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 is the difference between two isotopes of an element give an example?
E.g. carbon, oxygen, hydrogen etc. Isotopes are elements with different masses. ... The difference between C12 and C13 is the amount of neutrons , both have 6 protons where C12 have 6 neutrons whereas C13 have 7 neutrons. So isotopes have the same amount of protons but with different amounts of neutrons.
What is the difference between two isotopes of an element Brainly?
Isotopes of an element will contain the same number of protons and electrons but will differ in the number of neutrons they contain . In other words, isotopes have the same atomic number because they are the same element but have a different atomic mass because they contain a different number of neutrons.
What are 2 isotopes of the same element?
Two atoms that contain the same number of protons but different numbers of neutrons are isotopes of the same element. Their masses are different, but they react the same way chemically.
Why do elements have different isotopes?
All oxygen atoms on Earth (and Universe) have the same number of protons (and electrons), But they can have different numbers of neutrons. Different isotopes of the same element have different masses. ... Therefore, elements have different isotopes due to the varying number of neutrons found in the nucleus of the atom .
What are 2 examples of isotopes?
For example, carbon-12, carbon-13, and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13, and 14, respectively. The atomic number of carbon is 6, which means that every carbon atom has 6 protons so that the neutron numbers of these isotopes are 6, 7, and 8 respectively.
What do the numbers of isotopes mean?
Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons . ... The superscript number to the left of the element abbreviation indicates the number of protons plus neutrons in the isotope.
What 3 things do isotopes of the same element have in common?
Isotopes of an element share the same number of protons but have different numbers of neutrons . Let's use carbon as an example. There are three isotopes of carbon found in nature – carbon-12, carbon-13, and carbon-14. All three have six protons, but their neutron numbers – 6, 7, and 8, respectively – all differ.
How is atomic mass calculated?
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons . If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
What sets atoms of one element apart?
The number of protons in an atom is the defining feature of an atom. It's what makes one element different from another. The number of protons in an atom is called its atomic number. ... All the elements in the universe are arranged according to their atomic number in the periodic table.
What are 3 examples of isotopes?
Isotope Examples
The isotopes of hydrogen are hydrogen-1 (protium, which is a stable isotope), hydrogen-2 (deuterium, which is another stable isotope), and hydrogen-3 (tritium, which is a radioisotope). Uranium-235 and uranium-238 are two isotopes of uranium.
Why do isotopes happen?
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 reactors.
How do you identify isotopes?
Isotopes are identified by their mass , which is the total number of protons and neutrons. There are two ways that isotopes are generally written. They both use the mass of the atom where mass = (number of protons) + (number of neutrons).
Is carbon 13 a radioactive isotope?
FIVE isotopic forms of the element carbon are known, having atomic weights ranging from 10 to 14. Two of them, C 12 and C 13 , exist stably in Nature, while the others are radioactive , and are known to us only through their production in various nuclear reactions.
What are the types of isotopes?
There are two main types of isotopes, and these are radioactive isotopes and stable isotopes . Stable isotopes have a stable combination of protons and neutrons, so they have stable nuclei and do not undergo decay.
Can an atom have more than 1 isotope?
Molar Atomic Masses of Elements
The molar mass of an atom is simply the mass of one mole of its identical atoms. However, most of the chemical elements are found on earth not as one isotope but as a mixture of isotopes, so the atoms of one element do not all have the same mass.
