P : $[Ne] 3s^23p^3$ Ge : $[Ar] 4s^23d^{10}4p^2$ Zr : $[Kr] 5s^24d^2$ I : $[Kr] 5s^24d^{10}5p^5$

#### Work Step by Step

P has 5 more electrons than its nearest noble gas, Neon. So, its electron configuration is: P : $[Ne] 3s^23p^3$ Ge has 14 more electrons than its nearest noble gas, Argon. So, its electron configuration is: Ge : $[Ar] 4s^23d^{10}4p^2$ Zr has 4 more electrons than its nearest noble gas, Krypton. So, its electron configuration is: Zr : $[Kr] 5s^24d^2$ I has 17 more electrons than its nearest noble gas, Krypton. So, its electron configuration is: I : $[Kr] 5s^24d^{10}5p^5$
