Answer

Brief Explanations:

For Question 6, a Lewis electron - dot symbol represents the valence electrons in the ground - state of an atom. It is a way to visualize the electrons available for bonding. For Question 7, a copper(II) ion ($Cu^{2 + }$) is formed when a copper atom loses two electrons. A positive ion is formed by electron loss, and the Roman numeral II indicates a + 2 charge.

Answer:

Question 6: all the valence electrons in the ground - state of an atom. Question 7: loses two electrons.
