Explanation: Edg 2020

Ionic compounds are compounds made up of ions. These ions are atoms that gain or lose electrons, giving them a net positive or negative charge. Metals tend to lose electrons, so they become cations and have a net positive charge. Nonmetals tend to gain electrons, forming anions that have a net negative charge.

When things are discussed or described in a spacial manner, they are described in a particular order because it makes more sense to move descriptively by grouping things by a common element and discussing those first.  for instance, in the description of the x-jt7, by comparing the car to a rocket, the writer first describes the outside of the car and concludes by mentioning the inside (or "cockpit").  thus, the spacial organization the writer uses is from the outside to the inside.
