Question

Define & explain:
a) enthalpy of atomisation
b) enthalpy of ionisation​

Answer 1

Answer:

Climate is the long-term average of weather, typically averaged over a period of 30 years. More rigorously, it denotes the mean and variability of meteorological variables over a time spanning from months to millions of years. 

Answer 2

Answer:

1.The enthalpy of atomization is the enthalpy change that accompanies the total separation of all atoms in a chemical substance. This is often represented by the symbol ΔₐₜH or ΔHₐₜ. All bonds in the compound are broken in atomization and none are formed, so enthalpies of atomization are always positive.

2. Ionization Enthalpy of elements is the amount of energy that an isolated gaseous atom requires to lose an electron in its ground state. Losing of electrons results in the formation of cations. You need to provide a specific amount of energy to remove an electron from an atom.

ionisation energy is the amount of energy provided to extract an electron from the outermost shell of a neutral or ionic gaseous atom and ionisation enthalpy is the change in energy of the 1 mole of gaseous atoms or ions when the outermost electron is removed from the atoms or ions.
