what do these words & phrase mean?1.retrodonation(in chemistry)2.Alternatively(at the begining of a sentese?

Answer 1

1. In a basic two-part chemical bonding, one part will be an electron donor, the other an electron acceptor. In some complex reactions, one part will act normally as an electron acceptor, but at another bond site in the same reaction it will be an electron donor - in other words, it gives back electrons. That is called retrodonation. That's a simplified explanation.

2. If 'Alternatively' is used at the beginning of a sentence, it means that the preceding sentence explained/talked about/described one way to do something and this new sentence is going to cover another way (an alternate) to do the same thing.
