Answer:
D. 1s2,2s2,2p6,3s2,3p6,3d10,4s2,4p6,4d10,5s2,5p6
Explanation:
Hello!
In this case, since the standard iodine atom has 53 electrons, when it forms the iodide ion it is known it gains one spare electron so now it has 54; it means we need to write the new electron configuration up to 54 as shown below:
Thus, the answer should be:
D. 1s2,2s2,2p6,3s2,3p6,3d10,4s2,4p6,4d10,5s2,5p6
Even when the order is not the adequate one.

Answer:
sodium and chlorine.......
Answer:
0.00182 cm
Explanation:
Area of the aluminum foil = 22.86 cm ×22.86 cm = 522.58 cm^2
Density = mass/area × thickness
Density × area × thickness = mass
Thickness = mass/ Density × area
Thickness = 2.568 g/2.70 g/cm^3 × 522.58 cm^2
Thickness= 0.00182 cm
Answer:
Copper
