Question

for the group of four atoms or ions provided below, please select the species that are isoelectronic with each other. if none of the species are isoelectronic, please select the none of these species are isoelectronic button. check all that apply. □zn²⁺ □cu⁺ □ge²⁺ □se²⁻ □none of these species are isoelectronic

Explanation:

Step1: Determine electrons in Zn²⁺

Zinc (Zn) has atomic number 30. Zn²⁺ has 30 - 2=28 electrons.

Step2: Determine electrons in Cu⁺

Copper (Cu) has atomic number 29. Cu⁺ has 29 - 1 = 28 electrons.

Step3: Determine electrons in Ge²⁺

Germanium (Ge) has atomic number 32. Ge²⁺ has 32 - 2=30 electrons.

Step4: Determine electrons in Se²⁻

Selenium (Se) has atomic number 34. Se²⁻ has 34+ 2 = 36 electrons.

Answer:

Zn²⁺, Cu⁺
