Question

bell ringer: 1. sodium is in group 1 on the periodic table. which statement best describes the charge of the ion it forms? why? - cation with a +1 charge - anion with a +1 charge - cation with a +2 charge - anion with a -1 charge 2. chlorine is in group 17 on the periodic table. which statement best describes the charge of the ion it forms? why? - cation with a -2 charge - anion with a -2 charge - cation with a +1 charge - anion with a -1 charge

Explanation:

Step1: Analyze sodium's valence electrons

Sodium in Group 1 has 1 valence - electron. It loses this electron to achieve a stable electron configuration.

Step2: Determine the ion type and charge

When an atom loses electrons, it forms a cation. Losing 1 electron gives a + 1 charge. So sodium forms a cation with a + 1 charge.

Step3: Analyze chlorine's valence electrons

Chlorine in Group 17 has 7 valence - electrons. It gains 1 electron to achieve a stable electron configuration.

Step4: Determine the ion type and charge

When an atom gains electrons, it forms an anion. Gaining 1 electron gives a - 1 charge. So chlorine forms an anion with a - 1 charge.

Answer:

1. cation with a +1 charge
2. anion with a -1 charge
