Explanation:
Electronic configuration: 4d55s2
The electronic configuration of an element tells us about the arrangement of electrons in its atoms. The first number indicates the principal energy level (n) and the letter represents the type of orbital (l). The superscript number gives the number of electrons in that orbital.
Principal Energy Level (n): The highest value of n in the electronic configuration is 4, so the element belongs to the 4th period.
Type of Orbital (l): The d-orbital has a value of l=2. The first digit in the electronic configuration is 4d5 which means there are 5 electrons in the d-orbital.
Number of Electrons: The total number of electrons in the electronic configuration is 29. This means the element has an atomic number of 29.
Group and Period: The element belongs to the 7th group because it has 2 electrons in the outermost s-orbital. The element belongs to the 5th period because it has electrons filling the 4th and 5th energy levels.
Therefore, the correct answer is option 'C' (7th group and 5th period).
