An isotope contains 11 protons, 10 electrons, and 12 neutrons.
what is the identity of the isotope?

Sodium

Explanation:

Sodium is a chemical element with the symbol Na, has an atomic number 11 (11 protons and 11 electrons) and atomic mass 23 u.

Isotope, is the term given to variants of the same chemical element. All isotopes of a chemical element have the same number of protons. So if an atom contains 11 protons, 10 electrons and 12 neutrons, that atom is a sodium isotope.

Sodium is very important, as it is present in the human body and also in daily food. It is the main homemade seasoning: sodium chloride (NaCl), better known as table salt. It is present in our body structure as follows: when it reaches its ionized form within our body, sodium becomes one of the main factors for osmotic regulation of blood, intercellular fluids and acid-base balance.
