Aluminum is an element, composed of molecules, is on the periodic chart, does exist by itself AND can be combined to form compounds.
A molecule of CH4 (methane) is more likely to exist in nature because it is a stable compound with all valence electrons satisfied through covalent bonding. A molecule of CH3, on the other hand, would be highly reactive due to the presence of an unpaired electron on the carbon atom, making it less likely to exist in nature.
Not at all. Aluminum oxide is a compound of aluminum, not an allotrope. An allotrope of aluminum would still be called aluminum, but sometimes we distinguish allotropes by assigning numbers, such as sulfur-1, sulfur-2, etc. It refers to the specific structure which the atoms form (such as crystaline vs. amorphous).
XeCl8 does not exist as a stable compound. Xenon typically forms compounds with a maximum coordination number of 6 due to its electron configuration, and the reported compound XeCl8 is likely a theoretical or unstable concept.
Iodine (I) does not exist as a diatomic molecule under normal conditions. While F (fluorine), Ne (neon), and H (hydrogen) exist naturally as diatomic molecules (F2, Ne2, H2), iodine typically exists as a monatomic molecule, I2.
Al3 plus and N3 combine ionically -well neither species exist but aluminum and nitrogen combine to make aluminum nitride - AlN.
Yes, elements and compounds can exist separately.
molecule
Aluminum is a pure element, so it does not exist as a compound. In compounds, aluminum can be found combined with other elements, such as oxygen in aluminum oxide (Al2O3) or chlorine in aluminum chloride (AlCl3).
Hydrogen is an element because it is made up of only one type of atom, which is hydrogen itself. When two hydrogen atoms bond together, they form a hydrogen molecule (H2). So, hydrogen can exist as both an element and a molecule.
You can control the number of water molecules that exist in a hydration compound by regulating the number of hydrogen and hydroxyl ions.
A molecule Ni3 doesn't exist; you think probable to a compound of Ni(III).
The compound Cl3 does not exist (did you mean chlorate?). Triatomic hydrogen H3 does exist however but is an unstable molecule.
A molecule is the combination of two or more atoms which may exist free in nature. Does this mean that one atom of heliom is NOT a molecule? yes it is not a molecule it is an atom that exists free as a molecule so the term monoatomic molecule is used for noble gase but not only molecule.
The compound HeNe exist but it is difficult to obtain this molecule and is very unstable.
The smallest particle of a compound that can exist and still retain the characteristic properties of that substance is a molecule. For gaseous elements, individual atoms are the smallest particle that retains the characteristic properties of the element.
Not necessarily. A molecule is the smallest unit of a chemical compound that can exist independently, while a compound is a substance made up of two or more different elements chemically bonded together. All compounds are molecules, but not all molecules are compounds.
A molecule is the smallest particle of a "compound" being that compounds are made up of more than one atom. The smallest particle of any "chemical element" that retains its properties would be the atom.
