If an atom has all of it's outer orbitals filled it is non-reactive.
Yes, chlorine is chemically reactive. It is a highly reactive nonmetal and readily forms compounds with other elements.
Bromine is the most chemically reactive out of these elements because it has 7 valence electrons in its outer shell, making it highly likely to form bonds with other atoms to achieve a stable octet configuration. Conversely, elements like neon are inert gases with full outer shells and are therefore less chemically reactive.
Yes, nicotine is a reactive substance that interacts with various receptors in the brain, particularly nicotinic acetylcholine receptors. This interaction leads to the release of neurotransmitters such as dopamine, which contributes to its addictive properties.
Two valence electrons make an atom chemically reactive because it wants to either gain or lose electrons to achieve a full valence shell. This makes it more likely to form bonds with other atoms to reach a stable electron configuration.
Hydrogen
No. argon is chemically unreactive due to the presence of completely filled orbitals.
The anion has a negative electrical charge and is more chemically reactive than the atom.
the one that is completely filled
All the neutral atoms (except noble gases) are more reactive. To gain stability, they form ions; therefore, ions are less reactive.

Manganese is not radioactive; chemically is sufficiently reactive.
Unstable isotopes can be chemically reactive.
If all the electron orbitals are filled then the atom is inert. It will not chemically react with anything. If an atom has empty spaces in the outer orbit, it will react with other elements. Electrons from other elements can share positions in the outer orbits.
yes it is
yes
A single nitrogen atom can be chemically reactive while a nitrogen molecule is relatively stable and tends to be faf more inert. A nitrogen molecule also has twice the mass of a nitrogen atom.
