Elements normally do not form "molecules" apart from 3 gaseous elements which form diatomic molecules. However, Sulfur exists in molecules comprising 8 atoms, while Phosphorous exists as a 4 atom molecule.
Pb the Lead is a metal so exists as the combination of atoms not the molecules.
No Hg, or mercury is an element, but it is not molecular.
Iron is an element that exists as atoms, not molecules. Each iron atom has 26 protons in its nucleus, giving it its atomic number. Diatomic molecules contain two atoms of the same element bonded together, which does not apply to iron.
No, iron is a metallic element and do not exists as molecules, macro molecules are those which contain thousands of atoms or molecules as a single unity as starch, proteins etc.
helium is an element, it is a mono atomic molecule, He2 .
No, it is most commonly regarded as tetratomic (tetra=4) molecule: P4
Pb the Lead is a metal so exists as the combination of atoms not the molecules.
A diatomic element exists as a molecule containing two of its atoms, such as chlorine (Cl2) and bromine (Br2). Elements that are not diatomic include monatomic elements (noble gases such as Ar, Ne) and triatomic elements (ozone, O3).
Oxygen is an element and so has its own unique type of atom. However, oxygen usually does not exists as individual atoms, but rather as O2 molecules, that is, molecules containing 2 oxygen atoms. O3 is another type of oxygen molecule know as ozone.
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.
Sulfur is NOT a diatomic element. Diatomic elements exist as molecules containing two atoms of the same element bound together, such as fluorine (F2), oxygen (O2), and hydrogen (H2). However, sulfur exists as S8 molecules in its elemental form, with eight sulfur atoms bonded together.
At standard temperature and pressure, nitrogen exists in molecules with two atoms each.
No Hg, or mercury is an element, but it is not molecular.
Iron is an element that exists as atoms, not molecules. Each iron atom has 26 protons in its nucleus, giving it its atomic number. Diatomic molecules contain two atoms of the same element bonded together, which does not apply to iron.
No, iron is a metallic element and do not exists as molecules, macro molecules are those which contain thousands of atoms or molecules as a single unity as starch, proteins etc.
Helium is a single atom element. It exists as individual atoms and does not form diatomic molecules, molecules, or formula units.
helium is an element, it is a mono atomic molecule, He2 .
