Why is the krypton atomic mass not determined?
The relative atomic mass is 83.798. So where did you get that it is not determined.
How do you get the atomic mass and and atomic number?
it is simple. all you need to do is look in the periodic table the numbers above and under the letter.Atomic number is determined from the number of protons in the nucleus. Atomic mass is determined from the number of protons AND neutrons in the nucleus. Since elements have multiple isotopes with differing numbers of neutrons, the atomic mass reported on periodic charts is usually the average atomic mass. As the first person who answered this question pointed out, you can usually find the atomic number by looking for a number above the atomic symbol for the element in the the table (H for hydrogen, C for carbon, Fe for Iron, Au for gold, etc.). Sometimes the number will be below the symbol but in bold font. When the periodic table gives an atomic mass, it is usually given under the atomic symbol and is almost always some kind of decimal number that is always greater than the atomic number, for example: Carbon has an atomic number of 6and an atomic mass of 12.0107 amu.
What is the atomic mass-?
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
The equation of atomic mass?
== The equation of atomic mass is protons+nuetrons== atomic mass. ===
What is the atomic mass of colbat?
Cobalt is an atomic mass of 58.93 atomic mass units
Why is the krypton atomic mass not determined?
The relative atomic mass is 83.798. So where did you get that it is not determined.
How are atomic mass on the periodic table calculated?
Atomic mass is determined by mass spectrometry.
What two pieces of information can be determined from the atomic mass?
The number of protons and neutrons in the atom can be determined from the atomic mass. The atomic mass represents the average mass of the isotopes of that element in atomic mass units.
How you determined the relative atomic mass of oxygen?
The relative atomic mass of oxygen is determined by taking the weighted average of the isotopic masses of its naturally occurring isotopes (O-16, O-17, O-18) in respect to their abundance in nature. This calculation gives an average value close to 16, which is the standard atomic mass unit for oxygen.
How are electrons determined?
By subtracting the atomic mass and atomic number
Atomic mass is determined by the number of protons plus the number of?
neutrons in an atom's nucleus. It is measured in atomic mass units (amu) and provides the total mass of an atom. The atomic mass is approximately equal to the sum of the protons and neutrons in the nucleus, as the mass of electrons is negligible.
Is the atomic mass determined by oxygen-16?
The unit for atomic mass is 1/12 from the mass of the isotope 12C.
How can an atom's protons be determined?
By the atomic mass
How was the atomic mass determined for sodium?
The atomic weight (not mass) of sodium is 22,989 769 28(2).
Atomic mass of an atom is determined by the combined masses of?
Atomic mass of an atom is determined by the combined masses of its protons, neutrons, and electrons. Protons and neutrons contribute most of the mass, as they are much heavier than electrons. The atomic mass is usually given in atomic mass units, where 1 unit is defined as 1/12 the mass of a carbon-12 atom.
How do you calculate isotopic masses?
The atomic mass of isotopes is determined by mass spectrometry.
How is molar mass of an element determined?
the Atomic Mass in g/ml is the molar mass of the element
