Group 17, the halogens
Fluorine is a nonmetal. It belongs to the halogen group in the periodic table, which consists of highly reactive nonmetallic elements.
The elements from the group 12 are not the most reactive chemical elements.
Group 17, also known as the halogens, consists of the elements fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). In order from least reactive to most reactive, the elements are iodine, bromine, chlorine, and fluorine, with astatine being the least reactive among them. Fluorine is the most reactive halogen due to its high electronegativity and small atomic size.
Group 1 elements are more reactive than that of group 2 elements.
Assuming that "least nonmetallic" means the same as "most metallic", francium.
less reactive.beacuse group-1 elements are the most reactive elements.
You would look for a very reactive atom in group 1, also known as the alkali metals. These elements have one electron in their outermost shell, making them highly reactive as they easily lose this electron to form positive ions. Group 18, on the other hand, consists of the noble gases which are highly stable and unreactive due to having a full outer shell of electrons.
Reactivity increases as you go down the group. Radiom is far more reactive than Beryllium.
Group 2 elements of the periodic table have a 2+ charge and are reactive. These elements include beryllium, magnesium, calcium, strontium, barium, and radium. They readily form 2+ cations by losing two electrons in chemical reactions.
The elements in group 1 become more reactive as you go down the group.
all the elements of group 18 are Nobel gases. They are very very less reactive.
The reactive group of all metals consists of elements located in Group 1 and Group 2 of the periodic table, known as the alkali metals and alkaline earth metals, respectively. These metals are highly reactive due to their tendency to lose electrons and form positive ions.
