I believe the answer is copper.... you can always ask for the atomic number or search a chart (images) on Google. :-)
Potassium has a bigger atomic size than copper. This is because as you move down a group in the Periodic Table, the atomic size generally increases due to the addition of more electron shells. Potassium, being below copper in the periodic table, has a larger atomic size.
Potassium is the most reactive, followed by caesium, and then calcium. This is because reactivity generally increases moving down Group 1 of the periodic table due to decreasing ionization energy and increasing atomic size.
Ca (Calcium) has a greater atomic radius than K (Potassium). This is because as we move down a group in the periodic table, the atomic radius increases due to the addition of more electron shells. Calcium is one period below Potassium in the periodic table, leading to a larger atomic radius.
The second ionization energy of calcium is greater than that of potassium. This is because calcium, with its higher nuclear charge and smaller atomic size compared to potassium, holds onto its electrons more tightly.
As you go down a column on the periodic table, the atomic size increases. This is because each subsequent element in the column has an additional energy level of electrons, leading to increased distance between the nucleus and the outermost electrons, resulting in larger atomic size.
because of its smaller size and high charge density.....
No, gallium is smaller than potassium. In the periodic table, the atomic radius of gallium is less than that of potassium, indicating that gallium's atoms are smaller in size.
The atomic radius of iodine is larger than the atomic radius of potassium. This is because as you move down a group in the periodic table, atomic size increases due to the addition of more electron shells. Iodine is located below potassium in the periodic table, hence it has a larger atomic radius.
Potassium is larger than magnesium because potassium has one more electron shell than magnesium, leading to a larger atomic size. Additionally, the increase in nuclear charge from magnesium to potassium is not enough to offset the added electron shell, resulting in a larger atomic radius for potassium.
Bromine, Copper, Calcium, PotassiumBromine- smallest, 4th period atomic #35Copper- second smallest, 4th period, atomic # 29Calcium- second largest, 4th period, atomic # 20Potassium- largest, 4th period, atomic # 19
The atomic radius of potassium is larger than that of sodium. This is due to the increase in atomic size as you move down a group in the periodic table, with potassium being located below sodium.
The atomic size of potassium is approximately 231 picometers (pm). It is a relatively large atom due to having 19 protons and electrons, which results in a larger atomic radius compared to many other elements.
The atom of element 19 (potassium) is larger in size than the atom of element 35 (bromine) because atomic size generally increases as you move down a group in the periodic table. Potassium is in a lower period and has more electron shells than bromine, which contributes to its larger atomic size.
This may vary by your 'definition' of 'bigger'Atom radius Cu: 128 pM, Ni: 124 pM orVanderWaals radius Cu: 140 pM, Ni: 163 pM
From the given elements, potassium has the largest atomic radius.
Down a group, atomic size increases. So Mt is bigger than Co.
Rubidium is softer than potassium. This is because rubidium has larger atomic size and higher reactivity, which makes it more easily deformable when compared to potassium.
Potassium has a larger atomic radius than sodium. This is because as you move down a group in the periodic table, atomic size generally increases due to additional electron shells being added, leading to increased electron-electron repulsion and a larger atomic radius.
