Why do nuclear mass tables usually start with atomic numbers larger than 8?

for example see following article:

They don't. One example does not mean "usually".

I have read about 10 such articles.

You're posting nonsense.

In this very thread, you linked to a set of tables that started at A=1.

I did not say that it never starts with Z=1.

My question is why in many articles starting at Z&N= 8

Still not usual. The lists I use to use contain all elements. So in certain cases, it might make no sense to talk about light elements, or it's due to layout reasons, whatsoever. The fact, that you ask, makes me think, you suggest some underlying, hidden meaning. There is none. If someone created a list which starts with oxygen, so it's this someone whom you should ask. Otherwise it's simply guesswork about the author's intentions.

The answer to your question is: human pattern recognition, no correlation to chemistry or physics.
