Mono-atomic means: only one atom, so it is not bound to another and this is NOT a molecule.
When two or more (maybe up to thousands) atoms are bound together it is called a molecule
No, sodium is an element that exists as single atoms and not as molecules. Sodium is a monoatomic element because it consists of single atoms.
Liquid bromine is a monoatomic molecule as it is a liquid
Molecules, but sometimes Atoms in the case of the noble gases, which are monoatomic. They do not bond with other elements easily. Some examples of gas particles include O2 or H2O (as steam). A monoatomic gas such as He would have be a single atom as the particle. b i c h e z
No, Na and Hg in the vapor state do not exist as monoatomic molecules. They exist as diatomic molecules. Na exists as Na2 and Hg exists as Hg2 in the vapor state.
Sodium does not exist as molecules in the room temperature and pressure because it is a metal. Although it forms diatomic 'molecules' in gaseous phase at very high temperatures.
True. In their vapor state, both Na and Hg exist as monoatomic molecules, with Na being represented as Na and Hg as Hg. This is because in their gaseous form, both elements exist as individual atoms rather than diatomic molecules.
No. Helium is not molecular it is a monoatomic gas.
Argon gas is considered a monoatomic gas because its molecules consist of single atoms (argon atoms) that do not bond to form diatomic molecules like oxygen or nitrogen do. This means argon only exists as individual atoms in its gaseous state, whereas diatomic gases exist as pairs of atoms bonded together.
Yes. Argon is chemically inert due to the presence of completely filled orbitals. So it exists as a monoatomic species.
No, it is most commonly regarded as tetratomic (tetra=4) molecule: P4
Monoatomic means to have one atom. An anion is any ion that has a negative charge. An example of a monoatomic ion is S2- . Sulfur is the only atom in the atom, and it has a negative two charge.
molecules are made up of atoms There are monoatomic molecules as well. Helium is a monoatomic molecule. It produces a molecular ion in mass spectrometry.
