Can I buy Solana on MetaMask?

Could you please clarify for me, is it possible to purchase Solana tokens using MetaMask? I'm a bit confused about the process as I'm new to cryptocurrency trading. Could you provide some guidance on how to go about this? Are there any specific steps I need to follow or requirements I need to meet in order to make this purchase? Also, is there any risk involved in doing so, and how can I ensure the safety of my transactions? Thank you for your assistance in this matter.
