If m sub l is three, then there can be 7 orbitals, since the l value (the one that corresponds to the orbitals) would be 3 (denoting the f orbital).
One Mn atom contains 5 electrons in it's 3d subshell, all of which are unpaired.
Scandium has 1 3d electron.
On the periodic chart, the element with 5 electrons in its 3d orbital can be quickly identified. Elements with partially filled d-orbitals are located in the middle section, the "transitional metals." 3d is the first d-orbital, so we look in the first row of the middle section. This section fills the orbital by one more electron per element, so the one with 5 electrons is the fifth from the left.... Manganese! Atomic number 25.
Chromium is the exception to the aufbau principle. Instead of filling its 4s orbital before the 3d orbitals, one electron goes into the 3d orbital first. This anomaly is due to the more stable half-filled or fully-filled d subshell configuration in the 3d orbitals for chromium ions.
The atom represented in the orbital diagram 1s2s2p is carbon (C). This notation indicates the electron configuration of carbon, where the 1s subshell is filled with 2 electrons, followed by 2 electrons in the 2s subshell and 2 electrons in the 2p subshell.
In theory all elements have all the orbitals. Zinc has electrons in four of them.
Two electrons can occupy the 2s subshell, and 8 electrons can occupy the 3d subshell.
One Mn atom contains 5 electrons in it's 3d subshell, all of which are unpaired.
3d orbitals do exist and 2d orbitals dont exist because of the pauli exclusion principle which says only 6 electrons can exist in the 2nd shell, and you need at least 7 to get a d subshell
The number of electrons in a subshell of a copper atom depends on which subshell you are referring to. Copper has 29 electrons, so its electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2 3d9. The 3d subshell in copper contains 9 electrons.
Scandium has 1 3d electron.

An individual 3d orbital can hold only 2 electrons There are five 3d orbitals each of which can hold a maximum of two, making a maximum in the 3d subshell of 10 electrons.
