What else can I help you with?
Put the metals caesium calcium and potassium in order of reactivity most reactive first?
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.
Which has the greatest atomic radius K or Ca?
Both atoms have the same van der Waal's radius (2.00) Radii that are not available in either of these publications have RvdW 2.00 A. However, Caesium has a greater covalent radius (1.67) as compared to that of Radon (1.50) See the link for more info.
Which is greater the second ionization energy of potassium or that of calcium?
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.
When you go down a column on the periodic table how does the atomic size go?
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.
Why lithium is harder than sodium and potassium?
because of its smaller size and high charge density.....
Is gallium bigger than potassium?
if i remember correctly, the element which has the biggest atomic number is the biggest.
Which is bigger the atomic radius of potassium or atomic radius of iodine?
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.
Why is potassium bigger then magnesium?
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 potassium copper and calcium in increasing size would be ordered like what?
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
How does its potassium atomic radius compare to that of sodium?
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.
WHAT is the atomic size of potassium?
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.
How do the atoms of elements 19 and 35 compare in size?
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.
Which atom is bigger copper or nickel?
This may vary by your 'definition' of 'bigger'Atom radius Cu: 128 pM, Ni: 124 pM orVanderWaals radius Cu: 140 pM, Ni: 163 pM
What neutral atoms has the largest atomic size betwee K Al S and Si?
From the given elements, potassium has the largest atomic radius.
Which atom is bigger Co or Mt?
Down a group, atomic size increases. So Mt is bigger than Co.
Is rubidium harder or softer than potassium why?
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.
What has a larger atomic radius sodium or 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.
