The partial (valence-level) orbital diagram for a 2 ion is shown below. arrowuparrowdown arrowuparrowdown arrowuparrowdown arrowup arrowup (2 ion) 5s 4d write the symbol of the element from which this ion is derived. write the formula of the oxide this ion forms.

Answer 1

The 2+ ion is derived from Zinc (Zn), which loses two electrons to form Zn2+. The corresponding oxide formed is zinc oxide (ZnO).

Step-by-step explanation:

The question asks to identify the element from which a 2+ ion is derived based on the given partial orbital diagram and then to write the formula of the oxide this ion forms. The provided orbital diagram includes five arrows, indicating ten electrons in the corresponding orbitals. The diagram shows a fully occupied 5s orbital and four electrons in the 4d orbitals. This electron configuration corresponds to the element Zinc (Zn), which has an atomic number of 30. The 2+ icon denotes that zinc has lost two electrons, thus the electron configuration corresponds to the neutral Zinc atom, [Ar] 3d10 4s2. As for the oxide it forms, Zinc typically forms ZnO, which is zinc oxide.
