An isotope depends on the number of neutrons in the atom. If you consider various isotopes of a particular element, the proton number does not change.
Examples:
Carbon 12: 6n, 6p
Carbon 13: 7n, 6p
Hydrogen 1 (protium): 1p
Hydrogen 2 (deuterium): 1n, 1p
There are many elements that have only one naturally occurring isotope. When you get to transuranic elements the elements all have no naturally occurring isotopes. But all elements have isotopes, they just have to be created, maybe in a nuclear reactor or particle accelerator or a supernova explosion.
No.
No elements have the same average mass, but some isotopes are the same mass as other elements, For example Carbon-13 (an isotope of carbon) has the same mass as nitrogen-13 (which is also an isotope of nitrogen).
No. Deuterium is not an element in and of itself. It is an isotope of hydrogen.
No, bicarbonate is not an isotope. Bicarbonate refers to the chemical compound with the formula HCO₃⁻, which is an anion formed from carbonic acid. An isotope, on the other hand, refers to different forms of the same element that have the same number of protons but different numbers of neutrons. Bicarbonate can contain isotopes of its constituent elements, but it itself is not an isotope.
6C13 isotope. The element is carbon
By striking it with neutrons.
Isotope
Mono isotopic elements are stable isotope of an element.From 80 isotopic elements there are 26 radioactive elements discovered up till now.These mono isotopic may or may not be radioactive if they are radioactive they have halve lives.
All chemical elements (excepting the isotope 1H) contain neutrons.
The number of neutrons will vary for every isotope of an atom and is not possible to generalize for all the elements.

But all elements have isotopes, they just have to be created, maybe in a nuclear reactor or particle accelerator or a supernova explosion.
Isotopes are very important part of calculations in chemistry. They are different elements of same atomic number.
This is an element (more exactly an isotope) which is not radioactive.
No.
yes. but only for a given isotope
No elements have the same average mass, but some isotopes are the same mass as other elements, For example Carbon-13 (an isotope of carbon) has the same mass as nitrogen-13 (which is also an isotope of nitrogen).
