When an atom with a sufficiently small radius sits in an interstitial “hole” in a metal lattice, a compound known as an interstitial compound or interstitial alloy is created. Carbon, nitrogen, boron, and hydrogen are a few examples of small atoms.

Corrosion is the natural transformation of a refined metal into a more stable state, like its oxide, hydroxide, or sulphide state, which causes the material to deteriorate. The chemical breakdown of metals brought on by the actions of the surrounding medium is known as corrosion.

K has a +1 charge, so K3 is +3. CN has a -1 charge, so (CN)6 is -6. So, +3 + -6 + x = 0 -3 + x = 0 x = +3 So, the oxidation state of ‘Fe’ in K3[Fe(CN)6] is +3.

The atomic number of chromium = 24. Cr (Z = 24) = 1s2, 2s2 2p6 3s2 3p6 4s1 3d5

By allocating oxidation numbers to the other elements and taking into account the compound’s total charge, the oxidation number of Mn in MnO4- can be determined.

Let x represent Mn’s oxidation number in MnO4-. Since the compound’s total charge is -1, we can construct the equation:

x + 4(-2) = -1

Making the equation simpler:

x – 8 = -1

x = -1 + 8.

x = +7

Consequently, Mn in MnO4-has an oxidation number of +7.

Option C is accurate because slag is formed by manganese, silicon, and phosphorus oxides when “wrought iron” is made from cast iron.

Because of their geometrical characteristics, lanthanides and actinides are commonly found on the surface of the earth, which is why they are referred to as “rare earth elements.”

Scandium has a partially filled d orbital because it is the first element in the 3d block of transition metals. Sc’s ionic chloride, which is created when an electron is transferred from Sc to Cl, and its capacity to form stable compounds in the +3 oxidation state are some characteristics that lend credence to this.

[PtCl(NO2)(NH3)4] has a coordination number of 6. The molecule’s six ligands bound to the Pt atom are the reason for this. Cl, NO2, and NH3 are the ligands.
