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

Aluminum has three unpaired electrons.
Germanium has 4 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.
