FAQ

What Is The Enthalpy Of Atomization?

Enthalpy of atomization is the amount of enthalpy change when a compound’s bonds are broken and the component atoms are separated into single atoms ( or monoatom). Enthalpy of atomization is denoted by the symbol ΔatH.

What Is Atomisation In Chemistry Class 12?

The definition of atomization may be taken from a sentence, which means “turning into atoms.” In the lab, chemical reactions are performed under continuous pressure, i.e. atmospheric pressure.

What Is Enthalpy Of Atomisation In 3d Series?

Assertion : In the series Sc to Zn, the enthalpy of atomisation of zinc is the lowest. Reason : Zinc has greater number of unpaired electrons. In the series Sc(Z = 21) to Zn(Z =30), the enthalpy of atomisation of zinc is lowest i.e., 126kJmol−1..

What Is The Definition Of Atomization In Chemistry?

Atomization refers to breaking bonds in some substance to obtain its constituent atoms in gas phase. By extension, it also means separating something into fine particles, for example: process of breaking bulk liquids into small droplets.
