Which element is mentioned in the opening line of the Boomtown Rats' hit 'I Don't Like Mondays'?

gillyoh, the song specifies the opening line, and the only element mentioned there is silicon. Gold is mentioned in the third line.

So gold is mentioned in the lyrics too. Not good answer options, there are many other elements to offer us.....

I think the lyrics are supposed to be 'daddy doesn't understand it' and 'what reason do you need to be sure'.
