The HTML element used to create an unordered list is <ul>.
An unordered list presents a group of related items whose sequence is not inherently ranked. Browsers commonly render its items with bullets, although CSS can change the marker style, remove it, or replace it with another visual treatment. The list itself is created with <ul> and </ul>.
Each individual entry belongs inside an <li> element, so a basic list uses a structure such as <ul><li>First item</li><li>Second item</li></ul>. The <li> tag defines a list item; it does not create the list container by itself.
The main mix-up is between <ul> and <ol>. Use <ol> when order matters, such as numbered instructions or rankings. <dl> is for description lists, pairing terms with descriptions. The bullets are default presentation, not the meaning of the element: “unordered” refers to the absence of an ordered sequence, not to a lack of structure.
