If asked "What is an isotope ?" in GCSE Chemistry, a more detailed answer is required using one of the definitions below: Definitions of an isotope: Isotopesare atoms of thesameelementthat have thesamenumber of protons butdifferentnumbers of neutrons. ...
What is a proton ? What is a neutron ? What is an electron ? What is an Atomic Number ? What is a Mass Number (of an atom)? What is Relative Atomic Mass? What is an isotope ? What is a molecule ? Elements Mixtures & Compounds Elements, Mixtures and Compounds What is a chemical ...
And while stars are very far apart and long-lived, over Earth's lifetime, even a few nearby stars have exploded with a nearly Earth-shattering kaboom. One piece of evidence for a nearby supernova comes from an unstable isotope of iron whose only earthly traces come from grains of sediment...
What is the electronegativity of fluorine? What is a natural isotope? Which atom is an isotope of 84Be? What is the atomic number of scandium? What is the atomic number for californium? What is a radioactive isotope? What is a stable isotope?
crystal layers, with each layer recording the isotopic age of an event, thus tracing the progress of the a quantity of metamorphic occasions. All elements on the Periodic Table of Elements (see Chapter 3) include isotopes. An isotope is an atom of a component with a unique number of ...
An isotope is simply an atom with a different number of neutrons that we'd normally expect to find. Artwork: Carbon-12 and carbon-14 are both isotopes of carbon: different variations that have different numbers of neutrons (blue). Carbon-14 has two more neutrons (yellow) than carbon-12, ...
Distinguish between the atomic number and the mass number of an element. What is an isotope? Identify one element from the periodic table and explain its role in the human body (either alone or as part of a molecule). Is it something we need to survive? If so, is it found in any fo...
WHAT IS ISOTOPE SEASONALITY?O) variability in fossil teeth, invertebrate shells, and speleothems have been used to infer changes in climate seasonality through time. During their accretionary growth, these substrates record seasonal fluctuations in environmental water δBOWEN, Gabriel J...
Remember, an isotope is a form of a chemical element that has the same number of protons in its atomic nucleus but a different number of neutrons. The most common isotope of helium on Earth is helium-4, which does not have any known or potential uses as an energy source. Helium-3, in...
What is the most common isotope of argon? Isotopes Explained: Elements are classified by the number of protons in the nucleus of the atom. However, there is no set rule for how many neutrons can be in the atom's nucleus. Because this number can vary, we classify the different, naturally...
