How do scientists determine isotopes of elements?
Isotopes have different atomic masses. The average atomic mass of an element is a weighted average calculated by multiplying the relative abundances of the element’s isotopes by their atomic masses and then summing the products. The relative abundance of each isotope can be determined using mass spectrometry.
What determines which isotope an element is?
Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons. The number of protons in a nucleus determines the element’s atomic number on the Periodic Table. Every element has its own number of isotopes.
How do scientists define isotopes?
An isotope is one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behavior but with different atomic masses and physical properties.
What causes an element to have isotopes?
Isotopes can either form spontaneously (naturally) through radioactive decay of a nucleus (i.e., emission of energy in the form of alpha particles, beta particles, neutrons, and photons) or artificially by bombarding a stable nucleus with charged particles via accelerators or neutrons in a nuclear reactor.
How do you tell which isotope is most abundant?
To determine the most abundant isotopic form of an element, compare given isotopes to the weighted average on the periodic table. For example, the three hydrogen isotopes (shown above) are H-1, H-2, and H-3. The atomic mass or weighted average of hydrogen is around 1.008 amu ( look again at the periodic table).
How do isotopes of an element differ?
Isotopes. An isotope is one of two or more forms of the same chemical element. Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope a different atomic weight.

What does it mean when an isotope is more abundant?
The periodic table’s atomic mass is the AVERAGE weight of ALL its isotopes. If one isotope is MORE abundant than the others, the average will be closest to the mass of that isotope.

How do isotopes of a given element differ How are isotopes of a given element similar?
By definition, isotopes of a given element have the same number of protons and electrons, but differ in the number of neutrons. This causes a difference in the mass number (protons + neutrons) as well. Neither the number of protons nor the number of electrons changes with different isotopes of the same element.
How do isotopes of a given element similar?
Isotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2). Isotopes of a given element contain different numbers of neutrons, therefore, different isotopes have different mass numbers.
