Q. What is it called if an orbital holds two electrons?
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.
Q. Which quantum number states that each orbital can hold two electrons with opposite spins?
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)).

Q. What can hold 2 electrons?
s-orbitals can hold 2 electrons, the p-orbitals can hold 6 electrons. Thus, the second shell can have 8 electrons. The n=3 (third) shell has: The 3s orbital.
Q. Which rule principle states that each orbital has at most two electrons?
The Pauli exclusion principle states that an atomic orbital may describe at most two electrons. When electrons contain orbitals of equal energy, one electron enters each orbital until all the orbitals contain one electron with parallel spins. An atomic orbital may describe at most two electrons.
Q. When two electrons occupy the same orbital What must they have?
If two electrons occupy the same orbital they must have opposite spins. No two electrons in an atom can have the same four quantum numbers. Electrons with opposing spins are attracted to each other.
Q. Why is it that two electrons can use the same orbital?
Because electrons are fermions, the Pauli exclusion principle forbids these particles from having the same quantum numbers. Therefore, for two electrons to occupy the same orbital, and thereby have the same orbital quantum number, they must have different spin quantum number.
Q. When electrons are moving it is called?
Electron Flow / Electric Current. While the normal motion of “free” electrons in a conductor is random, with no particular direction or speed, electrons can be influenced to move in a coordinated fashion through a conductive material. This uniform motion of electrons is what we call electricity or electric current.
Q. Do electrons move clockwise or anticlockwise?
Electrons in an atom do not revolve around the nucleus. They don’t revolve clockwise. They don’t revolve counterclockwise.
Q. Do electrons rotate around themselves?
Orbital Motion: Electrons revolve around the nucleus of the atom. This is called electron orbital motion. Spin Motion: Electrons rotate on their own axis. This is called electron spin.
Q. Why do electrons rotate around the nucleus?
They move because electron have a lot of energy. Electron is rotate around the nucleus because nucleus have a heavy part and positive charge of the atom so nucleus is stationary and then electron is light part and negative charge with respect to nucleus and not more energy so electron move around the nucleus.
