Cesium. Cesium is the bad boy of the alkali metals, a period that's just jam-packed with seriously nasty elements. Cesium is reactive enough that if you were to put some water into dry ice, and wait till the ice got that cold itself before putting some cesium on it, the cesium would still react with it!
Here's a remembrance: the higher an alkali metal's atomic number, the more reactive it is.
Potassium is more reactive than lithium, which is more reactive than sodium. This trend is based on the alkali metal group's reactivity, with reactivity increasing as you move down the group due to the decreasing ionization energy and increasing atomic size.
Iron is the odd one out because it is a transition metal, while lithium, potassium, and sodium are alkali metals.
Iron is the odd one out because it is a transition metal, while lithium, sodium, and potassium are alkali metals.
sodium, calcium, magnesium, aluminium, zinc, iron, tin and led are metals more reactive than hydrogen.
All of the alkali metals, the alkaline earth metals heavier than magnesium, and the halogens fluorine and chlorine are all highly reactive with water itself.
Reactivity increase down the group.Ceasium is the most reactive.
Potassium is more reactive than lithium, which is more reactive than sodium. This trend is based on the alkali metal group's reactivity, with reactivity increasing as you move down the group due to the decreasing ionization energy and increasing atomic size.
Any of the alkali metals: lithium, sodium, potassium, etc.
Yes, along with Sodium, Potassium, Rubidium, Cesium and Francium, Lithium is an alkali metal.
Hydrogen (H) is more reactive. Francium (Fr) is less reactive.
Iron is the odd one out because it is a transition metal, while lithium, potassium, and sodium are alkali metals.
Lithium, sodium, and potassium belong to the alkali metal family in the periodic table. They share similar chemical properties such as being highly reactive and easily forming ions with a +1 charge.
Iron is the odd one out because it is a transition metal, while lithium, sodium, and potassium are alkali metals.
sodium, calcium, magnesium, aluminium, zinc, iron, tin and led are metals more reactive than hydrogen.
The alkali metal family consists of the elements lithium, sodium, potassium, rubidium, cesium, and francium. These elements share similar chemical properties, including being highly reactive and forming alkaline solutions when they react with water.
Iron rusts with water the more reactive metals react for the oxygen in a displacement the less reactive metals there is no reaction hope this helps x
Lithium, sodium, potassium, in order of lighter to heavier
