Can I swap ETH for Arbitrum?

Could you please explain if it's possible for me to exchange Ethereum (ETH) for Arbitrum tokens? I'm interested in diversifying my cryptocurrency portfolio and have been eyeing Arbitrum as a potential addition. However, I'm not entirely sure how the swapping process works or if it's even feasible. Could you provide some clarity on this matter? Are there any specific exchanges or platforms that facilitate this kind of swap? Also, what are the potential risks and considerations I should be aware of before proceeding with such a transaction? Thank you for your assistance in clarifying this matter.
