yes
Highly reactive because they only have 7 electrons. They need 8 to be a stable element.
Plutonium is a reactive chemical element.
They tell you how reactive the element is. If the atom has only one electron, then it is highly reactive. If the valence shell is full, then it will not react with other elements.
in the periodic table s block element except be and mg are highly reactive element . the reactivity increase from top to bottom and the element of lithium famil is more reactive than the the the beryllium family. cs is more reactive in s block element . they are most powerful reducing agent /
Gold.

A reactive non metal is an element that can gain the electrons or is more electronegative
Plutonium is a reactive chemical element.
Chlorine is a highly reactive element

bromine!
Alkali metals have only 1 electron in their outermost (ultimate) shell. This means the atom needs energy to loose only one electron to have a completely filled outermost shell. Other atoms with 2 or 3 electrons would have needed more than twice or thrice the energy than these to loose electrons. Hence alkali metals are highly reactive compared to others. Like alkali metals, who need to LOOSE 1 electron to have a completely filled outermost shell, halogens need to GAIN 1 electron to have a completely filled outermost shell. With the same theory mentioned above, they are highly reactive.

Chlorine is highly reactive.
rubidium
Chlorine is a Highly reactive element.
Because their outermost energy level is only partially filled, some elements are highly reactive, I believe.
