What is an isotope easy answer?

What is an isotope easy answer?

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.

What are isotopes Mcq?

Explanation: Isotopes are defined as the elements having same atomic number but they differ in their mass number and chemical characteristics. Explanation: the U-235 isotope of uranium is easily and readily fissionable.

What is isotope quizlet?

Isotope. any of two or more versions of a chemical element, having the same number of protons in the nucleus, or the same atomic number, but having different numbers of neutrons in the nucleus, or different atomic masses. Mass.

What is the isotope formula?

This can be done through the following formula: Average Atomic Mass = (Mass of Isotope 1 x Fractional Abundance of Isotope 1) + (Mass of Isotope 2 x Fractional Abundance of Isotope 2) + …… The average atomic mass has been calculated in this fashion and can be found under every symbol in the periodic table.

What are isotopes Mcq Sanfoundry?

Isotopes have the same number of protons. Explanation: The isotopes have same number of protons but different number of neutrons in their nucleus. Hydrogen has three isotopes depending on the number of neutrons – 0, 1 or 2. 3.

Are isotopes the same element?

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.

What is meant by isotopes in chemistry?

An isotope is 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 behavior but with different atomic masses and physical properties.

How are isotopes defined quizlet Edgenuity?

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.

What are isotopes give example?

Isotope definition U-235, U-238, and U-239 are three isotopes of uranium. 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.

What are the 2 types of isotopes?

There are two main types of isotopes: stable and unstable (radioactive). There are 254 known stable isotopes. All artificial (lab-made) isotopes are unstable and therefore radioactive; scientists call them radioisotopes. Some elements can only exist in an unstable form (for example, uranium).

What are 5 examples of isotopes?

Examples of radioactive isotopes include carbon-14, tritium (hydrogen-3), chlorine-36, uranium-235, and uranium-238. Some isotopes are known to have extremely long half-lives (in the order of hundreds of millions of years). Such isotopes are commonly referred to as stable nuclides or stable isotopes.
