What elements have such small masses that they are not even considered when atomic masses are calculated?
Electrons
Which statement best explains why most atomic masses on the periodric table are decimal numbers?
Atomic masses are a weighted average of the naturally occurring isotopes.
Number of atomic masses radium has?
See the link below for the masses of all radium isotopes.
When masses combine to form elements with larger masses?
Atomic fusion occurs when masses combine to form elements with larger mass.
Is atomic masses measured in amus?
Yes it is true.
How do atomic numbers and atomic masses increase in the periodic table?
The atomic number and atomic masses increase as you move from left to right.
By adding the atomic masses?
You will get the atomic bomb!
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
How are the atomic numbers and the atomic masses of the elements related to how the elements are arranged on peridoic table?
Elements are arranged in a periodic table by atomic number, lower on top and left. Atomic masses have no direct relationship to the arrangement of atoms, although generally atoms with higher atomic numbers will have higher atomic masses. (There are at least three exceptions for atoms with atomic numbers differing by 1.)
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.
Atoms having the same atomic number but different atomic masses?
Isotopes
What atoms with same atomic number but different atomic masses?
Isotopes of the same element have the same number of protons (atomic number) but differ in number of neutrons (hence atomic masses).
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
Which statement best explains why most atomic masses on the periodric table are decimal numbers?
Atomic masses are a weighted average of the naturally occurring isotopes.
