There are three elements. They are carbon,oxygen and hydrogen
If a material contains three elements joined in a fixed proportion, then it is a compound. It can only be separated by a chemical reaction.
A three-letter chemical symbol represents an element in the periodic table. Each element is assigned a unique symbol comprised of one to three letters. These symbols are used in chemical formulas and equations to represent specific elements.
Three elements that have similar chemical properties to oxygen are sulfur, selenium, and tellurium. These elements belong to the same group as oxygen in the periodic table and have similar electron configurations, which influence their reactivity and chemical behavior. Additionally, they can form similar types of chemical bonds with other elements.

Hydrogen is a gas, nonmetal, considered by IUPAC a member of the group I of the periodic table of elements.
No, they are three of the elements.
You get a copy and pin it to your wall. All the elements are arrange on it in a sensible way, summarizing their physical and chemical attributes. As you get familiar with it you will be able to use it to predict the chemical and physical properties of new elements you are to be taught about.
Three elements are present: calcium, carbon and oxygen.
Metals nonmetals and metalliods
