Elements are represented by what?
Their symbol, atomic weight, and atomic number.
Why don't the elements on the periodic table have a whole number as their atomic weight?
Elements exist as isotopes in nature. So their atomic weight is not a whole number.
Why do some elements not have relative atomic masses eg. radium?
All the elements has an atomic weight; sometimes for the unstable radioactive elements is indicated only the value of the atomic mass of the most stable isotope.The term atomic weight is used for elements and the term atomic mass for isotopes (after the rules and the tradition of IUPAC).
Why atomic weight of chlorine is 35.5 though isotopes of chlorine 35 and 37?
The atomic weight for each element on the periodic table represents a weighted average of the masses of all naturally occurring isotopes of an element. Because of this, the elements do not have whole-number atomic weights. An exception is the atomic weight for some elements written inside parentheses. These elements do not have stable isotopes and the atomic weight listed is the atomic weight for the longest lived isotope.
How you calculate the relative atomic weight of uranium?
The atomic weight of an element is derived from the atomic masses of the isotopes of this element and from the percentage of these isotopes. The correct terms are: - atomic weight for elements - atomic mass for an isotope
Which element has an atomic weight?
All elements have an (atomic) weight or mass.

What does an elements locatio in the periodic table tell you about that elements?
Atomic weight
Does uranium have the greatest atomic weight?
Uranium has the greatest atomic weight (238,02891 a) between the natural elements.
Why do some elements not have relative atomic masses eg. radium?
All the elements has an atomic weight; sometimes for the unstable radioactive elements is indicated only the value of the atomic mass of the most stable isotope.The term atomic weight is used for elements and the term atomic mass for isotopes (after the rules and the tradition of IUPAC).
What elements on the periodic table are usually identified with three things?
Symbol, atomic number, and atomic weight.
Why atomic weight of chlorine is 35.5 though isotopes of chlorine 35 and 37?
The atomic weight for each element on the periodic table represents a weighted average of the masses of all naturally occurring isotopes of an element. Because of this, the elements do not have whole-number atomic weights. An exception is the atomic weight for some elements written inside parentheses. These elements do not have stable isotopes and the atomic weight listed is the atomic weight for the longest lived isotope.
Which element has no atomic weight?
all elements have an atomic weight, because all of them have electrons and protons, and every electron and proton have a weight.
How you calculate the relative atomic weight of uranium?
The atomic weight of an element is derived from the atomic masses of the isotopes of this element and from the percentage of these isotopes. The correct terms are: - atomic weight for elements - atomic mass for an isotope
What are four things on the periodic table that tells you about the elements atoms?
the atomic number, the atomic weight, the atomic symbol and atomic name.
Is there a difference between mass and atomic mass when dealing with elements?
Generally the term "atomic mass" is used for isotopes. For elements is preferred now "atomic weight".
