What is an isotope short definition?
isotope, 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 behaviour but with different atomic masses and physical properties. Every chemical element has one or more isotopes.
What is an isotope GCSE?
Atoms of the same element must have the same number of protons , but they can have different numbers of neutrons . Atoms of the same element with different numbers of neutrons are called isotopes .
What are isotopes answer?
Isotopes are versions of the same element. They have the same number of protons and electrons as the element but different mass numbers and number of neutrons. The number indicates the isotope’s mass number.
What is isotopes in physics with example?
Isotope → Isotopes are atoms with the same number of protons, but differ in numbers of neutrons. Isotopes are different forms of a single element. Example – Carbon 12 and Carbon 14 are both isotopes of carbon, one with 6 neutrons and one with 8 neutrons.
How do you make 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 isotope example?
The definition of an isotope is an element with similar chemical make-up and the same atomic number, but different atomic weights to another or others. An example of an isotope is Carbon 12 to Carbon 13.
Which is the best definition of an isotope?
Science definitions for isotope. One of two or more atoms that have the same atomic number (the same number of protons) but a different number of neutrons. Carbon 12, the most common form of carbon, has six protons and six neutrons, whereas carbon 14 has six protons and eight neutrons.
Are there isotopes that have the same number of protons?
All isotopes of a given element have the same number of protons but different numbers of neutrons in each atom.
What does the superscript number on the left of an isotope mean?
The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses. The superscript number to the left of the element abbreviation indicates the number of protons plus neutrons in the isotope.
How is the total number of neutrons in an isotope determined?
For example, the uranium-235 isotope can be represented as 23592 U and the uranium-239 isotope can be represented as 23992 U. The total number of neutrons in the nucleus of an isotope can be determined by subtracting the atomic number of the element from the mass number of the isotope.
