What element has the same number of valence electrons as argon

The answer is not sulfur . Give the name and charge of one ion that has the same electron configuration as Argon (Ar). Oxygen (O) has the same number of valence electrons as sulfur. An ion can be an element that gained or lost an electron.

There are two elements actually and those elements are Carbon and Silicon

Explanation:Plz mark brainliest if im right

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.

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
