What is an electron dot diagram?

An electron dot diagram is a diagram used to represent the valence electrons of an atom in a simple way. Valence electrons are the electrons in the outermost shell of an atom, which are involved in chemical bonding.

In an electron dot diagram, the symbol of the element is used to represent the nucleus and inner electrons of the atom, and dots are placed around the symbol to represent the valence electrons. Each dot represents one valence electron, and the dots are placed on each of the four sides of the symbol (top, bottom, left, and right) before doubling up.

Thus, the Arsenic (As) element's symbol could replace the question mark in the diagram. Therefore, option D is correct.
