Explanation:
This element is Rhodium because it has an atomic number of 45 on the periodic table.
How did we come about this?
- The number of electrons for every atom is unique whenever in their neutral state.
- We can deduce the number of electrons from the respective orbitals.
- Each orbitals and energy levels have respective number of electrons they can accommodate.
- From the electronic configuration given:
The number part: coefficient is the energy level i.e 1,2,3,4,5
power is the number of electrons
The letter is the orbitals the electrons are filling: s, p ,d and f
If we sum all the powers, we arrive at 45.
This is 45 electrons.
The atomic number is the same as the number of electrons and number of protons for every neutral atom.
Rhodium occupies the 45th position on the periodic table.
Part 2:
The electronic configuration of silver can be written as:
Expected configuration: [Ar] 4d⁹ 5s²
Observed configuration: [Ar] 4d¹⁰ 5s¹
Now, as a result of special stability of filled and half-filled sublevels, the expected electron configuration based on the Aufbau principle may be different in some atoms.
In silver, the 5s orbital becomes partially filled and 4d fully filled and both becomes stable.
The expected configuration does not bring any stability of any sort for the atom.
