can i download zoom on chromebook?

It would appear that yes, there is a Zoom client for Chrome OK. I've never used it so I can't comment. https://chrome.google.com/webstore/detail/zoom/hmbjbjdpkobdjplfobhljndfdfdipjhg?hl=en

Hi @sandrag8 , 

As @PaulTUK mentioned, we do have a specific Zoom for ChromeOS client, but due to the Chrome team ending support for those types of apps within the next year or so, we are moving away from that version. Instead, we are focusing on the new PWA (Progressive Web App), which already has the same functionality as the ChromeOS app, and more! Here is some more information about that version, which can be run in Chrome on any laptop. 

Hope that helps and please make sure to mark the solution as accepted if this information is what you needed.
