What are Isotopes?

Question

I've been asked to define isotopes, note these, show their details or note if there are not any isotopes for my element Titanium.

Answer 1

Atoms have balanced electrons and protons, right?

An isotope is just an atom with more electrons than protons or vice versa.

Answer 2

Isotopes are any of the different chemical species of a chemical element each having different atomic mass (mass number). Isotopes of an element have nuclei with the same number of protons (the same atomic number) but different numbers of neutrons. Therefore, isotopes have different mass numbers, which give the total number of nucleons—the number of protons plus neutrons.

Answer 3

Isotope: An atom with a fewer or greater number of electrons than protons.

All Isotopes have either a positive or negative charge.

and yes, titanium has at least 20 isotopes.

Answer 4

Isotope literally means same (iso) place (topes) in the periodic table of elements.  All isotopes of a given element have the same number of electrons and protons (atomic number) and enter into the same chemical reactions.  The isotopes differ in the number of neutrons (atomic weight) which do no affect chemical reactions.

Answer 5

Consider this: Every atom has a set of protons, electrons and neutrons. Protons and neutrons lie in the nucleus. Total number of protons and neutrons of an atom is known as the mass number.

Atoms of same element will have the same number of protons. But different atoms of the same element may have different number of neutrons.

Such atoms are known as isotope (which vary in the number of neutrons)

Isotope may be defined as  - Atoms which have the same atomic number but different mass number.

E.g. Carbon - There are 2 varities, Carbon atom with mass number 12 and Carbon atom with mass number 14.

Chlorine - Cl with 35 and Cl with 37.

Coming to Titanium, ALL elements have isotopes. Though it may not be stable / abundant.

Actually mass number of an element is calculated by taking into consideration the different mass number variations of its atom and its abundance.

Formula is - [Mass Number = M1*(% abundance) + M2*(% abundance) + M3*(% abundance)+.....]/100
