Please help asap! For an important test. Giving brainliest to correct. The diagram shows the electron configuration of an atom of an element for the electrons in the s and p orbitals.

What is the group number of the element in the periodic table?

Select one:

a. 17
b. 16
c. 2
d. 1

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.
