What else can I help you with?
Which metal is the most readily oxidated of all the elements?
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.
Which element is most reactive potassium or iron or alumimum?
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.
What are the most active groups in the periodic table?
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.
What are the most reactive metals called?
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.
Least reactive to most reactive elements Lithium potassium Rubidium.?
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.
What gas is the most reactive of all elements?
Francium is the most reactive metal and fluorine the most reactive nonmetal.
Would a metal in Group 13 be more or less reactive that a metal in Group 1?
less reactive.beacuse group-1 elements are the most reactive elements.
Which is the most reactive non-metal?
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.
If you mix chlorine lithium and nickel together which two elements would be the most reactive?
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.
What metal is the most reactive metal?
Fluorine is the most reactive non-metal.
What 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.
What is the most reactive metal and nonmetal group in the periodic table?
caesium is the most reactive non-radioactive metal and Florine is the most reactive non-metal, but francium is the most reactive, radioactive metal
What is the gas that metal reacts with?
Fluorine gas is one of the most reactive elements that exist and it will react with most metals.
Most reactive non metal?
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.
How do you find out what metal is the most reactive?
Metals which can easily loose electron are most reactive. They are present in group-1.
Which non metal below is most reactive?
fluorine is the most reactive non metal in the periodic table.
Where are the most reactive element found on the periodic table?
Group 1, or the alkali metals, left of the table and Group 17, the halogens, right of the table are the most reactive groups. Fr, or Francium (atomic number 87) is the most reactive metal- and fluorine the most reactive halogen. Francium and fluorine would react together explosively they are so reactive.
