Question
**Refer to the following figure to answer the questions below.** [Description of Figure: The figure shows atomic mass and atomic number for five distinct elements: Carbon, Oxygen, Hydrogen, Nitrogen, and Phosphorus. These elements and their respective atomic masses and atomic numbers are presented in boxes as follows:] - **Carbon (C):** - Atomic mass: 12 - Atomic number: 6 - **Oxygen (O):** - Atomic mass: 16 - Atomic number: 8 - **Hydrogen (H):** - Atomic mass: 1 - Atomic number: 1 - **Nitrogen (N):** - Atomic mass: 14 - Atomic number: 7 - **Sulfur (S):** - Atomic mass: 32 - Atomic number: 16 - **Phosphorus (P):** - Atomic mass: 31 - Atomic number: 15 **Question:** How many electrons are present in a Phosphorus 3+ atom? A. 34 B. 19 C. 12 D. 16 --- **Explanation:** To determine the number of electrons in a Phosphorus (P) atom with a 3+ charge, we follow these steps: 1. **Determine the number of electrons in a neutral Phosphorus atom:** - Atomic number of Phosphorus (P) is 15, so a neutral Phosphorus atom has 15 electrons. 2. **Calculate the effect of the 3+ charge:** - A 3+ charge indicates the atom has lost 3 electrons. 3. **Final calculation:** - Electrons in neutral Phosphorus atom: 15 - Electrons lost due to 3+ charge: 3 - Electrons in Phosphorus 3+ atom: 15 - 3 = 12 Therefore, there are 12 electrons in a Phosphorus 3+ atom. **Correct Answer: C. 12**
