Explanation:
Grouping of Elements
- Elements in the periodic table are arranged in groups based on similar chemical properties.
- Elements in the same group have the same number of valence electrons.
Atomic Numbers of Given Elements
- Element A (atomic number 9) is Fluorine (F).
- Element B (atomic number 11) is Sodium (Na).
- Element C (atomic number 17) is Chlorine (Cl).
- Element D (atomic number 12) is Magnesium (Mg).
- Element E (atomic number 13) is Aluminum (Al).
Grouping of Elements
- Elements A and C belong to the same group because they both belong to Group 17 (also known as Group VIIA), which is the Halogens group.
- Fluorine (F) and Chlorine (Cl) are both halogens and have 7 valence electrons.
Therefore, the correct pair of elements that belong to the same group is option C - A and C.
