Question

Which element has 10 electrons in its 3+ state?

Answer 1

this element is aluminum (Al). It is a metal of the group 13 (boron group), p-block of the third period of the periodic system. Its atomic number (Z) is 13, so its atom contains 13 electrons. In the compounds aluminum mainly occurs in the form of Al3+ ion or its complexes, i.e. it loses three electrons and has 10 electrons in its 3+ state.
