How many significant digits are in the number 1.0 × 10^3?

the most likely explanation for the increase in average beak size of the medium ground finch is that the

Answer:

Well according to the Law of Evolution, depending on where the Finch lives and what it eats depends on it's beak size. For example, if a Finch lives on the coast and eats small fruits it will have a short and stubby beak to peck at the fruits, but if the Finch ate crabs it's beak would be long to swoop down and pluck up crabs.

Hope this helps!

Which pair of elements have the same valence electronic configuration of np³?

Dennis_Churaev [7]

Answer:

(c) P and Sb

Explanation:

We can determine the number of valence electrons of an element:

If it belongs to Groups 1 and 2, the number of valence electrons is equal to the number of group and the differential electron occupies the s subshell.

If it belongs to the groups 13-18, the number of valence electrons is equal to: "Number of group - 10" and the differential electron occupies the p subshell.

Which pair of elements have the same valence electronic configuration of np³?

(a) O and Se. NO. They belong to the group 16 and the valence electron configuration is ns² np⁴.

(b) Ge and Pb. NO. They belong to the group 14 and the valence electron configuration is ns² np².

(c) P and Sb. YES. They belong to the group 15 and the valence electron configuration is ns² np³.

(d) K and Mg. NO. They belong to the groups 1 and 2 and the valence electron configuration is ns¹ and ns².

(e) Al and Ga. NO. They belong to the group 13 and the valence electron configuration is ns² np¹.
