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 is the atomic number of protactinium?
Protactinium, with the chemical symbol Pa, is the chemical element with the atomic number 91.
What is the mass of one atom in protactinium?
The atomic weight of protactinium is 231,03588.
Which element in the actinide series has the greatest atomic number?
Lawrencium (Lr) with the atomic number 103.
A sub atomic particle which determines the atomic number?
The atomic number of an element is equal to the number of protons in the nucleus of that element.
How many neutron and protons are in protactinium?
Protactinium has 91 electrons; the valence is 4 or 5.
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
Is an atomic number always equal to the number of protons?
Yes, it is. The type of atom is defined by the atomic number. Usually, when an atom undergoes a chemical reaction, only the sharing/possession of electrons changes, and the number of protons (and so the atomic number of the element) stays the same. When an atom somehow undergoes a nuclear reaction, which is possible, the number of protons sometimes do change, but in that case the atomic number (and thus the element type) becomes different as well.
What is the atomic radius of protactinium?
The atomic radius of protactinium is 180 pm.

What element has 61 protons?
The element Silver has 61 neutrons. Its symbol on the Periodic Table is 'Ag'.
Which element in the actinide series has the greatest atomic number?
Lawrencium (Lr) with the atomic number 103.
If atomic number of carbon changes from 6 to 7 does it remain carbon?
No, it becomes nitrogen. Remember, the atomic number is the number of protons, and protons determine the element.
What is the relative atomic mass of an protactinium?
Pottasium is a meta element. Atomic mass of it is 39.
