Will two different isotopes of the same element have the same atomic number?

Will two different isotopes of the same element have the same atomic number?

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.

Why do two isotopes of an element have the same atomic number but different mass numbers?

Isotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2). Isotopes of a given element contain different numbers of neutrons, therefore, different isotopes have different mass numbers.

In what way are two isotopes of the same element different?

Two isotopes of the same element have the same number of protons in the nucleus, but differ in the number of neutrons. The nucleon number is equal to the total number of protons and neutrons in the nucleus.

In what way are two isotopes of the same element different explain why isotopes of the same element have the same chemical behavior?

– Isotopes of the same element have different numbers of neutrons, and therefore, different mass numbers and different atomic masses. Isotopes of the same element have the same number of protons and electrons. The electrons, not the neutrons, are responsible for an element’s chemical behavior.

Why do isotopes have the same properties?

Usually one or two isotopes of an element are the most stable and common. Different isotopes of an element generally have the same physical and chemical properties because they have the same numbers of protons and electrons.

What is the difference between chlorine 35 and chlorine 36?

(The mass number is the sum of the number of protons and neutrons in the nucleus of the atom.) These neutrons can cause additional fissions (producing a chain reaction), escape from the reactor, or irradiate nearby materials. The chlorine-35 remaining in the graphite moderator absorbed neutrons to become chlorine-36.

What is the use of chlorine 36?

[en] Chlorine-36 has been widely used for dating old groundwater. The 36Cl used for this purpose is produced in the atmosphere through the interaction of cosmic rays with argon atoms. The 36Cl then mixes with ordinary atmospheric chloride (mostly derived from the ocean).

What is the stable daughter product of chlorine 36?

Chlorine has two stable isotopes and one naturally occurring radioactive isotope, the cosmogenic isotope 36Cl. Its half-life is 301,300 ± 1,500 years. Cl decays primarily (98%) by beta-minus decay to 36Ar, and the balance to 36S….Chlorine-36.

Is calcium 42 stable or radioactive?

About Calcium-42 Carbonate Isotope Calcium 42 Carbonate (Calcium-42) is a stable (non-radioactive) isotope of Calcium. It is both naturally occurring and produced by fission.
