What determines if an element needs a closing tag?

I was wondering what determines if an element needs a closing tag or not. For example, input, br and hr don't support being closed with </element> but their structure is simply <element/> (although I prefer just <element>) - with attributes if needed.

Also, how would I replicate this behaviour in a custom element?

Their definition in the HTML specification.

but their structure is simply <element/>

The / is optional in HTML 5. It is only there for people who got used to the syntax when XHTML looked like the way forward.

Also, how would I replicate this behaviour in a custom element?

You can't. The custom element specification doesn't provide any means to make an end tag optional or forbidden.
