What is the atomic weight of tungsten?
183.84 uTungsten / Atomic mass
What is the atomic weight of potassium?
39.0983 uPotassium / Atomic mass
Why is the atomic mass of potassium 39?
Explanation: Protons (the atomic number) and neutrons both contribute to the atomic mass. If you therefore subtract the number of protons (19) from the atomic mass (39), you are left with the number of neutrons (=20).

Why is tungsten so heavy?
The density of different elements is a reflection of the size of their component atoms. The lower you get on the periodic table, the larger and heavier the atoms. “The heavier elements, like tungsten, have more protons and neutrons in the nucleus and more electrons in orbit around the nucleus,” says Newsam.
How is atomic weight calculated?
The atomic weight of any atom can be found by multiplying the abundance of an isotope of an element by the atomic mass of the element and then adding the results together. This equation can be used with elements with two or more isotopes: Carbon-12: 0.9889 x 12.0000 = 11.8668. Carbon-13: 0.0111 x 13.0034 = 0.1443.
Is atomic mass and atomic weight same?
Atomic weight, also called relative atomic mass, is the ratio of the total weight of the atoms of a chemical substance to a norm. The normal unit of atomic mass has been one-twelfth of the atomic mass of the carbon-12 isotope since 1961.
Is the atomic mass of potassium-39 or 40?
The atomic mass of potassium is 39 u . >>The atomic mass of potassium is 39 u .
How are potassium-39 Potassium 40 and potassium 41 different from each other?
They are different in their masses or mass number. Potassium- 39 has an atomic mass of 39 amu or mass number is 39, Potassium- 40 has an atomic mass of 40 amuor mass number is 40, and Potassium- 41 has an atomic mass of 41 amuor mass number is 41. The three isotopes have different numbers of neutrons.
Why is Kalium called potassium?
The name is derived from the english word potash. The chemical symbol K comes from kalium, the Mediaeval Latin for potash, which may have derived from the arabic word qali, meaning alkali. Potassium is a soft, silvery-white metal, member of the alkali group of the periodic chart.
Why does potassium 40 have a different mass number for potassium 39?
Potassium- 39 has 1 neutron less than Potassium- 40 and two neutrons less than Potassium- 41.
