Answer

Explanation:

Step1: Recall atomic - number property

The atomic number is equal to the number of protons in an atom.

Step2: Match atomic numbers with elements

For Si (Silicon), atomic number is 14, so number of protons = 14. For Al (Aluminum), atomic number is 13 (not 16 as given wrongly in the question, but based on correct knowledge), number of protons = 13. For Tc (Technetium), atomic number is 43 (not 18 as given wrongly), number of protons = 43. For Ne (Neon), atomic number is 10 (not 15 as given wrongly), number of protons = 10. For Cu (Copper), atomic number is 29 (not 17 as given wrongly), number of protons = 29. For Fe (Iron), atomic number is 26 (not 19 as given wrongly), number of protons = 26.

Answer:

14, 13, 43, 10, 29, 26
