Which best describes the definition for the atomic mass of the element?
it is the weighted average of the masses of an element's isotopes.
Which is the average of the mass numbers of an element's isotopes?
the Atomic Mass
In each element square on the periodic table there is a number that has a decimal point in it what does this number represent?
The number with a decimal point in each element square on the periodic table represents the average atomic mass of that element. It takes into account the mass of different isotopes of the element and their relative abundance in nature.
Isotopes are atoms of the same element that different numbers of?
Isotopes are atoms of the same element that have different numbers of neutrons in their nuclei. This leads to variations in atomic mass for isotopes of the same element.
Which two notations represent atoms that are isotopes of the same element?
The two notations represent atoms that are isotopes of the same element is 121 Sn and 119 Sn. The atomic mass of an element is defined as the weighted average mass of that elements naturally occurring isotopes.
Why are the atomic mass numbers of an element not hole numbers?
Its the average of the weight of the different isotopes of that element.
What is the average mass of the isotope of an element?
the average mass numbers of the isotopes of an 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 is there an average atomic mass?
There is an average atomic mass because all atoms of the same element do not have the same amount of neutrons (isotopes), therefore variations in atomic mass exist. The average atomic mass of an element is the estimated average of all the atoms of the same element, given the average of different isotopes in a scientific sample.
How does the average atomic mass of an element differ from the mass of an individual atom of the same element?
The average atomic mass takes into account the different isotopes of an element and their relative abundance, while the mass of an individual atom is specific to that particular isotope. The average atomic mass is a weighted average based on all isotopes present in a sample, providing a more accurate representation of the element's mass in nature.
What is weighted average mass of an element isotopes?
average atomis mass
What Have different isotopes of the same element?
Isotopes of the same element have different numbers of neutrons and mass.
Which best describes the definition for the atomic mass of the element?
it is the weighted average of the masses of an element's isotopes.
What does isotopes have to do with mass numbers?
isotopes of the same element have different mass number
What is the average of the mass numbers of isotopes of an element?
the atomic mass
What is it called when you have the same element but different mass number?
They are isotopes of that element, they have different neutron numbers.
What is the definition for atomic mass?
so the mass of an atom is determined by the number of protons and neutrons in an element. For a given element, the number of protons is the same but the number of neutrons can vary (an element can have various isotopes). Therefore, the average atomic mass of an element is simply a weighted average of the masses of all the isotopes of that element. (a weighted average means that how common an isotope is is taken into account when incorporating it into the average, so rare isotopes will not count as much as common isotopes)
