Weighted average atomic mass?
What is weighted average atomic number
What is weighted average mass of an element isotopes?
average atomis mass
Is an average mass of the different isotopes of the element?
Yes, weighted by how often the isotopes are found in nature.
Weighted average mass of the mixture of its isotopes?
Average atomic mass I think.
Why is a weighted average required for calculating atomic mass?
Isotopes - that same element with a different atomic weight.
What does a mass number determine?
mass number = number of protons + number of neutrons DIFFERENT FROM ATOMIC MASS atomic mass = weighted average of all the isotopes of that element
Why do elements which exists as isotopes have fractional atomic mass?
Each isotope of an element has a different Atomic Mass, so an average is taken of all the isotopes, but the average is weighted because the natural abundance (%) of each isotope is factored in. If hydrogen-1 is much more abundant than deuterium and tritium, then the weighted average will be closer to 1 than 2 or 3 but not a whole number. The following equation shows how percent abundance factors into the weighted average. (atomic mass A)(X% abundance) + (atomic mass B)(Y% abundance)...=(weighted average of all isotopes of the element)(100% abundance)
Why do objects have different mass?
Objects have different mass because they not weighted the same..
What is the weighted average atomic mass of bromine?
79.9173125
The atomic mass of an element is defined as the weighted average mass of that element's?
For the chemical elements the correct expression is atomic weight.This value is the weighted average mass of the natural isotopes of this element.
How is the atomic mass of an element is affected by the distribution of its isotopes in nature?
Isotopes have a different amount of Neutrons. The atomic mass is the sum of Protons and Neutrons. Therefore having a different number of Neutrons makes the atomic mass greater. Or vice versa. Boom. Solved.
Why do scientist use weighted average instead of straight mathematical average of masses of isotopes to indicate the atomic mass of an element?
The percentage of each isotope is different.
