Who said that no two electrons can have the same set of?
Wolfgang Pauli formulated the law stating that no two electrons can have the same set of quantum numbers.
What is the statement that no two electrons in the same atom can have the same for quantum numbers?
The Pauli Exclusion Principle
The Pauli Exclusion Principle states that, in an atom or molecule, no two electrons can have the same four electronic quantum numbers. As an orbital can contain a maximum of only two electrons, the two electrons must have opposing spins.
Which scientist is responsible for the rule that states only two electrons are allowed in one orbital?
Pauli exclusion principle, assertion that no two electrons in an atom can be at the same time in the same state or configuration, proposed (1925) by the Austrian physicist Wolfgang Pauli to account for the observed patterns of light emission from atoms.
Who invented Paulis exclusion principle?
As this model developed, electrons were assigned certain quantum numbers corresponding to distinct states of energy and movement. In 1925, Wolfgang Pauli introduced two new numbers and formulated the Pauli principle, which proposed that no two electrons in an atom could have identical sets of quantum numbers.
Who was the person whose work led to a periodic table based on increasing atomic number?
Mendeleev
The person whose work led to a periodic table based on increasing atomic number was b) Mendeleev.
Which of the following states that no more than two electrons can occupy an atomic orbital?
Pauli’s Exclusion Principle states that no two electrons in the same atom can have identical values for all four of their quantum numbers. In other words, (1) no more than two electrons can occupy the same orbital and (2) two electrons in the same orbital must have opposite spins (Figure 46(i) and (ii)).
Which among the following Cannot accommodate more than 2 electrons?
An orbital cannot have more than two electrons. This is because two electrons in an atom cannot have the same set of all four quantum numbers. This is in accordance with Pauli’s exclusion principle. The two electrons in an orbital create opposite magnetic field as they have opposite spins.
Who discovered proton and neutron and electron?
Discovery of Electrons, Protons and Neutrons
| Discoverer | Year of Discovery | |
|---|---|---|
| Proton | E. Rutherford | 1909 |
| Neutron | James Chadwick | 1932 |
| Electron | J.J. Thomson | 1897 |
Can an orbital have more than 2 electrons?
[SOLVED] An orbital cannot have more than two electrons and they must have opposite spins. An orbital cannot have more than two electrons and they must have opposite spins. No two electrons in an atom can have same set of all the four quantum numbers as per Pauli’s exclusion principle.
Which statement is true of orbitals of equal energy?
“Orbitals of equal energy are each occupied by one electron before any is occupied by a second electron, and all electrons in singly occupied orbitals must have the same spin” is a statement of Hund’s rule The statement that no more than two electrons in the same atom can occupy a single orbital is the Pauli exclusion principle
Can two electrons of the same atom have the same quantum numbers?
In the case of electrons in atoms, it can be stated as follows: it is impossible for two electrons of a poly-electron atom to have the same values of the four quantum numbers: n, the principal quantum number, l, the angular momentum quantum number, m, the magnetic quantum number, and s, the spin quantum number.

What is the Hund’s rule for electron configuration?
Hund’s rule Two electrons in the 1s orbital must have different spin quantum numbers to satisfy the Pauli exclusion principle The sequence in which energy sublevels are filled is specified by
