Question

question 17 of 25
which electrons in an atom have the highest energy?

a. the s orbital electrons

b. the core electrons

c. the valence electrons

d. the p orbital electrons

Explanation:

Valence electrons are the outermost electrons of an atom. Electrons in an atom are arranged in energy levels (shells), and the outermost electrons (valence electrons) are farther from the nucleus compared to core electrons. Electrons farther from the nucleus have higher energy because they are less strongly attracted by the nucleus. S - orbital and p - orbital electrons can be either core or valence electrons, so their energy depends on their position (core or valence). Core electrons are closer to the nucleus and have lower energy. So valence electrons have the highest energy among the given options.

Answer:

C. The valence electrons
