A student wants to do scientific research on how nuclear fusion can be used
as a power source on Earth. What type of scientist does the student want to
become?
O A. A biologist
O B. A chemist
C. An astronomer
O D. A physicist

n has four pairs of electrons in the valence shell, electrons repel one another ,n has 7 protons in its nucleus, and since n has 7 protons, it must fill the second shell, giving it 4 pairs of electrons. the electrons form 3 bonds and 1 lone pair of electrons. each pair of electrons repels the other pairs, so they are equally far apart.

so all of the above

your answer would be “dry”

the answer to this question is 3.
