Which atom in the ground state has five electrons in its outer level and ten electrons in its kernel?.

Arsenic is in group 15, so its atoms have 5 valence electrons. We can also determine the number of valence electrons of the representative elements by determining their ground state electron configurations. The highest energy (outermost) s and p sublevels, also called the valence shell, contain the valence electrons.
