Why open only one tag <script> doesn’t work properly? I know it’s not the same thing as Stylesheets of CSS:
<link rel="stylesheet" href="assets/css/bootstrap.min.css" />
But why it is necessary to open and close the tag <script>, where I don’t report anything inside the tag? Isn’t that wrong? Or is there any situation where I pass some information to tag ?
<script src="assets/js/bootstrap.min.js"></script> // Sucesso
<script src="assets/js/bootstrap.min.js"> // Erro

What defines the document syntax requirements is called "DTD - Document Type Definition "
In his specification(18.2.1 The SCRIPT element) contains that definition clearly :
Start tag: required, End tag: required

Just look at the definition of the tag to understand.
Your example uses src to load an external script, but if you put the code between the tags, it also works. See the reference here
This is an example:
<script>
document.getElementById("demo").innerHTML = "Hello JavaScript!";
</script>

In cases where all information is present in attributes, as in your example with link, just close the tag with />.
