Isotope can be referred to as the different versions of the SAME ELEMENT. Such as Chlorine has isotopes of Chlorine - 35 and Chlorine - 37. This will just cause the difference in mass numbers because of the difference in neutrons. Chlorine -35 has 17 protons, 17 electrons and 18 neutrons making it to have a mass number of 35 and Chlorine - 37 has 17 protons, 17 electrons and 19 neutrons making it to have a mass number of 39. Some isotopes can be used in normal chemical reactions but some cannot.

How do the 2 sodium isotopes shown in the model differ from each other?
The number of neutrons is different.
How will the modern periodic table be disturbed if isotopes of an element are discovered now?
The periodic table would be disturbed only if isotopes of a new element are discovered, because a periodic table is based on order of atomic number, not atomic mass. If new isotopes of a previously known element were discovered, the atomic mass shown in the periodic table might be changed, but this is very unlikely because the atomic masses shown in a periodic table are based on the naturally occurring distribution of isotopes, and any newly discovered isotopes would probably occur only in very small fractions of the total.
Is lithium-6 more reactive than lithium-7?
Typically, isotopes are chemically identical. In other words, their reactivities should be the same. It has, however, been shown that some organisms are able to concentrate certain isotopes of some elements, though it is not understood how this is done.
Atoms of same chemical element that have different atomic mass are known as?
Isotopes. They differ in the number of neutrons in the nucleus.
Is it possible for two atoms of the same element to have different chemical properties?
Yes. In the case of isotopes of water. An H2O ice cube is shown to float in a beaker of liquid water, while an ice cube of D2O (heavy water) is shown to sink in liquid water.
How are isotopes placed in the periodic table?
Isotopes and their prevalence are not shown on the periodic table. Instead, the atomic weight shown for each element is an average of the atomic weights of all naturally-occurring isotopes (calculated from percentages occurring on Earth).
How do the 2 sodium isotopes shown in the model differ from each other?
The number of neutrons is different.

What is the weighted-average mass of all the known isotopes for an element?
The known weighted-averagemass of all the naturally occurring* isotopes for an element is the atomic mass of the element.____________________*This is not the same as "all the known isotopes", becausemost elements have known isotopes that are not naturally occurring.
What is the weighed-average mass of all the known isotopes for an element called?
Average Atomic Mass, or Atomic Weight of an element (the one shown on the Periodic table).
Is lithium-6 more reactive than lithium-7?
Typically, isotopes are chemically identical. In other words, their reactivities should be the same. It has, however, been shown that some organisms are able to concentrate certain isotopes of some elements, though it is not understood how this is done.
Atoms of same chemical element that have different atomic mass are known as?
Isotopes. They differ in the number of neutrons in the nucleus.
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.
How are radioactive isotopes different from isotopes?
Both isotopes and radioactive isotopes are pretty much the same but radioactive isotopes are better because it can be used to make medicine.
Is it possible for two atoms of the same element to have different chemical properties?
Yes. In the case of isotopes of water. An H2O ice cube is shown to float in a beaker of liquid water, while an ice cube of D2O (heavy water) is shown to sink in liquid water.
What is the isotopes in nobeluim?
The answer for isotopes is 259
Are most of the periodic table isotopes?
No most of them are not isotopes. Few elements exist as isotopes.
