organic
The terms metal and non-metal are usually applied to the elements. Hydrogen fluoride is a covalent gas- it is a chemical compound.
Hydrogen is an element itself. It usually makes a covalent bond to make a hydrogen molecule. It is the lightest existing atom and compound respectively.
Carbohydrates consist of carbon, hydrogen, and oxygen, usually in a ratio of 1:2:1 as: (C1H2O1)n
Elements with intermediate electronegativities, such as carbon and hydrogen.
Usually not, but all elements have radioactive isotopes.
Usually carbon, hydrogen, and oxygen.
Hydrogen and oxygen are elements that usually take the form of molecules.
Of which elements? - Stars usually consist mainly of hydrogen, less helium, and small amounts of the so-called "metals" (which, in astronomy, means any heavier elements).Of which elements? - Stars usually consist mainly of hydrogen, less helium, and small amounts of the so-called "metals" (which, in astronomy, means any heavier elements).Of which elements? - Stars usually consist mainly of hydrogen, less helium, and small amounts of the so-called "metals" (which, in astronomy, means any heavier elements).Of which elements? - Stars usually consist mainly of hydrogen, less helium, and small amounts of the so-called "metals" (which, in astronomy, means any heavier elements).
Usually two : carbon & hydrogen.
The term is nuclear fusion, where light elements (usually hydrogen) fuse to form heavier elements.
Usually Hydrogen and Oxygen but also with other elements to a lesser extent.
Depends on the molecule. A water molecule is made up of oxygen and hydrogen. Those are the elements.
Carbon (C), hydrogen (H), and usually oxygen (O) are the three elements that commonly occur in organic molecules. Carbon is the central element in organic compounds, while hydrogen and oxygen are often present in varying quantities and arrangements, giving organic molecules their unique properties and functions.
Carbon, Hydrogen and Oxygen.
Carbon, hydrogen, and oxygen. A+
No, they are elements that usually exist as diatomic (two-atom) molecules in their elemental form.
