Chlorine is an element, not a compound. Moreover, its a diatomic molecule, that is, a molecule of chlorine contains two atoms of chlorine.
2-butyne
In a covalent molecule, the name of the second element is modified by adding the suffix "-ide" to its root name. For example, in carbon dioxide (CO₂), the second element, oxygen, becomes "oxide." Additionally, prefixes are used to indicate the number of atoms of each element present in the molecule, such as "di-" for two in this case.
Two or more atoms of similar or different types combine to form a molecule. So, a combination of two atoms of oxygen is a molecule and not an atom. Oxygen is the name for both an element and a molecule. The molecule contains two atoms with a molecular fromula, O2 and is a gas at room temperature. The element oxygen or O is unstable and highly reactive. It is formed only briefly in some reactions.
The name of the compound dinitrogen tetrahydride implies that the formula of the compound is N2H4. Therefore, each molecule contains two nitrogen atoms and four hydrogen atoms.
The name of a molecule with two sulfur atoms is "disulfur"
NO!!!!! Hydrogen gas as represented in the Periodic Table has the symbol 'H'. As a gas it exists as the diatomic molecule (H2) (H - H) This is NOT a compound. A compound is a substance that consists of two or more different elements e.g. Water (H2O) or Carbon dioxide (CO2). NB A compound is a molecule However. NOT all molecules are compounds. e.g. A particle of water is a molecule and a compound. However, a particle of hydrogen is molecule , but NOT a compound.
That would be Hydrogen, whose name means, (Make water).
In a covalent molecule, the name of the second element is modified by adding the suffix "-ide" to its root name. For example, in water (H₂O), the second element, oxygen, is referred to as "oxide." Additionally, prefixes like "mono-", "di-", "tri-", etc., may be used to indicate the number of atoms present for both elements in the compound's name.
The name of Ne3s1 is "neon trioxide." It is a hypothetical molecule consisting of three oxygen atoms bonded to a neon atom, though it is not commonly encountered in chemical contexts due to the inert nature of neon.
No, "dixode" is definitely not an element. If the questioner meant "dioxide", that is also not an element, but rather is part of the name of inorganic compounds that contain two oxygen atoms per formula unit. Some persons might call the element oxygen "dioxygen", because it contains two atoms per molecule.
