A nickel atom has an atomic number of 28, which means it has 28 electrons. Its electron configuration is [Ar] 3d^8 4s^2. In this configuration, the 3d subshell contains 8 electrons, with 2 of them unpaired. Therefore, a nickel atom has 2 unpaired electrons.
Nickel (Ni) has an atomic number of 28, which means it has 28 electrons. Its electron configuration is [Ar] 3d^8 4s^2. In this configuration, the 3d subshell has 8 electrons, with 2 of them paired and 6 electrons remaining, resulting in 2 unpaired electrons. Therefore, nickel has 2 unpaired electrons.
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.
There are no unpaired electrons in strontium.
Barium has 0 unpaired electrons. It has a full outer shell of electrons, which is why it is a stable element.
