Is promethium a natural or man made?
Although promethium exist in traces in the Earth crust it is an artificial element.
How many protons and neutrons are in promethium?
Promethium has 61 protons and electrons.For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope - 61
How many protons neutrons and electrons are in promethium?
Promethium has 61 protons and electrons; For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope - 61
What element has 47 neutrons and a mass number of 108?
To determine the element with 47 neutrons and a mass number of 108, you can subtract the number of neutrons from the mass number. This gives you 108 - 47 = 61 protons. The element with 61 protons is promethium (Pm).
How many valence electrons does promethium have?
Promethium has nine isotopes, their numbers ranging from 143 to 151. None of the isotopes are naturally occurring, yet some stars have minute amounts of promethium.
Is promethium a flamable element?
Promethium is not flammable.
How common is promethium?
Promethium is a rare artificial element.
How is promethium abundunt?

Is promethium a mineral?
Promethium is a chemical element, a metal.
Who is promethium?
Promethium is a chemical element, atomic number 61.
What is the atomic number 61?
That's impossible. The atomic mass is the number of protons plus the number of neutrons.If you meant the element with atomic number 61, the name is Promethium. But it doesn't have 108 neutrons.
