do you mean the why is the average Atomic Mass not a whole number? because if that is your question, then the answer is that each element has multipal isotopes and the mass you see on the Periodic Table is the average of all the isotopes together. So there has to be a decimal on the periodic table of elements
What else can I help you with?
The atomic mass of the elements are not whole value numbers because of the existence of?
D. Protons
Why the atomic mass numbers listed for elements on the Periodic Table are not whole numbers.?
Why are atomic masses of elements not generally whole numbers? The atomic masses listed on the periodic table are a weighted AVERAGE of an element'sisotopes. ... An element's atomic number is the number of protons in its nucleus. Number of protons specifies atom type.
Why are atomic numbers listed as whole numbers?
The atomic number is derived from how many protons are present in the nucleus of an atom. Becaue you cannot have a fraction of a proton present in an atom, atomic numbers must be non negative integers.
Choose the empirical formula?
To determine the empirical formula of a compound, you need the molar masses of its elements and their ratio in the compound. Calculate the ratio of the elements in terms of whole numbers, which will give you the empirical formula.
How are the actinide series elements created?
Elements with atomic numbers 89-94: natural elements.Elements with atomic numbers 95-98: artificial elements but they are also discoverd in nature as ultratraces.Elements with atomic numbers 99-103: artificial elements.
Why aren't atomic masses of elements not whole numbers?
because of its no. in table of elements
Why the mass numbers on the periodic table of elements are rarely whole numbers?
Elements also possess isotopes. So their average atomic mass is rarely whole number.
Why don27t elements in the periodic table have whole numbers for their atomic masses?
Because the masses of protons, neutrons and electrons are not whole numbers.
What are the whole numbers of 30?
I dont know does that help u
Why aren't the atomic masses of most elements whole numbers?
The atomic masses of most elements are not whole numbers because they take into account the average mass of all the isotopes of that element, which have different masses due to varying numbers of neutrons. This results in a weighted average that is not a whole number.
Do integers contain whole numbers true or false?
dont know
How many elements are in the set whole numbers between 3 and 15?
12
Why are all whole numbers not integers?
Whole numbers are 0 , 1 , 2 , 3 etc.. (dont contain negative) Integers are -2 , -1 , 0 , 1 , 2 , 3, ie they CONTAIN whole numbers
The atomic mass of the elements are not whole value numbers because of the existence of?
D. Protons
How do you change a whole number to a decimal?
You can't change a whole number to a decimal. A decimal and a whole number are both numbers. A decimal is just a number lower than a whole number, or a number in between two whole numbers.
Why are the elements 94 through 110 in the periodic table whole numbers?
1. All the atomic numbers are whole numbers. 2. If you think to atomic weight of heavy radioactive elements (atomic numbers from 93 to 118) is a rule of IUPAC to indicate in square parenthesis, [], the atomic mass of the most stable or known isotope.
Do you need to add whole numbers when subtracting fractions?
add? dont you mean subtract?
