Name and value clarification

Sorry if this is a silly question, and I hope my question is understood. Can someone clarify for me please, so in the case of adding images via <img src attribute, the img is the name of the attribute and the src is a value of the attribute right?

In simple terms, no. IMG is the tagname, or element type; src is the attribute name whose value is a source URL.

<img src="imageurl" alt="">
  |    \        \____ attribute value
 type  attribute name
