Well, that's because argon is a noble gas. Noble gases are in group 18 of the Periodic Table. It's very stable, inert and unreactive because of its electronic structure, [Ne] 3s2 3p6. All its shells are fully filled with electrons - we say that it has the stable octet structure or noble gas configuration. That's why there is no necessity for argon to gain, lose or share electrons with other atoms, and even among argon atoms. So it exists as a monatomic atom, just one atom on its own. It just doesn't need to bond and can stay inert and stable just by its own.
No, it generally does not form chemical bonds because it is a noble gas.
The boiling points are very close.
A covalent bond.
covalent
In any diatomic element it is always a covalent bond.
yes carbon is formed with other carbon atoms
Argon
No. Argon has completely filled orbitals. It is stable and does not form compounds. Argon exists as monoatomic gas.
Argon is a noble gas and forms weak van der Waals bonds due to London dispersion forces. These bonds are relatively weak compared to other types of chemical bonding like covalent or ionic bonds.
No, calcium and argon cannot form a chemical bond with each other because argon is a noble gas and does not typically form chemical bonds. Calcium is a reactive metal that tends to form ionic bonds with nonmetals, but it does not form bonds with noble gases like argon.
they share electrons with the other atom they're combining with
Yes, hydrogen has one electron and will readily bond with other elements. Argon is an inert gas which does not bond with other elements easily.
A covalent bond is most likely to occur between nitrogen and oxygen. Both nitrogen and oxygen are nonmetals and have similar electronegativities, which promotes sharing of electrons in a covalent bond. Calcium and lithium, sodium and fluorine, and helium and argon are less likely to form covalent bonds due to differences in their electronegativities and ability to donate or accept electrons.
Atoms of elements have a fixed number of electrons that can bond with other atoms. Carbon has 4 electrons that can bond with other atoms. So 4 hydrogen atoms can bond with one carbon atom.
yes
To my knowledge argon is a noble gas, meaning it is extremely stable and very unlikely to bond. It may be I don't know enough but as a noble gas I believe it doesn't make bonds to other atoms.
No. Argon is chemically inert and does not form any bond with magnesium (or other metals).
Argon is a noble gas and exists as individual atoms, so it does not form bonds like other elements. It is a chemically inert gas and is most commonly found in its pure elemental form.
Atoms combine with other atoms to form compound. It makes the atoms stable.
