The full valence shell means that they do not react in chemical bonding.
The main purposes of chemical bonding is to obtain a stable structure.
Since the valence shell is stable,there is no need for chemical bonding since the whole atom is stable.
Answer:
Ideal machines are said to have parts which are weightless , frictionless and strings if any are inextensible. Practical machines have parts which have weights, friction and it causes some loss of work done. So these are the differences between Ideal Machine and Practical Machines.
