Periodic Classification of Elements
For univalent elements, the average value of first ionization potential and first electron affinity is equal to its:
Write short notes on : Electronegativity
For univalent elements, the average value of first ionization potential and first electron affinity is equal to its:
Polarity of a bond can be explained by:
Consider the following changes: $$A\rightarrow A^++e^-: E_1$$ and $$A^+\rightarrow A^{2+}+e^-:E_2$$ The energy required to pull out the two electrons are $$E_1$$ and $$E_2$$ respectively. The correct relationship between two energies would be:
Why is $$sp$$ hybrid orbital more electronegative than $$sp^{2}$$ hybridised orbitals?
In a compound $$XY$$, if the electronegativity difference between $$X$$ and $$Y$$ is greater than 1.7, then the compound $$XY$$ is soluble in:
