Strontium forms a compound with chlorine as SrCl2, where strontium has a +2 charge and chlorine has a -1 charge.

Strontium salts produce a red flame when burned.

Lithium salts produce a red flame when burned.

Alkaline earth metals typically exhibit a common oxidation state of +2.

Aluminum commonly exhibits an oxidation state of +3 in its compounds.

In Fe2O3, iron has a common oxidation state of +3.

The general electronic configuration of alkali metals is ns^1, where n is the principal quantum number.

Alkaline earth metals typically have a +2 oxidation state due to the loss of two electrons.

The thermal decomposition of calcium carbonate (CaCO3) produces calcium oxide (CaO) and carbon dioxide (CO2).

Lithium reacts with nitrogen to form lithium nitride (Li3N).

Calcium carbonate is commonly used in antacids to neutralize stomach acid.

Lithium is primarily used as an anode material in lithium-ion batteries due to its high electrochemical potential.

Magnesium is primarily used in the aerospace industry due to its lightweight and strength.

Magnesium is primarily used in construction and aerospace industries due to its lightweight and strength.

The atomic radius increases as you move down the alkali metal group due to the addition of electron shells.

The reactivity of alkali metals increases down the group due to the decrease in ionization energy.

Potassium (K) reacts vigorously with water, producing potassium hydroxide and hydrogen gas.

Beryllium has the highest melting point among the alkaline earth metals.

Magnesium is widely used in the production of lightweight alloys due to its low density.

Strontium (Sr) is used in fireworks to produce a bright red flame.

Strontium is used in fireworks to produce a bright red flame.

Potassium (K) is more reactive with water than Sodium (Na) and Lithium (Li).

Beryllium has the highest melting point among the alkaline earth metals.

Barium is the most reactive alkaline earth metal due to its larger atomic size and lower ionization energy.

Magnesium (Mg) is the least reactive among the alkaline earth metals due to its higher ionization energy compared to the others.

Calcium reacts vigorously with water to form calcium hydroxide and hydrogen gas.

Aluminum oxide (Al2O3) is an amphoteric oxide, meaning it can react with both acids and bases.
