Assuming "very reactive" to mean spontaneous and energetic in reaction, lower Alkaline metals are among the most reactive.
Alkaline metals are among the most reactive.
The elements in this group are called Alkali Metals.
Halogens.
Because they are all alkali-metals and alkali -metals are known for being very reactive.
Group 1 or alkali metals
Alkali metals are very reactive metals.
They are in the s block. Metals of the 1st group.
They are in the s block. Metals of the 1st group.
The elements in this group are called Alkali Metals.
Halogens.
Elements in the second group have 2 outer shell electrons and also very reactive. What are they called?
group 1, alkali metals
Group-1 includee soft metals. They are reactive with air and water.
Because they are all alkali-metals and alkali -metals are known for being very reactive.
Alkali metals
Group 1 or alkali metals
Alkali metals are very reactive metals.
The first group of the periodic table contains the reactive alkali metals: lithium, sodium, potassium, rubidium, cesium, and francium.
