Germanium has 4 unpaired electrons.
There are three unpaired electrons in an arsenic atom. Arsenic has five valence electrons, with two paired and three unpaired electrons.
6 unpaired electrons
Xenon has eight unpaired electrons.

There is 1 unpaired electron in Copper (Cu)
There are no unpaired electrons in strontium.
Iron is magnetic because it has unpaired electrons in its outer shell that align in the presence of a magnetic field. Nickel and copper do not have as many unpaired electrons in their outer shell, making them non-magnetic under normal conditions.

Germanium has 4 unpaired electrons.
Aluminum has three unpaired electrons.
There are three unpaired electrons in an arsenic atom. Arsenic has five valence electrons, with two paired and three unpaired electrons.
Copper sulfate (CuSO₄) contains copper (Cu) in the +2 oxidation state. In this state, copper has an electron configuration of [Ar] 3d⁹, resulting in one unpaired electron in the 3d subshell. Therefore, the expected number of unpaired electrons in CuSO₄ is one.
6 unpaired electrons
Phosphorus has three unpaired electrons in its ground state.
Nickel has two unpaired electrons.
