What else can I help you with?
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.
Can you find any cases in the first 90 elements in which consecutive elements do not have increasing atomic weights?
Yes, in the first 90 elements of the periodic table, there are cases where consecutive elements do not have increasing atomic weights. For example, between lithium (Li) with an atomic weight of 6.94 and beryllium (Be) with an atomic weight of 9.01, the atomic weight decreases instead of increasing.
What is the atomic weight of the element potassium?
The atomic number of potassium is 19 and the atomic weight is 39.0983 grams per mole. See the Web Links to the left for a periodic table where you can find the atomic number and atomic weight of all the elements!
What is the unit of weight for elements?
The unit of weight for elements is typically measured in atomic mass units (amu) or grams. The atomic mass unit is defined as one twelfth of the mass of a carbon-12 atom.
Which element has an atomic weight?
All elements have an (atomic) weight or mass.
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.
Does uranium have the greatest atomic weight?
Uranium has the greatest atomic weight (238,02891 a) between the natural elements.
What does an elements locatio in the periodic table tell you about that elements?
Atomic weight
Can you find any cases in the first 90 elements in which consecutive elements do not have increasing atomic weights?
Yes, in the first 90 elements of the periodic table, there are cases where consecutive elements do not have increasing atomic weights. For example, between lithium (Li) with an atomic weight of 6.94 and beryllium (Be) with an atomic weight of 9.01, the atomic weight decreases instead of increasing.
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.
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".
How are the elements in a period different?
By their atomic weight..protons and electrons.
What is the atomic weight of the element potassium?
The atomic number of potassium is 19 and the atomic weight is 39.0983 grams per mole. See the Web Links to the left for a periodic table where you can find the atomic number and atomic weight of all the elements!
The atomic weight unit was a system devised to make what?
The correct expression - after IUPAC rules - is atomic weight.The atomic weight unit is necessary to appreciate the atomic weights of chemical elements.
