When it is stable. that is, all of it's electron shells are fully occupied.
Chlorine is the element most likely to react with aluminum, forming aluminum chloride through a chemical reaction.
Nobel gasses.
Chlorine is the element that will most likely react similarly to fluorine because they are both part of the halogen group, which are highly reactive nonmetals with similar chemical properties.
Chlorine is more likely to react with sodium. This reaction forms sodium chloride, a common salt.
Hydrogen fluoride is the most reactive compound in this group (not element).
The activity of an element refers to its reactivity or how likely it is to participate in chemical reactions. Elements with high activity readily form compounds, while those with low activity are less likely to react with other substances. The activity of an element is often influenced by its position on the periodic table.
i think the element will be lithium that's what i think
helium has completely filled orbitals and does not react with any element.
The ability of an element to react is determined by its reactivity, which is its tendency to undergo chemical reactions with other substances. Elements with high reactivity easily form compounds, while elements with low reactivity are less likely to react with other substances. Reactivity is influenced by factors such as the number of electrons in the outermost energy level of the atom.
The most reactive elements are alkali metals and halogens.
Neon does not react with other elements.
silver may or ot react with any element.........................i really don't know.....................
