More often than not, there are a lot of questions especially on the chemistry exchange telling "my textbook says so and so, but this makes no sense" like this one in particular . And for some reason, Chemists always look at contempt at these high school level questions. Yes the same question gives you answer on the internet but all of those are loosely based on what was given in the textbook, which was factually incorrect as pointed out by the users.
My reason for suggesting this is because a lot of users always ask for it, (like "oh you read somewhere? or do you mean from your textbook") and there are quite a lot of times where OP takes a few days to get back like the linked example. But as always it's up for the community to decide
