ICSE Class 10: Electrovalent Bonding Videos | Writing Molecular Formulae_1

• generally the ionic compounds have high melting points
• How much power (IP) is needed to transfer one electron from one atom to another atom? 
• Why they are electro bond
• If i add Na and Cl artificially  , what will happen then Will it form common salt
• Ionic compounds are solids with high melting point give reason  
• Element X has 2 valence electrons ,element X has atomic number 7. A) Write equation to show how X and Y form ions. B) If B is a diatomic gas ,write the equation for the direct combination of X and Y to form a compound.
• what is electrovalence
• define ionisation potential 
• What is ionisation? Please explain in easy language. Why does ionisation take place? How can covalent compounds be converted into ions as they are composed of molecules?
• why electrovalent compounds dissolve in water but not in petrol
