodium ion Na+ , chloride ion cl- , and oxide ion O2 -.
What is the charge of an ion?
Since the electric charge on a proton is equal in magnitude to the charge on an electron, the net electric charge on an ion is equal to the number of protons in the ion minus the number of electrons.
What is a positively charged atom called?
cation
The atom that has lost an electron becomes a positively charged ion (called a cation), while the atom that picks up the extra electron becomes a negatively charged ion (called an anion).
What is a charge of an atom?
The charge of an atom is the number of protons minus the number of electrons. Usually, these two numbers are equal, so the atom is neutral (charge of zero). Answer 8: An atom is defined as having the same number of electrons (negative charge), protons (positive charge) and neutrons (no charge).
