The smallest atomic radius in period 5 belongs to the element with the highest nuclear charge, which is iodine (I) from Group 17. This is because as you move across a period, the nuclear charge increases, leading to stronger attraction for the electrons and a smaller atomic radius.
Ruthenium (Ru) has the smallest atomic radius in period 5 - 130 pm.

Rank these elements in terms of increasing atomic radius?
In terms of atomic radius, the sequence would be oxygen, carbon (both period 2), magnesium (period 3), rubidium (period 4), and cesium (period 5). Note that order by periods is not absolute: in each period, the elements toward the far left side have the largest radii. For example, the radius for lithium in period 2 is larger than almost all of the elements in periods 3 and 4. *Numerically, the elements O, C, Mg, Rb, and Cs have respective radii of about 60, 70, 150, 235, and 260 picometers.
What atom has the largest size in period 5?
Rubidium has the largest atomic size in period 5 of the periodic table.
What property increases going down the periodic table?
The atomic radius increases going down the periodic table due to the addition of more electron shells around the nucleus, leading to increased shielding effect and weaker attraction between the electrons and the nucleus.
What is the distance from the center of the nucleus of an atom to its outermost electron?
The distance from the center of the nucleus of an atom to its outermost electron is known as the atomic radius. This distance can vary depending on the specific element and its electronic structure. Atomic radius generally increases as you move down a group on the periodic table and decreases as you move across a period from left to right.
What happens to the atomic radius within a group of elements?
The atomic radius generally increases going down a group of elements. This occurs because each subsequent element has an additional electron shell, leading to an increase in size. This trend is primarily due to the increase in the number of electron shells and the shielding effect of inner electrons.
What happens to the atomic radius when you go from left to right on the periodic table of elements?
The atomic radius decrease, with several exceptions in periods 6 and 5.

What is the size of cobalt the atom?
The atomic radius of cobalt is about 135 pm (±5 pm).
What period is strontium in?
Strontium is in the 5th period of the periodic table.

Period 5 in the periodic table?
Period 5 in the periodic table includes elements from 37 (Rb) to 55 (Cs). This period consists of transition metals, lanthanides, and actinides, as well as nonmetals and metalloids like iodine and tellurium. Elements in period 5 generally have increasing atomic numbers and atomic masses from left to right.
What is the size of a cobalt atom?
The atomic radius of a cobalt atom is about 135 picometers (pm) or 1.35 angstroms (Å).
What is the highest atomic number in period 5?
We can find Polonium as a non metal element. Atomic number of it is 84.
