Hello! How can I help you today?
assistant
I'm learning about chemistry in school, and I was wondering what the periodic table is.
user
The periodic table is a chart that organizes all the known elements, which are the building blocks of everything around us. It shows how the elements are related to each other and their properties.
assistant
That sounds interesting. What's an example of an element?
user
An example of an element is oxygen. It's a gas that we need to breathe to stay alive. Oxygen is represented by the symbol "O" on the periodic table.
assistant
I see. How many elements are there on the periodic table?
user
There are currently 118 known elements on the periodic table. New elements are sometimes discovered and added to the table.
