How does the presence of isotopes effect the weight of elements on the periodic table?

The Periodic Table gives you the actual weight of an element, so that if you had a sample in your laboratory and weighed it, your result would agree with (or be very close to) what the periodic table indicates. The weight of an element depends upon the relative abundance of the various isotopes of which it is composed. Each isotope has a different weight, so the weight of the element is influenced by each isotope, with the more abundant isotopes having a correspondingly greater influence.

Contribution of Johann Dobereiner for the periodic table?
An organized tabular arrangement of chemical elements on the basis of their electron configurations, atomic number and recurring chemical properties is the periodic table of elements. Johann Wolfgang Dobereiner has a great contribution in periodic table of elements because he foreshadowed the periodic law for the chemical elements.
Do isotopes with the same elements have the same physical properties?
The physical properties are of course different. The chemical properties are considered identical but this is not a general rule; for example hydrogen isotopes (1H and 2H) have some different chemical and biochemical properties.
What do isotopes matter?
The mass effect between deuterium and the relatively light protium affects the behavior of their respective chemical bonds, by means of changing the center of gravity (reduced mass) of the atomic systems. However, for heavier elements, which have more neutrons than lighter elements, the ratio of the nuclear mass to the collective electronic mass is far greater, and the relative mass difference between isotopes is much less. - See more at: http://www.chacha.com/question/what-cases-are-differences-between-isotopes-important#sthash.oOOVoNRU.dpuf
How does the periodic table effect the modern world?
because if you find out what a periodic table is and go on a different website you can find it out but everyone wanted to see what is was so if you need more information go on a different website.
Ions are charged and isotopes are not true or false?
True. Isotopes are defined by the amount of neutral neutrons which have no effect on the polarity of the atom. ions are defined by a differing amount of protons and electrons, therefore charging them.
How does the periodic table help scientists?
well all the chemists from all around the world can know communicate and understand each other without having to learn what the element is in 90+ languages and now they know the mass of each element because that is how it is put in order the mass is the little number next to the symbol
Which is not an effect of chemical reactions in the cells of living organisms?
Isotopes are forming and canging...
As elements of group 1 of the periodic table are considered in order from top to bottom ionization of a element decreases this decrease is do to?
Increasing radius and increasing shield effect.
Will radioactive isotopes cause a dark stool?
One does not usually ingest radioactive isotopes, however if one did I expect the initial effect (if you were not poisoned by the elements concerned) would be to for the radiation (alpha or beta) damage the tissues in contact with the isotopes. This would cause them to bleed and the blood would indeed cause the stool to be dark. However, that would be just the start of your problems.
Why doesn't water appear on the periodic table?
Water is not on the periodic table of elements because elements cannot be broken down into different substences and water can; it is two part Hydrogen one part Oxegen, thus you get H2O or water.

Why do we need atoms?
According to modern Periodic Table Atomic numbers are the fundamentals in order to explain the properties of an atom.One thing more and that is the concept of isotopes also make the atomic masses less strong to explain atomic properties which has no effect on atomic numbers.

What does the term relative unity mean in design?
Elements have an effect of their own and are not subordinate to the total effect.

What element has no physical and chemical isotopes known?
The words are English ones and the grammar is mostly correct, but put together in that way the result is nonsense.Firstly, "physical and chemical isotopes" is meaningless. Isotopes have different physical properties, and may even behave different chemically due to the kinetic isotope effect, but I've never heard anyone refer to a "chemical isotope" or "physical isotope".For an element to officially be considered "discovered", someone has to have produced an isotope of it and that experiment has to be repeatable. So all known elements have at least one isotope, which is at least one more than "no isotopes".Some of the higher-mass elements may as yet only have had a single isotope produced, if what you were trying to get at was "no other isotopes". However, this doesn't mean no other isotopes are possible, it just means we haven't made them yet. There's good reason to believe that, in the case of the high-Z actinides, the isotopes we haven't been able to make yet may be more stable than those we have been able to make, because the ones we can make tend to be on the neutron-deficient side and more neutrons would probably have a stablizing effect.
