There are several such elements. All of them are in group 13. Those elements are boron, aluminum, gallium, indium, and thallium.
there is only one unpaired electron in copper
3 electrons. This can be told from the periodic table. These electrons are in the 2p orbital.
3
Correct. Filled energy sublevels have electrons occupying all available orbitals within the sublevel, while partially filled sublevels have some orbitals unfilled. This is a result of the rules governing electron configuration in atoms.
An atom of aluminum in the ground state has 3 electrons in its valence shell. Aluminum has an electron configuration of 2-8-3, so its valence shell is the third shell, where the last 3 electrons reside.
Phosphorus has three unpaired electrons in its ground state.

Assuming the copper started at ground state, after gaining 3 electrons, it would have a charge of -3.
An atom of aluminum in the ground state has 3 electrons in its valence shell. Aluminum has an electron configuration of 2-8-3, so its valence shell is the third shell, where the last 3 electrons reside.
In its ground state, the Ga3+ ion has 0 electrons in its outermost shell. This is because the Ga3+ ion has lost three electrons from its neutral Ga atom configuration, which changes the electron distribution.
s contains one orbital with a maximum of 2 electrons p contains three orbitals with a maximum of 6 electrons d contains five orbitals with a maximum of 10 electrons f contains seven orbital with a maximum of 14 electrons
Titanium atoms have 22 electrons and the shell structure is 2.8. 10.2. The ground state electron configuration of ground state gaseous neutral titanium is [Ar]. 3d2.
Lithium has three electrons, two in the inner shell and a single one ouside that, so there are two energy levels. See the link below
There are three unpaired electrons in an atom of cobalt in its ground state. This can be determined by the electron configuration of cobalt, which is [Ar] 4s2 3d7. The 3d orbital has 5 electrons, so there are 3 unpaired electrons.
