Is the alkali metal more reactive than an alkaline-earth metal?
Yes, alkali metals are more reactive than alkaline-earth metals. All atoms want to have 8 electrons in their outer shells. Alkali metals have to give one electron away, where as alkaline-earth metals need to give two away which is less energetically favorable.
Is sodium a halogen a noble gas a alkali metal or a alkaline earth metal element?
It is located, in the periodic table, with the metalloids. However, it is a transition metal.
Which member of alkaline earth metal is least reactive?
Look at any periodic table: Beryllium #4 Magnesium #12 Calcium #20 Strontium #38 Barium #56 Radium #88
What groups is the most reactive alkaline earth or alkali or halogens or noble gases?
I think alkali is the most reactive one.
In the alkaline earth group atoms with the smallest radii are?
they are most reactive
Most reactive alkaline earth metal?
Radium

Why is the magnesium the most reactive metal among silver copper lead zinc and iron?
magnesium is an alkaline earth metal. silver, copper, lead, zinc, and iron are transition metals. alkaline earths are naturally more reactive then transition metals.
What element potassium iron or aluminum is most reactive?
Potassium is the most reactive. It is in the 1st group. It is an alkaline metal.
What metal family is the most reactive in the periodic table?
Alkaline metals (Group 1) are the most reactive metals.
What element from potassium iron or aluminum is most reactive?
Potassium is the most reactive. It is in the 1st group. It is an alkaline metal.

What is the most reactive earth metal?
Radium is the most reactive in this group.
Why do you think the most commonly used metal objects of transitional metals rather than alkali metals or alkaline earth metals?
Alkali and alkaline earth metals are too chemically reactive to stay in metallic form.
What groups is the most reactive alkaline earth or alkali or halogens or noble gases?
I think alkali is the most reactive one.
In the alkaline earth group atoms with the smallest radii are?
they are most reactive
