Answer:

- Ion represents a particle that occurs when an atom either loses or gains electrons. Ions can be cations and anions.

-Group 1 elements can be cut with a knife because they're generally very soft metals. Across the period, atom density increases making the element atoms harder. Since group 1 elements show up first in the PSE, they're the softest, and thus, can be cut with a knife.
