Properties of Ionic and Covalent Compounds

List the factors that determine the type of bond that will be formed between two atoms.

Collect the information about properties and uses of covalent compounds and prepare a report.

Predict the reasons for low melting point for covalent compounds when compared with ionic compound.

How bond energies and bond lengths of molecule helps us in predicting their chemical properties? Explain with examples.

$\mathrm{A}, \mathrm{B}$ and $\mathrm{C}$ are three elements with atomic number $6, 11$ and $17$ respectively.

Which of these can form ionic as well as covalent bonds? 

$\mathrm{A}, \mathrm{B}$ and $\mathrm{C}$ are three elements with atomic number $6, 11$ and $17$ respectively.

Which of these cannot form covalent bond? Why?

$\mathrm{A}, \mathrm{B}$ and $\mathrm{C}$ are three elements with atomic number $6, 11$ and $17$ respectively.

Which of these cannot form ionic bond? Why?

Why do only valence electrons involve in bond formation? Why not electrons of inner shells? Explain.
