To see the elements of chemical substances (different metal fragments) in one place signifies a faithful friend, helpful science, a lady who is suitable for her situation or a good son.

Seeing that you are working in a chemistry laboratory is proof that you will develop your life with a thousand difficulties in a wider way in the future and that your earnings will increase to that extent.
