`""_(6)^(12C` and `""_(6)^(14)C` are two elements. Do both these elements get different positions in modern periodic table? Explain your answer. Identify the period and group to which they belong in the modern periodic table with suitable reason.

Explanation

No, `""_(6)^(12)C` and `""_(6)^(14)C` will be placed in same slot (position). The modern periodic table is based on atomic number, not on atomic mass. Since, both C-12 and C - 14 have some atomic number, hence they are placed in same slot.
