What is an isotope symbol?
These differing atoms are called isotopes.
To write the symbol for an isotope, place the atomic number as a subscript and the mass number (protons plus neutrons) as a superscript to the left of the atomic symbol.
The symbols for the two naturally occurring isotopes of chlorine are written as follows: 3517Cl and 3717Cl..
What 3 things must be the same for an atom to be an isotope?
Isotopes are atoms of an element with the normal number of protons and electrons , but different numbers of neutrons. Isotopes have the same atomic number, but different mass numbers. Isotopes can either be radioactive or non-radioactive.
How do you create an isotope?
This can be done by firing high-speed particles into the nucleus of an atom. When struck, the nucleus may absorb the particle or become unstable and emit a particle. In either case, the number of particles in the nucleus would be altered, creating an isotope.
What is the use of an isotope?
Radioactive isotopes have many useful applications. In medicine, for example, cobalt-60 is extensively employed as a radiation source to arrest the development of cancer. Other radioactive isotopes are used as tracers for diagnostic purposes as well as in research on metabolic processes.
Do all elements have isotopes?
All elements have a number of isotopes. Hydrogen has the fewest number of isotopes with only three. The elements with the most isotopes are cesium and xenon with 36 known isotopes. Some isotopes are stable and some are unstable.
Are all isotopes radioactive?
The nuclei of radioisotopes are unstable, so they constantly decay and emit radiation. In elements with more than 83 protons, all of the isotopes are radioactive.
What is an isotope easy definition?
noun Chemistry. any of two or more forms of a chemical element, having the same number of protons in the nucleus, or the same atomic number, but having different numbers of neutrons in the nucleus, or different atomic weights. … Isotopes of a single element possess almost identical properties.
How isotopes are written?
Isotopes are written in two different ways. They can be written using their symbol with the mass number (to the upper left) and atomic number (to the lower left) or the isotope name is written with a dash and the mass number. For example: Two naturally occurring isotopes of chlorine are chlorine-35 & chlorine-37.
What is another word for isotope?

Do Isotopes have the same atomic mass?
Isotopes are atoms with different atomic masses which have the same atomic number. The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.
Why do isotopes have the same properties?
All atoms of the same element have the same number of protons, but some may have different numbers of neutrons. … Different isotopes of an element generally have the same physical and chemical properties. That’s because they have the same numbers of protons and electrons.
How atomic mass is calculated?
For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu). By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.
What are 3 examples of isotopes?
Isotopes ExamplesCarbon-14. A naturally occurring radioactive isotope of carbon having six protons and eight neutrons in the nucleus. … Iodine-131. It is an isotope because it contains a different number of neutrons from the element iodine. … Tritium.
What causes isotopes to form?
Long story short, isotopes are simply atoms with more neutrons — they were either formed that way, enriched with neutrons sometime during their life, or are originated from nuclear processes that alter atomic nuclei. So, they form like all other atoms.
What are the 2 types of isotopes?
There are two main types of isotopes, and these are radioactive isotopes and stable isotopes.
What are isotopes examples?
The number of nucleons (both protons and neutrons) in the nucleus is the atom’s mass number, and each isotope of a given element has a different mass number. For example, carbon-12, carbon-13, and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13, and 14, respectively.
What is isotope short answer?
An isotope of a chemical element is an atom that has a different number of neutrons (that is, a greater or lesser atomic mass) than the standard for that element. The atomic number is the number of protons in an atom’s nucleus.
How do you figure out isotopes?
The mass number of an isotope represents the mass of the isotope’s protons and neutrons. Calculate the number of neutrons in an isotope, by subtracting the atomic number from the mass number. For example, carbon-12 has six neutrons, since the atomic number of carbon is six.
