Question

18 question (3 points) predict and write the charges and symbols (e.g., ca²⁺) of the monatomic ions formed by the following atoms. 1st attempt part 1 (1 point) sulfur readily forms the following monatomic ion: see periodic table see hint part 2 (1 point) phosphorus readily forms the following monatomic ion:

Explanation:

Step1: Determine sulfur's valence electrons

Sulfur is in group 16, has 6 valence electrons. It gains 2 electrons to achieve a stable octet.

Step2: Write the ion symbol

When sulfur gains 2 electrons, it forms an anion with a - 2 charge. The symbol is $S^{2 - }$.

Step3: Determine phosphorus's valence electrons

Phosphorus is in group 15, has 5 valence electrons. It gains 3 electrons to achieve a stable octet.

Step4: Write the ion symbol

When phosphorus gains 3 electrons, it forms an anion with a - 3 charge. The symbol is $P^{3 - }$.

Answer:

Part 1: $S^{2 - }$
Part 2: $P^{3 - }$
