What is the atomic number of protactinium?
Protactinium, with the chemical symbol Pa, is the chemical element with the atomic number 91.
When uranium 238 changes into protactinium 234 how many protons does it lose?
Uranium-234 become protactinium by emission of a beta particle. A proton is transformed in a neutron.
What do you get when you take one proton from uranium 234?
An atom with 91 protons is an isotope of protactinium.
What happens if an atom of uranium loses a proton?
If an atom of uranium loses a proton, it becomes an atom of an element with one less proton in its nucleus, known as an isotope of a different element. This change can alter the atomic number, mass number, and chemical properties of the atom.
What group number is protactinium in?
Protactinium is a member of the actinoids family.
What group number does protactinium belong to?
Protactinium is a member of the actinoids series.
Chemical symbol for protactinium?
The chemical symbol of protactinium is Pa.
How many neutron and protons are in protactinium?
Protactinium has 91 electrons; the valence is 4 or 5.
Is protactinium a metal?
Because the properties (chemical and physical) of protactinium are the general properties of metals.
How many electrons and protons does protactinium have?
Protactinium has 91 protons and electrons; the number of neutrons is different for each isotope: Number of neutrons = Atomic Mass of the isotope - 91
What is beta decay of thorium 234?
In beta decay of thorium-234, a neutron in the nucleus of thorium-234 is transformed into a proton, releasing an electron (beta particle) and an antineutrino. This process converts the thorium-234 nucleus into protactinium-234.
How many protons will uranium have after releasing a beta particle?
It depends on whether the beta decay sequence is beta- or beta+. In beta-, the atom will gain a proton, changing into neptunium. In beta+, the atom will lose a proton, changing into protactinium.
