Which atom gives up its electrons most easily?

THE ANSWER IS “Rb”

In particular, cesium (Cs) can give up its valence electron more easily than can lithium (Li). The easy of giving up an electron varies as follows: Cs > Rb > K > Na > Li with Cs the most likely, and Li the least likely, to lose an electron. In fact, for the alkali metals (the elements in Group 1). I hope I helped you.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

i believe that it is a exoplanet
