Alkaline earth metals are found in the second column of the periodic table. they are shiny, silvery-white, and somewhat reactive at normal temperatures and pressure. two of these elements, magnesium and calcium, are essential to all known living organisms. alkaline earth metals lose their two valence electrons to become a +2 ion.

We first find the mass of the object using f=ma
250n= m x 9.8
m = 250/9.8 = 25.51
now multiply this with the acceleration on pluto
f= 25.51 x 0.61
f= 15.56 n
