Question

Name two ores of Iron. And give the sub- shell electronic configuration of Iron.

Answer 1

Name two ores of Iron.

Ans. Some of the ores of iron are hematite, magnetite, siderite, iron pyrites etc. Moreover, among all the ores of iron, magnetite is the finest quality iron ore.

Give the sub- shell electronic configuration of Iron.

Ans. In writing the electron configuration for Iron the first two electrons will go in the 1s orbital. After the 4s is full we put the remaining six electrons in the 3d orbital and end with 3d6. Therefore the Iron electron configuration will be 1s22s22p63s23p64s23d6.

Answer 2

Answer:

There are allotropic types of iron and they are called alpha, delta and gamma iron. Iron exhibits these three allotropic types at different temperatures when it cools the molded form. The electronic configuration of Fe 2+ is 1s 2 2s 2 2p 6 3s 2 3p 6 3d 6 and Fe 3 + is 1s 2 2s 2 2p 6 3s 2 3p 6 3d 5 .
