What is the atomic number and atomic mass of this element?
Atomic number is the number of protons. Atomic mass is (mostly) the sum of the masses of the protons and neutrons (more or less).
Number of atomic masses radium has?
See the link below for the masses of all radium isotopes.
Who find that atoms with same atomic number but different atomic mass?
Isotopes are atoms with the same number of protons (atomic number) but different numbers of neutrons, resulting in different atomic masses. These isotopes have similar chemical properties but may have different physical properties due to their different masses.
Why the atomic mass numbers listed for elements on the Periodic Table are not whole numbers.?
Why are atomic masses of elements not generally whole numbers? The atomic masses listed on the periodic table are a weighted AVERAGE of an element'sisotopes. ... An element's atomic number is the number of protons in its nucleus. Number of protons specifies atom type.
What are the atomic number and mass of the animals?
Animals are not atoms and have neither an atomic number nor an atomic mass.
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.
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.
Atoms having the same atomic number but different atomic masses?
Isotopes

Number of atomic masses does radium have?
See the link below for the masses of all radium isotopes.
Number of atomic masses radium has?
See the link below for the masses of all radium isotopes.
Is the mass and atomic mass the same?
No. The atomic weight is the number on the Periodic Table and is a weighted average of the atomic masses.

What is the mass number of copper?
AMU (Atomic Mass Unit) is the SI masses of particles for nucleus.
Is it okay to round atomic masses to the nearest whole number?
No, it is not okay to round atomic masses to the nearest whole number because atomic masses are typically reported to several decimal places to account for the average mass of isotopes present in nature. Rounding to the nearest whole number would lead to inaccurate calculations and results.
10 kinds of isotopes and their application?
Different atoms of the same element possessing different atomic masses but having same atomic number are known as Isotopes. Since the isotopic atoms have the same atomic number, they must contain an equal number of protons. As their atomic masses are different, there must be a difference in the number of neutrons they possess. They will show similar chemical properties but their physical properties will be different due to different masses.
