Which element in the actinide series has the greatest atomic number?
Lawrencium (Lr) with the atomic number 103.
What is the mass of one atom in protactinium?
The atomic weight of protactinium is 231,03588.
Protactinium with 91 protons and a mass of 234 undergoes alpha decay and becomes what with an atomic number of what and an atomic mass of what?
It would be actinium with 89 protons and a mass of 230.
How many protons in thorium-232?
Thorium has an atomic number of 90, or in other words, 90 protons in its nucleus. The mass number or the identification of the -232 isotope with its 142 neutrons is a red herring - in isotopy the number of neutrons may vary but the atomic number or the count of protons is the same. If the atomic number varied from 90 it would by definition no longer be thorium.
What group number does protactinium belong to?
Protactinium is a member of the actinoids series.
Which element in the actinide series has the greatest atomic number?
Lawrencium (Lr) with the atomic number 103.
What is the atomic radius of protactinium?
The atomic radius of protactinium is 180 pm.

Protactinium has 91 electrons; the valence is 4 or 5.
When thorium emits beta particle the resulting nucleus has a atomic number?
The resulting element is protactinium, atomic number 91.
What is the atomic weight of protactinium?
ProtactimAtomic Number: 91Atomic Weigt: 231.0Symbol: Pa
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 the name of the element with the atomic numer91?
The element with atomic number of 91 is protactinium, Pa. It is an inner transition metal.
