What isotopes are atoms of the same elements with different number of?

Isotopes are atoms of the same elements with different number of neutrons.


What do most elements contain a mixture of?

Most elements contain a mixture of isotopes, which are atoms of the same element with different numbers of neutrons. Isotopes can have different properties but behave similarly in chemical reactions due to their identical number of protons.


What are elements with identical number for protons and different number of neutrons called?

The answer you are looking for is "isotopes" HOWEVER, please note you CAN NOT HAVE 2 elements with the same number of PROTONS. This is because the number of protons DEFINES an element. Isotopes are the SAME element but with differing numbers of neutrons.


What relationships of isotopes and elements?

An isotope is an atom; a chemical element may be formed from one or more isotopes having the same number of protons and electrons but with different number of neutrons.


Why the mass number of the same atom of an element is not constant?

Since you have isotopes of elements. Isotopes are elements with different number of neutrons hence why the different atomic masses for the same elements.


What do you think nuclear chemists mean when they say that 8 20 and 50 are magic numbers for isotopes?

It is simply that among period 2 elements, oxygen (8) is one of the elements which has the largest number of isotopes, among period 4 elements, calcium (20) has the largest number of isotopes, and among period 5 elements, tin (50) has the largest number of isotopes. In fact tin has the largest number of isotopes overall.


How do isotopes form?

During some radioactive explosion/exposure the atoms combine and if they stay stable they from with extra amounts of protons. Isotopes are when two or more elements have the same number of protons, but different number of neutrons.


Isotopes of uncharged elements have different numbers of?

Isotopes differ in the number of neutrons they possess.


Which elements have different isotopes?

Many elements have different isotopes: 1) Carbon - Carbon 12, Carbon 14 2) Hydrogen - Protium, Deuterium, Tritium 3) Chlorine - Chlorine 35, Chlorine 37 etc


What isotopes of uncharded elements have different numbers?

The atomic number of the isotopes of an element is identical; the mass number is different.
