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.
yes they exsist as monoatomic molecule in vapour state
that would make it the gaseous atoms if they are exist in "monoatomic"molecules and the answer is yes.mercury vapor and sodium vapor lightening depend upon that fact
Elements, as in the Periodic Table of Elements, are each a collection of subatomic particles which have stuck together in a stable pattern to form an atom. If there were no elements and no atoms, then substances would not exist. There would be no Hydrogen, no Helium, no Lithium or any other element. And there would be no molecules, and there would be no organic chemistry and no people. The universe would thus consist of nothing but a swarm of unjoined sub-atomic particles. It would be invisible since no eye could exist to see it. And nobody would be present to witness or measure it.
The halogens are under group 17 (column 17) on the periodic table. They are in the column right next to the noble gases. They have the highest electronegativity values and typically exist as either anions or diatomic gases. Examples of these elements are fluorine, chlorine, bromine, and iodine.
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.
Radioactive elements exist in all groups of the periodic table.
There are a total of 118 elements known to exist on the periodic table.
Radioactive elements exist in all groups of the periodic table.

The nucleus consisting of Protons and Neutrons surrounded by one to several "shells" of orbiting electrons. The numbers of protons and neutrons for each element can be found in the periodic table of elements.
No, neon exists as a monatomic gas at standard temperature and pressure. It does not readily form diatomic molecules or other larger clusters like some other elements.
First of all it is a compound made of different elements, hence it cannot exist in periodic table. Periodic table is composed only of pure elements not in any combined form.
In the Periodic Table of the Elements, a column (group) contains all elements that exist with the group number of electrons in the outer energy level of an atom of that element.
No most of them are not isotopes. Few elements exist as isotopes.
