No, Gold and several other elements have only one stable isotope, Promethium & Technetium as well as all elements heavier than Bismuth have no stable isotopes.
No. Gallium is an element. The element Gallium has two naturally occuring stable isotopes (69Ga and 71Ga) and abpout 29 unstable isotopes.
Most elements - metals and non-metals - have both stable and radioactivie isotopes. If an element is a type of atom, an isotope is something like a "sub-type". Two isotopes of the same element have the same number of protons, but a different number of neutrons.Most elements - metals and non-metals - have both stable and radioactivie isotopes.

Every atom of the same element is also categorized by its number of neutrons. An atom with a certain number of neutrons is an "isotope." Two atoms of the same element (same quantity of protons) can be different isotopes (different quantity of neutrons). Some isotopes are unstable, so most stable isotopes of an element are withing a range of a few numbers. For example, stable isotopes of carbon are Carbon-12 and Carbon-13.
Isotopes are atoms of the same element with different numbers of neutrons. Stable isotopes have a balanced number of protons and neutrons, meaning their nuclei do not decay over time. Unstable isotopes, also known as radioactive isotopes, have an imbalance of protons and neutrons, causing their nuclei to decay and emit radiation over time.
Two stable ones, 10 & 11. Several unstable.
A neutral (uncharged) atom has the same number of protons and electrons. Isotopes of an element may have several stable isotopes with various numbers of neutrons.
Sodium-23 and Sodium-22 are two isotopes of sodium. Na-23 is the only stable isotope of Sodium. Na-22 is one of the two isomers (the other of which is Na-24).
Two different isotopes of an element have different numbers of neutrons. That's what an isotope is. So, no, isotopes of an element can not have the same number of neutrons.
Nitrogen has two stable isotopes: N-14 and N-15 and 14 radioactive isotopes.
scientists Can tell the difference between two isotopes of the same element because, isotopes of the same elements always have the same number of protons.
Isotopes
This question is misguided. Atoms do not have isotopes. In a sample of an element there are many atoms. They will all have the same number of protons in their nuclei, that's what makes them the same element. Individual atoms may have different numbers of neutrons, if this happens they are called isotopes. For instance in silver, all the atoms have 47 protons, but some of them have 60 neutrons and some have 62. We say that silver has two stable isotopes. Perhaps your question should be 'Do all atoms of the same element have the same number of neutrons?'
