yes it is
Sodium I think
No, sodium (Na) is more chemically reactive than lithium (Li) because sodium has an outer electron configuration that makes it more likely to lose an electron and form compounds.
Sodium is not considered chemically stable because it is highly reactive. It readily forms compounds with other elements, particularly halogens like chlorine, to achieve a more stable electron configuration. Sodium is stored under oil or in a dry environment to prevent its reactivity with air and moisture.
Yes, chlorine is chemically reactive. It is a highly reactive nonmetal and readily forms compounds with other elements.
When argon and sodium are mixed, they do not react chemically because argon is an inert gas and sodium is a highly reactive metal. The two substances would essentially remain separate in the mixture.
sodium is more reactive than magnesium!
Yes, sodium is extremely reactive.
Sodium chloride is not highly reactive.
A soft silvery metal, you can cut it with a knife.Do not touch it! Sodium should always be stored in mineral oil to prevent contact with air or moisture. It is dangerously chemically reactive!
Argon has completely filled valence orbitals and hence is unreactive. Sodium has one valence electron. If sodium loses this electron it will attain the stable electron configuration of the nearest noble gas (argon) and hence is reactive.
Unstable isotopes can be chemically reactive.
Manganese is not radioactive; chemically is sufficiently reactive.
