Atomic radius decreases across a row (increasing positive charge in the nucleus causes electrons in the same energy level to "shrink" into the nucleus due to electrostatic attraction). This means that potassium has the largest atomic radius in period 4.
The element with the largest atoms in period 4 is Krypton (Kr). It has the most number of electron shells in that period, resulting in larger atomic size compared to other elements in the same period.
Potassium has the largest atom in period 4 of the Periodic Table of Mendeleev - 243 pm for the calculated atomic radius.
The element with the largest atoms in period 3 would be Actinium.

The element in group 4 period 5 is Zirconium (Zr).
Which element in period 4 has the highest electronegativity?
The element in period 4 with the highest electronegativity is chlorine.
What is the element of life that bonds with 4 chlorine atoms?
The element that bonds with 4 chlorine atoms is carbon. Carbon tetrachloride is a compound where carbon forms bonds with 4 chlorine atoms.
What has the largest ionization energy in period 4?
The element with the largest ionization energy in period 4 is argon. Argon has a full outer electron shell with 8 electrons, making it stable and more difficult to remove an electron compared to other elements in the same period.
How many atoms are in the element copper and in the element carbon and in the element aluminum and how many atoms are in baking soda and how many atoms are in a sugar cube?
There are no "atoms in an element," but rather atoms OF an element. If you are trying to find the number of atoms in a sample of a pure element you divide its weight by its molar mass and then multiply by 6.022 x 10^23 to get the answer in atoms. The answer options are 2,3, or 4.
What element is in period 4 group 2A?
The element in period 4 group 2A is calcium (Ca).
What is an element whose atoms contain 4 electrons in the second energy level?
Carbon is an element whose atoms contain 4 electrons in the second energy level.
What Period 4 element is in the same group as F?
Br (Bromine) is a period 4 element in the same group as F.
What element is group 4 period 5?
The element in group 4 period 5 is Zirconium (Zr).
What metallic element in period 4 has 20 electrons?
Calcium (Ca) is the metallic element in period 4 with 20 electrons.
How many atoms in each element are in 4CaCO3?
In 4CaCO3, there are a total of 4 calcium (Ca) atoms, 4 carbon (C) atoms, and 12 oxygen (O) atoms.
What element is Group 1 period 4?
element K, or potassium
What element is found in group 8 period 4?
