The ENDPOINT
A line with only one endpoint is a ray. One end has a point, and the other has an arrow to represent how the line continues forever.-------------------------->
Each point is called a vertex.

False. It could be the first letter.
True
Yes. If your ray's endpoint is the letter A and it goes on forever in the direction of the letter B, that is not the same as a ray that starts at the letter B and goes on forever in the direction of the letter A. So always name your ray starting with the endpoint letter.
When a symbol contains two letters, the first letter indicates the element's chemical symbol, while the second letter is always lowercase. This convention helps differentiate the symbol from potential elements with similar first letters.
