Question
What is the electronic structure of sodium (Na) and how does it relate to its position in the periodic table?
Answer
The electronic structure of sodium (Na) is 2, 8, 1. This structure indicates that sodium has one electron in its outer shell, which is why it is in Group 1 of the periodic table, as elements in this group have similar outer electron configurations.
Explanation
This answer is strong because it connects the electronic structure of sodium to its group placement in the periodic table, demonstrating understanding of how electron arrangement influences chemical properties. The question tests the student's ability to link electronic structure with periodic trends.
Common mistake
Misrepresenting Electron Shells
Students often incorrectly draw the electron shell diagrams for elements, placing too many electrons in the outer shell or not following the 2,8,8 rule for higher energy levels.
Ensure that the first shell holds a maximum of 2 electrons, the second shell holds up to 8, and the third shell also holds up to 8 for the first 20 elements.
