(a) Write out the ground-state electron configuration $\left(1 s^{2} 2 s^{2},\right.$ and so on for the beryllium atom. (b) What element of next-larger $Z$ has chemical properties similar to those of beryllium? (See Example
29.3.) Give the ground-state electron configuration of this element. (c) Use the procedure of part (b) to predict what element of nextlarger $Z$ than in (b) will have chemical properties similar to those of the element you found in part (b), and give its ground-state electron configuration.
