An isotope is one of two or more species of atoms of a chemical element with the same atomic number (same number or protons in the nucleus) and position in the periodic table and nearly identical chemical behavior but with different atomic masses and physical properties.
What are the isotopes of an atom quizlet?
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. The different isotopes of an element have identical chemical properties.
Which atoms are isotopes of the same element quizlet?
Isotopes are atoms of the same element that have the same number of protons but a different number of neutrons. Therefore, isotopes have the same atomic number (number of protons) but a different mass number (number of protons plus number of neutrons).
What do isotopes have in common quizlet?
What do isotopes of an element have in common? How do they differ? The have the same atomic number (protons) but different number of neutrons causing the isotopes to having different atomic masses.
What is an isotope How are isotopes used quizlet?
What is an isotope and how are they used in biological research and medicine? Isotopes are elements that can exist in different forms. Radioactive isotopes are isotopes with a spontaneously decaying nucleus, and are used in medicine and biological research. They are used for biological research in carbon dating.
What makes an atom an isotope?
Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.
How are isotopes defined quizlet Edgenuity?
What is an isotope? Atoms of the same element with the same number of protons, but different number of neutrons.
Are isotopes atoms of the same element?
Why do atoms have different isotopes?
Neutrons exist to stabilize the nucleus – without them, the nucleus would consist of nothing but positively-charged protons in close proximity to one another. Because there are different ways of stabilizing the protons, there are different isotopes.
Why are there isotopes for various atoms?
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 do isotopes have?
Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons. The number of protons in a nucleus determines the element’s atomic number on the Periodic Table. For example, carbon has six protons and is atomic number 6.
How do atoms become isotopes?
The number of protons determines an element’s atomic number and is used to distinguish one element from another. The number of neutrons is variable, resulting in isotopes, which are different forms of the same atom that vary only in the number of neutrons they possess.
What do isotopes have the same number of?
The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. Different isotopes of the same element have different masses.
How do the isotopes of an element differ?
Isotopes of the same elements differ in their mass number. Isotopes are those elements have the same protons but differs from their neutrons. That is why it differs in their mass number because the mass number is the sum of protons and neutrons.
What do isotopes have in common?
All isotopes of the same element share a common number of protons and electrons, though they vary in their relative numbers of neutrons. All isotopes of a given element are chemically identical, and they form bonds with other elements in the same way regardless of their neutron count or intrinsic stability.
