Question

Compare the models of a chlorine atom versus a chlorine ion. How are the two different? CHOOSE ALL THAT APPLY.

A. The atom is neutral; the ion has a -1 charge.
B. The ion has eight outer electrons; the atom does not.
C. The ion has a larger atomic mass number that the atom.
D. The ion has an atomic number the sone greater than the atom.
E. The atom has gained an electron; the ion has lost an electron.

Answer 1

The models of a chlorine atom and chloride ion are different in the following ways:

A. The atom is neutral; the ion has a -1 charge.

B. The ion has eight outer electrons; the atom does not.

Step-by-step explanation:

To compare the models of a chlorine atom versus a chlorine ion, we can start by noting several key differences. The correct answers to the student's question are:

• A. The atom is neutral; the ion has a -1 charge. A chlorine atom is neutral with 17 protons and 17 electrons, while a chlorine ion, or chloride, has gained an electron, thus having 18 electrons and carrying a -1 charge.
• B. The ion has eight outer electrons; the atom does not. After gaining an electron, the chloride ion has a complete octet in its valence shell, fulfilling the octet rule for maximum stability.

Electron transfer is the movement of electrons from one atom to another, and it is a key concept in understanding how atoms become ions. In the case of chlorine, it tends to gain an electron to achieve an energetically stable configuration. The result is the formation of an ionic bond between, for example, sodium ions and chloride ions, creating compounds like sodium chloride (NaCl).

Answer 2

A. The atom is neutral; the ion has a -1 charge.

Step-by-step explanation:

• Atoms are often neutral. When they gain or lose a charge they become an ion.
• Cation is a positively (+) charged species
• Anion is a negatively( -) charged species

Cl will accept an electron resulting in its negitive charge
