An isotope is a form of an element. Isotopes (forms of an element) occur when an atom/s of a single chemical element gains or loses 1 or more neutrons.

Eg.. the first isotope "Hydrogen-1" or "Protium" hydrogen has 1 proton in the centre of the atom or nucleus, and 1 electron going around on the outside, isotope two "Hydrogen-2" or "Deuterium" Hydrogen, has 1 proton AND 1 neutron in the nucleus and 1 electron, and isotope three is "Tritium" Hydrogen that has 1 proton, 2 neutrons and 1 electron. The number of protons always stays the same, it's the number of neutrons that determines the form of an element or in other words the isotope.

12C and 14C are.1isomers 2isotopes 3free radicals 4ions 5allotropes?

12C and 14C are isotopes, meaning they are atoms of the same element with different numbers of neutrons in their nuclei. Isotopes have the same number of protons but different numbers of neutrons.


What term describes isotopes with an unbalanced number of neutrons?

Radioisotopes are isotopes that have an unbalanced number of neutrons, leading to instability and eventual decay. This instability results in the emission of radiation as the nucleus seeks to become more stable.


Do most elements occurs a mixture of two or more isotopes on nature?

For elements the correct term is atomic weight.For isotopes the correct term is atomic mass.The atomic weight is determined considering the isotopic composition of an element and the atomic mass of each isotope.


What term is used for atoms of the same element that differ in the number of neutrons?

I believe you're referring to atoms having the same number of protons, but differing numbers of neutrons. These atoms are called isotopes of one another.The word comes from the Greek for "at the same place," because even though the atoms have different masses they belong at the same place in the periodic table.


The various atomic weights of the same element are called?

Atoms of the same element with different atomic masses are known as isotopes. Isotopes differ only by the number of neutrons present in the nucleus of the isotopes. The number of protons is the same for all isotopes of an element (because if there were different numbers of protons, then the atoms would not be of the same element).

What is the term for atoms of the same element that differ in their mass numbers?

We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
