How does the reactivity of an alkaline earth metal compare with that of an alkali metal in the same period?

Answer 1

Group 2 metals are less reactive than Group 1 metals in the same period because their ionisation energies are higher - it is more difficult for them to lose electrons.

Answer 2

Reactivity Of Alkaline Earth Metals

Answer 3

The alkali metals are the 1st actual column, Lithium (Li), Sodium (Na), Potassium (ok),Rubidium (Rb) Caesium (Cs) and Francium (Fr). all of them have single electrons of their outer shells and are very reactive. they're spoke of as alkali metals because of the fact they are going to all settle for electrons to fill the 1st orbital of the outer shell. The alkali earth metals are the subsequent column, Berrylium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba) and Radium (Ra). all of them have 2 electrons of their outer shell, an entire first orbital. this means that they are much less reactive tha the alkali metals. The Halogens are the penultimate column, Flourine (F), Chlorine (Cl), Bromine (Br), Iodine (I) and Astatine (At). all of them have 7 electrons of their outer shell. ultimately, the noble gases are the final column, Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe) and Radon (Rn). All have finished outer shells, of 8 electrons (aside from Helium which has 2) and as such they're very unreactive, which provides them an option call of the inert gases.

Answer 4

the radius of the atom is smaller
the reactivity is less than
