Question

which particle represents a model of a chloride ion in comparison to the original chlorine atom?
chlorine atom
particle a
particle b
particle c
enter the answer choice letter.

Explanation:

A chlorine atom gains one electron to form a chloride ion. Adding an electron increases the electron-electron repulsion, causing the electron cloud to expand, making the chloride ion larger than the original chlorine atom. Among the particles, Particle B is the largest, matching this change.

Answer:

B
