it is the lithium metal. it is less reactivated.
Calcium chloride contains an alkali earth metal (calcium, a group 2 element) and a halogen (chlorine). There is no alkali metal. Alkali metals are group 1 elements.
Sodium.
No, sodium is not a noble gas. It is a reactive metal that belongs to the alkali metal group in the periodic table. Noble gases are a group of non-reactive elements that include helium, neon, argon, krypton, xenon, and radon.
Francium is a radioactive alkali metal. It is highly reactive, and due to its extreme rarity and short half-life, it is difficult to study.
Hydrogen (H) is more reactive. Francium (Fr) is less reactive.
It is calcium.
This chemical element is francium (Fr).

Francium is a radioactive alkali metal. It is highly reactive, and due to its extreme rarity and short half-life, it is difficult to study.
No, the element antimony is a member of group 15 with nitrogen, phosphorus, arsenic and bismuth. It is a semi-metal. You may be thinking of Sr, strontium, which is a highly reactive member of the alkali metals.
reactivity of any element depends on its form.Ca reacts in its Ca+2 form and forms CaCo3 (Calcium carbonate)CaSo4(calcium sulphate) etc.
Potassium is a reactive metal, an alkali metal, placed in the group 1 of the periodic table, is soft, has a natural radioactive isotope, easily react with water and halogens, etc. The symbol is K.
In some cases yes but alkali metals are elements that have 2 valence electrons so they are very reactive. Some examples are Calcium and Radium.
Hydrogen (H) is more reactive. Francium (Fr) is less reactive.
Yes, calcium is a metallic element. It is a soft, silvery-white metal that is highly reactive and essential for various biological functions in the human body.
