Answer:
Frameshift mutations change the entire protein sequence and messes up the entire amino acid sequence that occurs after mutations, but substitution only changes one single amino acid.
Since Lithium has one valence electron that means it needs to lose it to form a stable structure. That means it's valence is equal to one. Oxygen has six atoms, in order to form a stable octet structure it needs to accept 2 electrons, therefore it's valence is 2.
Therefore two Lithium atoms bond with one oxygen atom to form Li2O
