Which isotopes of uncharged elements have different numbers?
The isotopes of the same element has the same atomic number. But the mass number (atomic mass) is different.
Is oxygen 16 and nitrogen 16 isotopes of each other?
No, they are isotopes with the same atomic mass. But they are isotopes of different elements and so are very different from on another. For example nitrogen-16 and nitrogen-14 are isotopes of the same element.
What subatomic particles can differ between neutral atoms of the same element?
The subatomic particle that makes atoms of different elements different from each other is the proton. This is given as the atomic number of the element on the periodic table.
What is the difference in the modern periodic table and Mendeleev's table?
The periodic table is now complete and can be displayed using the integral atomic numbers. In Mendeleev's time there were still unknown elements. In fact, one of the primary uses of his table was to predict the properties of elements that had not yet been isolated. (His 1869 table included speculative names for some expected elements.) -- In Mendeleev's periodic table, transition elements were placed in another group. --In Mendeleev's periodic table, noble gases were written on left side. In the modern periodic table, noble gases are written on right side.
Why are atomic masses of elements usually not whole numbers?
The atomic mass listed in the periodic is found by taking the average of all the different isotopes of a given element found in nature, weighted for their natural abundance.Note that the atomic mass is not the same as the atomic weight. The atomic mass is the weight of one specific isotope of one atom, and is expressed in "atomic mass units" or amu. The atomic weight is expressed in grams per mole (g/mol) and is the weighted average of all the isotopes weighted by their abundance.See the Web Links for more information about atomic mass and atomic weight.
Mass number Why is it not the number on the periodic table?
Elements have different isotopes and each isotope will have different atomic mass. As such it is not possible to list the mass number of all the isotopes on the periodic table. However, the atomic mass is generally given on the periodic table which is generally calculated taking into account all the isotopes and its percentage.
How does the isotopes chlorine-35 and 37 occupy the same place in the periodic table?
Isotopes of Chlorine-35 and 37 have different atomic wt. but same atomic number. And in the modern periodic table, the elements are arranged in order of their atomic number AND NOT atomic wt. hence, Chlorine-35 and 37 occupy same place in the periodic table.
What makes isotopes different from elements on the periodic table?
isotopes of a given element have the same atomic number (or number of protons) but vary in the number of neutrons and hence the mass 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 the periodic table gives the mass number of the most common isotopes of an element?
The periodic table give the atomic numbers and the atomic weights of chemical elements.
What is the position of isotopes in the modern periodic table?
Isotopes are atoms of same element having different atomic mass, but the same atomic number. Isotopes have not been given separate place in the modern periodic table.
What is an element's atomic mass not listed as a whole number on the periodic table?
Few elements have isotopes. their atomic mass is not a whole number.
How scovery of isotopes explain why atomic wieghts do not always give the correct order of elements?
This is due to the fact that all elements have isotopes, meaning that there atomic weight is in fact much greater than stated in the periodic table. This means that the elements are only weighed by their compound and not including the isotopes.
What isotopes of uncharded elements have different numbers?
The atomic number of the isotopes of an element is identical; the mass number is different.
Why isotopes have same position in periodic table?
Isotopes have the same position in the periodic table because they have the same number of protons, which determines the element they belong to. However, they differ in the number of neutrons, which results in different atomic masses.
Why the mass number of the same atom of an element is not constant?
Since you have isotopes of elements. Isotopes are elements with different number of neutrons hence why the different atomic masses for the same elements.
An average of the masses of all the naturallly occurring isotopes of an element?
The weighted average for all isotopes that occur in nature for an element is its atomic weight listed on the Periodic Table of the elements.
