Answer
The metallic elements in the periodic table among A, B, C, D, and E are identified as follows:
Element A: Metallic
Element B: Metallic
Element C: Metallic
Thus, the letters representing metallic elements are A, B, and C.

Answer
The elements with the most similar chemical properties are A and B. This is typically determined by their position in the periodic table, indicating they are likely to share similar valence electron configurations.
Step 3
b) State how many more protons there are in an atom of element B than in an atom of element A.
