What do you think are the necessary skills needed by scientists to solve a particular problem?

The skills required to solve problems are known as analytical skills. You use analytical skills when detecting patterns, brainstorming, observing, interpreting data, integrating new information, theorizing, and making decisions based on the multiple factors and options available.

Explanation:

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
