Sulfur has six electrons in its third electron shell.


Why copper is a conductor?

Copper has two electrons in the innermost shell, eight in the next shell, eighteen in the third shell, and one in the fourth shell. This means that the first three shells each have as many electrons as they can hold, and the fourth shell has one lonely electron. (The fourth shell can hold up to 32 electrons.) Because this one lonely electron is all by itself in the outer shell, it can easily separate from the rest of the atom and go roaming around, which makes copper a very good conductor

In an atomic structure how many atoms are allowed in each shell?

To determine how many electrons are in each shell (or energy level), you simply take two times the number of the shell or level squared. Two electrons are allowed in the first shell, eight in the second shell, eighteen in the third shell, thirty two in the fourth shell, fifty in the fifth shell, seventy two in the fifth shell, and so on.
