Are polonium, livermorium, tennessine, oganesson all metals or only some

Polonium, Livermorium and Tennesine are metals.

Oganesson is not a metal.

Explanation:

Metals are elements that present themselves solidly at room temperature, in addition to having a silvery, metallic effect. They have crystalline anatomy and the ability to conduct electricity. All metals have high gloss, malleability, ductility, conductivity, melting and boiling points. Examples of metals are: Polonium, livermorium and Tennessine.

Elements characterized as non-metals are plentiful in nature and have characteristics such as not having a shine, being a bad conductor of heat and electricity, being a great insulator, breaking easily and having low melting and boiling points. An example of a non-metal element is Oganesson.
