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.

is it cause t doesn't say that its either potassium or krypton

Which element in period 4 has the highest electronegativity?
The element in period 4 of the Periodic Table with the highest electronegativity is krypton (2.96). The period 4 element with the lowest electronegativity is potassium (0.82).
What period on the table is scandium?
Scandium is a period 4 element.
What is the element of life that bonds with 4 chlorine atoms?
Carbon.
How many atoms of each element can be found in a unit HC2H3O2?
2 Carbon atoms, 4 Hydrogen atoms, 2 Oxygen atoms
What is the difference between period 4 and 5 on the periodic table?
There are 4 electronic shells in period 4 while there are 5 shells in period 5.Elements of period 4 are smaller in size as compared to elements of period 5.Example of period 4 element is potassium and period 5 element is tin.
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.
Which element in period 4 has the highest electronegativity?
The element in period 4 of the Periodic Table with the highest electronegativity is krypton (2.96). The period 4 element with the lowest electronegativity is potassium (0.82).
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 a metal of group 4 with 28 protons?
There is no element with 28 protons in group 4. I think you are getting confused with group 4 and PERIOD 4. In period 4, the element with 28 protons is Nickel.
What was Daltons theory based on?
Dalton's theory was based on five principle: 1.An element is fundamentally different from any other element. 2.All atoms of a each element are identical. 3. Atoms from one element can combine with atoms from another element to form compounds. 4. Atoms cannot be created or divided 5. Element are made of small particle called atoms.
What period on the table is scandium?
Scandium is a period 4 element.
What is the element of life that bonds with 4 chlorine atoms?
Carbon.
