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.
YEP! remember In science in order for the Alkali metals and Alkaline earth metals to become stable they must give AWAY electrons. The Earth metals have a Plus 2 charge because they give away 2 electrons on there outer shell!
The alkaline earth metals are a series of elements comprising Group 2 (IUPAC style) (Group IIA) of the periodic table: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra). This specific group in the periodic table owes its name to their oxides that simply give basic alkaline solutions.
The earth has electric currents in its structure, that create magnetic fields.
The electron configuration is why they react. The Alkali metals have one electron in their outer shell and to complete their outer shell need 7 more electrons. They can give, take or share electrons with other atoms. This is when the Halogens come in handy. The Halogens have 7 electrons in their outer shells, and need one more to complete the outer shell. These can react very easily because they have both the perfect amounts to fill their outer shells and become compounds. Other atoms with other amounts to become atoms not ions needs another element to react with. Hope this helps, Matt.

For an uncombined atom, the oxidation number is 0. It does not give away any electrons. It does not accept electrons from anywhere either.
metals,gas,
They are the Alkali Metals, Alkaline Metals, Transition Metals, Metalloids, Halogens, and the Noble (Inert) Gases. There is also the lanthanide and actinide series which are known as the Rare Earth Metals.
Metals that lose electrons easily are called "reactive metals" or "electropositive metals." These metals have low ionization energies, which allow them to readily give up electrons to form positive ions.
They give up two valence electrons to have a full electron shell.
Groups 3-12 do not have individual names. Instead, all of these groups are called transition metals. The atoms of transition metals do not give away their electrons as easily as atoms of the Group 1 and Group 2 metals do. So, transition metals are less reactive than alkali metals and alkaline-earth metals are.
Alkaline earth metals, such as magnesium and calcium, do react with air. When exposed to oxygen, they form oxides or hydroxides on their surface, which can give them a characteristic dull appearance. The reactivity increases as you move down the group from beryllium to radium.

Eureka! I have found it! give me a place to stand, and I will move the earth.
Metals give up electrons while non-metals gain electrons
Group I (alkali metals) and Group II (alkaline earth metals) elements on the periodic table are more likely to give away electrons to form positive ions. These elements have one or two electrons in their outermost energy level, making it easier for them to lose these electrons and achieve a stable electron configuration.
