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.


Is the square root of a whole number always a whole number?

nope! take the square root of 5, 2.236067978... which is not a whole number! hope this helps!


What improper fraction is equal to 5 1.2?

It is 21/4... You take the whole number, multiply it by the Denominator and add the top number which is the Numerator... and use the current denominator and use it as the improper fractions denominator...


Why do you round mass numbers to the nearest whole number?

That is done mainly for basic chemistry. The normal practice is to take the weighted average of the various isotopes which, in almost all cases leads to numbers which are not whole.


How long would it take to write out each whole number from 0 to 1000000 on paper?

Assuming you could average one per second without a break, it would take about twelve days.


How do you convert a whole number into a mixed number?

Take the whole number and place it over one, for example: 34 could be 34/1


What is 105.27 rounded off to the nearest whole number?

Short answer: 105 Explanation: A whole number is one without a decimal. When you're rounding, take a look at the decimal. if the decimal is less than .50, then you round down to the current whole number, in this case 105. If the decimal is .50 or above, you round up to the next number, in this case, 106. Since the decimal is .27 we round down to 105.


What is the whole number of 76.3?

The whole number of 76.3 is 76. Whole numbers are the non-negative integers, and when converting a decimal to a whole number, you typically take the integer part, which is the number before the decimal point. Therefore, 76.3 rounded down to the nearest whole number is 76.


Do all isotopes have whole number atomic masses?

The short answer is yes. The long answer is that isotopes have different numbers of neutrons than other isotopes of the same element, so when expressing the mass of an isotope, you don't take an average; you just add the number of neutrons and the number of protons. However, that number is not entirely accurate since the mass of a proton and a neutron are very slightly different. So, if you want to be very exact, then no, the mass of an isotope is not a whole number, but it is very, very close.


What is a whole number denominator?

If you have the number 13 the denoninator would be 1. So like 13 over 1


What does not results in a whole number when you take the square root?

Any number that is not a perfect square.


What does round up numbers mean?

It simply means to take the number and then take it to the closest whole number, (may be a fraction)
