If the spin of one electron in an orbital is spin-up, what is the spin of the other electron in that orbital?

Electron spin is an intrinsic property of an electron in which it exists in what is known as two distinct spin states, one known as "spin up" and the other,...

The correct answer is d) B⁴⁺ has the lowest energy ground state. Bohr's equation is $E_n = -(Z^2R)/n^2$ For the ground state, $n = 1$, so $E_1 = -Z^2R$ If...

Spin has zero bearing on repulsions or attractions. They will repel each other whether they have the same spin or not, because all electrons have the same charge. Having two...

Because of how there IS only one electron in $"H"$ atom. That single electron does not introduce orbital anguar momentum, so no matter what value of $l$, the orbital energies...

The 2 s and 2 p orbitals differ in shape, number, and energy. A 2 s orbital is spherical, and there is only one of them. A 2 p orbital...

The 2s and 2p orbitals have the same average distance from the nucleus. This would give them the same energy level. However the 2s orbital is a simple spherical...

4p is a higher energy level than 3p

According to ligand field theory, electron-electron repulsion causes normally degenerate orbitals to split. Ligand fields contact orbitals of the central atom; the orbitals that directly contact the ligand fields end...

Think of the quantum number l as the number of nodes in the electron wave function. For l = 0, there are no nodes, so you have a single...

The of $K$ is: $1s^2,2s^2, 2p^6,3s^2,3p^6,4s^1$ An atom will lose electrons from its last or furthest orbital from the nucleus. The furthest orbital in $K$ is $4s$, so the electron...
