How is the atomic mass of an element determined?
The atomic mass of an element is determined by calculating the weighted average of the masses of its isotopes, taking into account their relative abundance.
How can one determine the atomic weight of an element?
The atomic weight of an element can be determined by calculating the weighted average of the masses of its isotopes, taking into account their abundance in nature. This information is typically found on the periodic table of elements.
What is Lother Meyer's curve?
a curve plotted by Lother Meyer between atomic mass and atomic volume of different elements is called Lother Meyer's curve. In this curve similar elements were found to occupy similar positions. Lother Meyer concluded the results obtained from the curve as, "atomic volume of elements are periodic functions of their atomic masses". But later on it was modified as atomic volumes of elements, are periodic function of their atomic numbers.
How do you calculate the atomic weight of an element?
The atomic weight of an element is calculated by taking the weighted average of the masses of its isotopes, based on their abundance in nature. This is done by multiplying the mass of each isotope by its abundance, adding these values together, and then dividing by 100.
Why are chocolate eggs associated with Easter?
No one really knows. i think it is to keep all the kids happy during Easter Masses.
By adding the atomic masses?
You will get the atomic bomb!
The current standard for atomic masses is?
The current standard for atomic masses is based on the Carbon-12 isotope. It is defined as exactly 12 atomic mass units (amu), with all other atomic masses determined relative to it. This standard allows for consistency in measurements and comparisons of atomic masses across different elements.
How were the atomic number and the atomic masses of the elements determined?
Atomic masses are determined by mass spectrometry. The atomic number is identic with the number of protons in the atom - depends on position in the periodic table.
The average atomic mass of an element is the average of the atomic masses of its?
The average atomic mass of an element is the average of the atomic masses of its isotopes (that is a weighted average). You have to take into account the abundance of each isotope when they do your averaging.
What elements have such small masses that they are not even considered when atomic masses are calculated?
Electrons
What atoms with same atomic number but different atomic masses?
Isotopes are atoms with the same number of protons (same atomic number) but different numbers of neutrons, leading to different atomic masses. For example, carbon-12 and carbon-14 are isotopes of carbon with atomic number 6 but atomic masses of 12 and 14 respectively.
Which statement best explains why most atomic masses on the periodric table are decimal numbers?
Most atomic masses on the periodic table are decimal numbers because they are weighted averages of the masses of all isotopes of an element, taking into account their relative abundance. Since isotopes have different masses, the atomic mass is typically not a whole number.
Which Russian scientist related chemical properties and atomic masses?
Dmitri mendeleev related the chemical properties and atomic masses around 1860
What did Dimitri Mendeleeve do?
Dmitri arranged the elements in order of increasing atomic masses. He arranged elements in rows and columns according to atomic masses.
State the name and the mass of the isotope relative to which all atomic masses are measured?
The isotope used as the reference for atomic masses is carbon-12, with a mass of 12 atomic mass units (amu).
Atoms having the same atomic number but different atomic masses?
Isotopes
Why interval notation cannot be used to represent the set of atomic masses given?
Why interval, notation cannot be used to represent instead of atomic masses
