Final answer:
To draw the Lewis structure for N + Ba, place the atoms in the structure, connect them with a single bond, and distribute the remaining electrons to fulfill the octet rule. Nitrogen will have a positive charge and form a single bond with Barium.
Step-by-step explanation:
The Lewis structure for the compound N + Ba can be determined by first determining the number of valence electrons for each atom. Nitrogen (N) has 5 valence electrons and Barium (Ba) has 2 valence electrons. The Lewis structure is then constructed by placing the atoms in the structure, connecting them with a single bond, and distributing the remaining electrons around the atoms to fulfill the octet rule. In this case, nitrogen will have a positive charge (+) and will form a single bond with Barium, represented by the Lewis structure: N^+ - Ba.
