What is the meaninq of two isotopes stable and unstable isotopes?
Isotopes are atoms of the same element that have the same number of protons, but different numbers of neutrons, and therefore different masses. Unstable isotopes are radioactive and undergo radioactive decay of their nuclei, while stable isotopes do not undergo radioactive decay.
In 1938 scientists discovered that bombarding large atomic nuclei with neutrons causes the nuclei to split into smaller nuclei and release energy. What was created as a result of this discovery?
Two new isotopes are produced by fission.
Does all atoms have neutrons in their nuclei?
No, not all atoms have neutrons in their nuclei. Some atoms, known as isotopes, can have varying numbers of neutrons in their nuclei while still belonging to the same element. For example, hydrogen has three isotopes: protium (no neutrons), deuterium (one neutron), and tritium (two neutrons).

Which elements has 2 neutrons?
For the most part Helium has two neutrons, the exception is with isotopes.
What happens where two elements have the same atomic number?
When two elements have the same atomic number, it means they are isotopes of each other. Isotopes have the same number of protons but different numbers of neutrons in their nuclei. This results in subtle differences in their atomic mass and stability.

When a pair of hydrogen isotopes is fused is the mass of the product nucleus more or less the sum of the masses of the two hydrogen nuclei?
Because of conservation of matter the nucleus would weigh the same as the sum of the two isotopes.
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.
Comparison of fission fusion and transmutation?
Fission is the splitting of heavy nuclei, mostly Uranium235 but also Plutonium 239, which is made to happen in nuclear fission reactors, and releases energy. Transmutation of elements occurs in this process as when the heavy nucleus splits, two lighter nuclei of other elements such as caesium, strontium, iodine, are formed, these are the fission products. Fusion is the joining together of two nuclei, the ones being experimented with being deuterium and tritium, both isotopes of hydrogen. These transmute to helium during fusion.
How many atoms of the same elementdiffer from one anotherwhat do you call them?
Most elements exist n two or more forms with differing masses because of differences in the numbers of neutrons in their nuclei. These different forms are called "isotopes" of one another.
How do scientist tell the different between two isotopes of the same element?
scientists Can tell the difference between two isotopes of the same element because, isotopes of the same elements always have the same number of protons.
Chlorine has two isotopesstate one way in which atoms of the two isotopes are the same?
The two isotopes of chlorine are the same in that they have the same number of protons, which is the atomic number. The neutral atoms of each isotope also have the same number of electrons as protons. They differ in the number of neutrons.
What do two different neutral Isotopes have the same elements in common?
The proton and electron number are equal for all isotopes of the same specific element.
Which two notations represent atoms that are isotopes of the same element?
The two notations represent atoms that are isotopes of the same element is 121 Sn and 119 Sn. The atomic mass of an element is defined as the weighted average mass of that elements naturally occurring isotopes.
