Isotopes are the varying molecular weights of the atom caused by the addition or removal of neutrons.

What are normal elements in the periodic table?

positive element is an example of a normal element!!


Is 2 protons 2 neutrons and 2 electrons normal?

It is normal for the isotope of the element helium. 2He4 isotope has 2 protons, 2 neutrons and 2 electrons.


What is an isotope how does it differ from the standard of an element?

First: isotopes are not 'special' forms of elements, they are just (normal) elements.Isotopes of one element are only different nuclear configurations of that same element, which varies only in the number of neutrons present: thus only their mass is different.Since mass is not a chemical property, isotopes are chemically speaking identical and that's why they are on the 'same spot' in the (chemical) Periodic Table: 'iso' = same, 'topos' = place.


What is the radioactive isotope in the periodic table?

A normal periodic table does not list isotopes, but elements, almost all of which occur in more than one isotope, and there is probably at least one radioactive isotope for every element. Instead of the periodic table, a table of nuclides is needed to answer this question.


How does an isotope differ from a normal atom?

When an atom is of the same atomic number, atomic mass, etc. to the one on the periodic table (Lets use Boron for example) Then B is the regular atom. But if you change the number of nuetrons (from 6-to-7 or whatever number) ; because the number of protons never changes; you will get a different atomic mass, so an isotope is the atom with a different atomic mass. You write an isotope atom with the elements symbol and to the left of it you script (In the top left corner really small like an exponent) the new atomic mass. So in this case B would now be 12B. (except scripted, but I sadfully forgot how to do that on a computer....)

How many isotope of magnesium differ from normal atom?

All the isotopes have a different number of neutrons in the nucleus.


What is an aton with a different mass number than normal?

An isotope of the element. The mass number is the number of protons and neutrons in the nucleus.

What element has 1 protons 1 neutrons and 2 electrons?

It is hydrogen element. It is tritium isotope of hydrogen.


How is nuclear change differ from normal chemical change?

Nuclear change usually (but not always) changes the element of an atom itself; at the very least, it changes the isotope of the atom, altering its radiological properties (such as its half life). A chemical change means a change to a molecule in which the atom is bound.

Frequency of specific elements always the same?

In a stable isotope, the frequency of specific elements remains consistent under normal conditions due to the presence of a constant number of protons, electrons, and neutrons within the atoms. This stability ensures that the relative abundance of isotopes of an element does not change without external influences.
