Rank the following elements in Atomic Size from smallest to largest: Fluorine, Molybdenum, & Palladium.
The atomic size of an element usually increases as you move down a group in the periodic table and decreases as you move across a period.
In this case, Fluorine is a small atom and is on the far right of the periodic table, so it will have the smallest atomic size.
Molybdenum is significantly larger than Fluorine and is in the middle of the periodic table, so it will have a larger atomic size.
Palladium is even larger than Molybdenum and is closer to the left side of the periodic table, so it will have the largest atomic size.
Therefore, the ranking from smallest to largest atomic size is:
1. Fluorine
2. Molybdenum
3. Palladium
