How many elements does a compound have
WebHydrocarbons are organic molecules consisting entirely of carbon and hydrogen. We often use hydrocarbons in our daily lives: for instance, the propane in a gas grill and the butane in a lighter are both hydrocarbons. They make good fuels because their covalent bonds store a large amount of energy, which is released when the molecules are burned ... WebHeteronuclear molecules. All other diatomic molecules are chemical compounds of two different elements. Many elements can combine to form heteronuclear diatomic molecules, depending on temperature and pressure.. Examples are gases carbon monoxide (CO), nitric oxide (NO), and hydrogen chloride (HCl).. Many 1:1 binary compounds are not normally …
