Question

1. sulfur is represented by the following lewis structure. which of these elements has the same lewis structure? a. oxygen b. magnesium c. chlorine d. phosphorus 14. which electron - configuration represents boron, b? a 1s²2s²2p¹ b 1s²2s² c 1s²2s²2p⁶3s¹ d 1s²2s²2p⁶3s²3p⁶4s²3d³ 15. how many valence electrons would an atom of gallium (ga) have? a. 2 b. 3 c. 4 d. 5 16. in the configuration notation 3p⁵, the number 5 represents the - a. energy level. b. number of electrons in the energy level. c. number of electrons in the orbital. d. number of protons in the energy level.

Explanation:

1. Lewis structures depend on valence electrons. Sulfur (group 16) has 6 valence electrons; oxygen (group 16) also has 6.
2. Boron (atomic number 5) has electron configuration \(1s^2 2s^2 2p^1\).
3. Gallium (group 13) has valence electrons equal to its group number, 3.
4. In \(3p^5\), the superscript 5 indicates electrons in the \(p\) orbital.

Answer:

1. a. Oxygen
2. A. \(1s^2 2s^2 2p^1\)
3. b. 3
4. c. number of electrons in the orbital.
