- Metallic bonds
- Drawing Lewis diagrams
- Predicting bond type (metals vs. nonmetals)
- Worked example: Lewis diagram of formaldehyde (CH₂O)
- Worked example: Lewis diagram of the cyanide ion (CN⁻)
- Exceptions to the octet rule

Ionic bonds: Reaction of metals & Non-metals
Metals and nonmetals react by transfer of electron. Created by Ram Prakash.

- We have the shells K,L,M,N. Are the number of shells just 4 or more than 4? If more than 4, what do we call them?(2 votes)
- There are atoms with more than 4 shells and those shells are called K, L, M, N, O, P, Q etc.(4 votes)
- Although magnesium chloride doesn't have any chlorine molecule, why is its formula MgCl2 and not MG2Cl?(1 vote)
- Because there are 2 molecules of chlorine not magnesium and magnesium has valency of 2 and that of chlorine is 1.So,1 magnesium molecule needs 2 chlorine molecules to get an inert gas configuration(5 votes)
- As all Ionic compounds are polar they form salts.
Salts(ionic compounds) are generally crystalline in nature and hence contain water of crystallization.
Why do ionic compounds form crystals when a specific amt. of water is added and not in their anhydrous form?(1 vote) - what are the maximum capacity of m shell and n shell?
why are octets stable and not reactive?
are there more shells like o shells, p shells?(1 vote)- The maximum capacity of the M shell is 18 and that of the N shell is 32.
Octets are stable because that's when the maximum capacity of the orbit is reached, i.e., there can't be more than 8 electrons in that orbit, so the atom becomes stable as it has reached its capacity.
There is an o shell, but I'm not too sure about a p shell(1 vote)
