16. Sulphur
17. Chlorine
18. Argon
19. Potassium
20. Calcium
Lithium is the most readily oxidized metal among all the elements. It is very reactive and easily forms lithium oxide when exposed to air or moisture.
Potassium is the most reactive element among potassium, iron, and aluminum. It is a highly reactive alkali metal that readily reacts with water and air. Iron is moderately reactive, while aluminum is reactive but forms a protective oxide layer that prevents further reaction with the environment.
The most active groups in the periodic table are Group 1 (alkali metals) and Group 17 (halogens). Alkali metals are highly reactive due to their tendency to lose an electron, while halogens are highly reactive due to their tendency to gain an electron to achieve a full outer shell.
The most reactive metals are called alkali metals. This group includes elements like lithium, sodium, and potassium, which readily react with other elements due to their low ionization energy and tendency to lose an electron to achieve a stable electron configuration.
Rubidium is the least reactive, followed by potassium, and then lithium. This trend is due to the increase in reactivity as you move down the alkali metal group on the periodic table, with larger atoms having more easily discarded outer electrons, making them more reactive.
Francium is the most reactive metal and fluorine the most reactive nonmetal.
less reactive.beacuse group-1 elements are the most reactive elements.
Fluorine is the most reactive non-metal due to its high electronegativity and small atomic size, which makes it highly reactive in forming bonds with other elements.
Chlorine and lithium would be the most reactive because chlorine is a halogen and lithium is an alkali metal, both of which are highly reactive elements. Nickel is a transition metal and is less reactive compared to chlorine and lithium.
The placement of the elements from least reactive to most reactive is xenon, nickel, and then lithium. Xenon is a noble gas and is generally unreactive, while nickel, a transition metal, has moderate reactivity. Lithium, an alkali metal, is highly reactive, especially with water and air.
Fluorine is the most reactive non-metal.
The most reactive non-metal is fluorine. It is often nicknamed the 'Tyrannosaurus Rex' of the elements because of its reactivity. NB . Oxygen ,which we breath, is also a very reactive element. If it wasn't so reactive we would probably die.
caesium is the most reactive non-radioactive metal and Florine is the most reactive non-metal, but francium is the most reactive, radioactive metal
Fluorine gas is one of the most reactive elements that exist and it will react with most metals.
The most reactive nonmetals are the Halogens, found in group 17. These elements tend to have 7 electrons in their outermost energy level (valence electrons). Since they only need one more electron to stabilize, they react easily to form a negative ion.
Metals which can easily loose electron are most reactive. They are present in group-1.
fluorine is the most reactive non metal in the periodic table.
