You don't need to add the “dot” at the end of the name server. Make sure that in your Cloud DNS, A record is set and pointed correctly to your external IP address follow this link as a guidance on how you can set your A record.
Once you use the name server of cloud DNS and place it in your domain registrar DNS which is shown in your screenshot, the A record of your domain should be in Cloud DNS. Any record, should be on Cloud DNS.
To check, you can use this link if your domain is propagating, another way to check is to dig the domain. Place in the domain, click A from the link, it indicates the A record then check if external IP address is correct.
