Why are the alkaline earth metals less reactive hen the alkali metals?
The alkaline earth metals are in group 2 of the periodic table this means they have 2 electrons in each of their outermost energy 'shells'. The alkaline metals are in group 1 and only have 1 electron to lose in a reaction rather than 2. This means the alkaline metals react more readily.
A family of elements that has two electrons in its outer energy level is?
They are the alkaline metals.
Elements in group 2 are called?
Group 2 elements in the periodic table are the alkaline earth metals.
What are Group 2 called?
Alkaline Earth Metals
Why are group 2 metals classified as alkaline earth metals?
as most of the metals of group 2 are found in earth soil in large amount and they are alkaline metals. This is the main reason for calling alkaline earth metals.
What element has 2 valence electrons and 4 energy levels?
The element magnesium has four electron energy levels and two electrons in its outer energy level in the neutral atom. Use the link to Wikipedia for more details.
Is the ionization energy of alkali metals larger or smaller than the alkaline earth metals in the same period?
It is about first ionization energy. It is less than alkaline earth metals.
What is the name for metals with two electrons in the outer energy level?
They are called Alkaline Earth Metals

Which are products of the alkaline and earth alkaline metals combustion?
Alkaline metals and alkaline earth metals form their oxides when burnt. These oxides are base.
What elements has 2 main energy levels and seven valence electrons?
Alkaline earth elements have two valence electrons Those are the alkaline earth metals, technically referred to as Group 2. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra). Radium has two valence electrons and is in Group 2, but is sometimes left off lists of the alkaline earth metals because it is radioactive. - Soccer_Fanatic18
