What are the chemical families on the periodic table?
Well, several are, and from left to right. Alkali metals Alkaline earth metals. Transition metals. Metaloids. Nonmetals. Halogens. Nobel gasses.
The three main groups of elements are?
The three main groups of elements are metals, nonmetals, and metalloids. Metals are typically solid, shiny, malleable, and good conductors of electricity. Nonmetals are generally dull, brittle, and poor conductors of electricity. Metalloids have properties that are intermediate between metals and nonmetals.
How chemically active are alkali metals?
Alkali metals are the most reactive metals.
What are more reactive alkali metals or alkline earth metals?
alkali metals
Is alkali the only earth metal?
No, alkali metals are not the only earth metals. Earth metals include both alkali metals and alkaline earth metals. Alkaline earth metals are a group of elements in the periodic table that are chemically similar to, but less reactive than, alkali metals. Examples of alkaline earth metals include magnesium, calcium, and barium.
How are alkali metals different any from other metals?
Alkali metals are very reactive metals.
How do alkali metals react with other alkali metals?
They don't
Why are earth alkali metals called earth alkali metals?
Alkali earth metals are named after their oxides, alkaline earth.
What are the group of soft silvery reactive metals known as?
