If the atomic number of an element is 60, it will be placed in the periodic table in the 4th group, 7th period 4th group, 6th period 3rd group, 7th period 3rd group, 6th period

The atomic number of an element determines its position in the periodic table. The atomic number is equal to the number of protons in an atom's nucleus.

Step 1: Identify the atomic number. In this case, the atomic number is 60.

Step 2: Use the periodic table to find the element with this atomic number. The element with atomic number 60 is Neodymium (Nd).

Step 3: Determine the group and period of this element. Neodymium (Nd) is in the 6th period and the 3rd group of the periodic table.

So, the correct answer is 3rd group, 6th period.
