What is the correct statement about isotopes?
Isotopes of only heavier elements are radioactive in nature as they have large difference in the number of protons and neutrons. Thus, we can conclude that the statement isotopes of the same element have the same atomic number but differ in their atomic masses, is correct.
Which statement best describes why electrons are typically not included?
The mass of the atom is measured as the number of protons and neutrons in the nucleus of an atom. Since electrons are outside the nucleus, they are not counted to know the mass. The correct answer is d = Electrons are outside the nucleus.
Do Isotopes have the same chemical properties?
Atoms of the same element that differ in their numbers of neutrons are called isotopes. Different isotopes of an element generally have the same physical and chemical properties because they have the same numbers of protons and electrons.
How do different isotopes affect the properties?
1 Answer. Different isotopes have different numbers of neutrons in their nuclei. Having a different number of neutrons does not affect either one of these properties, so isotopes of an element will behave (chemically) the same. However, the greater mass of a heavier isotope does provide some useful differences.
How do you know if an element is an isotope?
Isotopes are simply specifying the number of neutrons and protons (together called nucleons) in the atom. So, Carbon-12, which has an atomic mass number of 12, has 6 neutrons (12 nucleons – 6 protons = 6 neutrons).
How do you label an isotope?
Isotopic labeling (or isotopic labelling) is a technique used to track the passage of an isotope (an atom with a detectable variation in neutron count) through a reaction, metabolic pathway, or cell. The reactant is ‘labeled’ by replacing specific atoms by their isotope.
Why is isotope labeling important?
Isotope labeling has been used for many years to study metabolic fluxes and determine the structure of metabolic pathways and networks. Stable isotopes have been used with MS for several decades by pharmacologists and toxicologists as internal standard (IS) to enable absolute quantification of drugs and metabolites.
Why is isotopic labeling important?
Isotopic labeling plays an indispensable role in structure determination of proteins and other biomacromolecules using solidstate NMR. It not only enhances the NMR sensitivity but also allows for site-specific interrogation of structures and intermolecular contacts.
