What is an ion of an atom?

What is an ion of an atom?

Ion, any atom or group of atoms that bears one or more positive or negative electrical charges. Positively charged ions are called cations; negatively charged ions, anions.

What’s the difference between ion and isotope?

Isotopes are atoms that have the same number of protons but different numbers of neutrons. An ion is an atom or molecule with a positive or negative charge.

What is an ion give two 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 difference between ion and isotope?

What’s the difference between an ion and an isotope?

Isotopes are versions of a particular element that have different numbers of neutrons. Ions are atoms (or molecules) that have lost or gained electrons and have an electrical charge. Isotopes involve neutrons.

How are the isotopes of an atom established?

In an atom, there are different numbers of protons and neutrons. Its chemical element is established by the number of protons while the isotope of the element is established by the number of neutrons that it has.

Which is the most abundant isotope of an element?

Isotopes of an element have the same number of protons, but different numbers of neutrons in their nuclei. Isotopes of an element have: All hydrogen atoms contain one proton (and one electron), but they can contain different numbers of neutrons. Hydrogen-1 is the most abundant isotope of hydrogen.

What makes an ion different from an atom?

Ions are different from the atom, because of the number of electrons. Ions can have more or less electrons than the corresponding atom. • Ions are charged species, but isotopes are neutral.
