1) An element P forms a stable ion with the formula P$^{3+}$. P is in period 3 of the periodic table. (P is not the actual symbol of the element)
a) Write the electron arrangement of P$^{3+}$
Element P is in Period 3, meaning it has three electron shells.
It forms a stable ion P$^{3+}$, which means it has lost 3 electrons to achieve a stable noble gas electron configuration (an octet in its outermost shell).
A stable ion in Period 3 that has lost electrons would typically achieve the electron configuration of Neon (2.8).
If P
