What is the energy level of rubidium?
So, according to the question, rubidium Rb has an atomic number of 37. Then, based on the atomic number of Rb i.e. 37 we will write the electron configuration: 1s22s22p63s23p64s23d104p65s1. By referring to the electronic configuration of Rb the outermost electron lies in 5th energy level.
How do you find the atomic weight of copper?
63.546 u
Copper/Atomic mass
– Among these two isotopes of copper, 63Cu occurs as 69.2% of abundance and that of 65Cu occurs as 30.8% abundance. – The masses of these two isotopes as per the given data are, 63Cu=62.93 amu and 65Cu= 64.93 amu. Thus, the average atomic mass of the given isotopes is 63.546 amu.
What creates xenon-129?
Naturally occurring xenon (54Xe) consists of seven stable isotopes and two very long-lived isotopes. Xe is produced by beta decay of 129I (half-life: 16 million years); 131mXe, 133Xe, 133mXe, and 135Xe are some of the fission products of both 235U and 239Pu, so are used as indicators of nuclear explosions.
What is xenon-129 used for?
Xenon-129 isotope is used for nuclear magnetic resonance (NMR) spectroscopy studies; Xenon-129 isotope is used for mass spectrometric analysis in planetary studies; Xenon-129 isotope is used for as contrast agent in magnetic resonance imaging (MRI);
How much does 1 mole of iron weigh?
55.847 grams
Thus, since the atomic mass of iron is 55.847 amu, one mole of iron atoms would weigh 55.847 grams.
What is the atomic mass of xenon?
The atomic mass of the element Xenon is approximately 131.293 atomic mass unit
What does the atomic weight tell you?
Atomic mass of an element tells us the number of times an atom of the element is heavier than of the mass of an atom of carbon-12. A unit suitable for the mass of atoms and the mass of subatomic particles is the atomic mass unit (u).
What determines the atomic weight or mass of an atom?
Atomic mass, which is also known as atomic weight, is the average mass of atoms of an element, calculated using the relative abundance of isotopes in a naturally occurring element . Atomic mass indicates the size of an atom.
Is atomic weight identical to the atomic mass?
Atomic weight is identical to atomic mass. The number of neutrons always equals the number of protons. The number of neutrons always equals the number of electrons.
