Number of atomic masses radium has?
See the link below for the masses of all radium isotopes.
What element are atomic masses of all element based on?
carbon
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.
What is the sum of the atomic masses in a molecule?
The sum of the atomic masses in a molecule is called the molecular weight or molecular mass. It is calculated by adding the atomic masses of all the atoms in the molecule. This value is usually expressed in atomic mass units (amu) or grams per mole (g/mol).
What is atomic mass an average of?
"Atomic Mass" is not an average, it is tje total mass of all the electrons, protons and neutrons in an atom of an element. AVERAGE Atomic Mass is the AVERAGE of the Atomic Masses of all of the Isotopes of an element according to their natural proportions.
Do all elements have different atomic masses?
yes
Why are most atomic masses a decimal?
The atomic mass of an isotope of an element is the mass of the nucleons (neutrons + protons) in an atom of that isotope. This is nearly, though not exactly, equal to the number of nucleons, and so is nearly a whole number.The main cause for the atomic mass being fractional is that most elements have numerous isotopes, each with a different number of neutrons and so a different atomic mass. The atomic mass for an element is the average of the atomic masses of all its isotopes, weighted together in the proportion of the isotopes' abundance on earth. It is this weighting together that results in the numbers being fractional.
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.

What is strontium's atomic number written as a positive integer?
All atomic numbers are positive integers. Strontium's atomic number is 38.
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).

What has an average of the masses of all naturally ocuring isotopes of an element?
The atomic mass or atomic weight as it is sometimes called.
What is the sum of the atomic masses in a molecule?
The sum of the atomic masses in a molecule is called the molecular weight or molecular mass. It is calculated by adding the atomic masses of all the atoms in the molecule. This value is usually expressed in atomic mass units (amu) or grams per mole (g/mol).
