This element has 8 protons, so element is oxygen. I recommend looking at the periodic table of elements. At standard temperature and pressure (STP), oxygen is a gas, so that puts it in the nonmetal category.
Side note: Metalloids are a collection of elements where they share properties of metals and nonmetals (in a way they're on the fence).

7x=28 divide both sides by 7
x=4
