Explanation
A type of ion found in aluminum oxide is :
Explanation:
Hence, the correct answer is option A.
Whenever two electrons are paired together in an orbital, or their total spin is 0, they are diamagnetic electrons. Atoms with all diamagnetic electrons are called diamagnetic atoms.
A paramagnetic electron is an unpaired electron. NO has one unpaired electron. Hence, it is paramagnetic in nature.
Concentrated nitric acid is a powerful oxidising agent, and its reaction with zinc involves a complicated set of redox reactions. However the primary product is still zinc nitrate.
4Zn+10HNO3→4Zn(NO3)2+N2O+5H2O
Option (D) is correct.
H2 is not pseudo halogen compound.
The pseudohalogens are polyatomic analogues of halogens, whose chemistry, resembling that of the true halogens, allows them to substitute for halogens. They have a general formula of Ps–Ps or Ps–X (where Ps is a pseudohalogen group), such as cyanogen, pseudohalide anions, such as cyanide ion. Well-known pseudohalogen functional groups include cyanide, cyanate, thiocyanate, and azide.
