Copper has one unpaired electron.
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.
Strontium (Sr) has two unpaired electrons. It has an atomic number of 38, and its electron configuration is [Kr] 5s². The two electrons in the 5s subshell are paired, meaning there are no unpaired electrons in its ground state.
There are 2 unpaired electrons in a sulfur atom with an atomic number of 16. Sulfur has 6 electrons in its outer shell, and 4 of them are used to form covalent bonds, leaving 2 unpaired electrons.
three unpaired electrons
There are three unpaired electrons in an arsenic atom. Arsenic has five valence electrons, with two paired and three unpaired electrons.
Aluminum has three unpaired electrons.
Germanium has 4 unpaired electrons.
There are 2 unpaired electrons in a sulfur atom with atomic number 16. This is because sulfur has a total of 6 electron in its outermost shell, with 4 paired electrons and 2 unpaired electrons in its electron configuration.
6 unpaired electrons
