Question

Give any two properties which differentiate alkali metals from alkaline earth metals..​

Answer 1

Answer:

ABOUT ALKALI AND ALKALINE:

Alkali: Alkali metals are softer. Alkaline: Alkaline earth metals are harder. Alkali: Alkali elements have one valence electron. Alkaline: Alkaline earth metals have two valence electrons.

PROPERTIES OF ALKALI:

• Found in column 1A of the periodic table.
• Have one electron in their outermost layer of electrons.
• Easily ionized.
• Silvery, soft, and not dense.
• Low melting points.
• Incredibly reactive.
