What element in row 6 of the periodic table has the largest atomic radius?
Cesium (Cs), atomic number 55, has the largest atomic radius in period 6.Only francium (row 7) may be larger, but testing is difficult because francium does not exist in any meaningful amounts (maybe 30 g on the entire Earth).
How does the atomic radius change from top to bottom in a group 1 and 2 in the periodic table?
Going down and to the left on the periodic table, atomic radius increases. Therefore, the smallest atomic radius is that of Helium (He), and the largest is that of Francium (Fr). Coincidentally, these are also the most and least reactive elements.
Who has the largest radius calcium atom or calcium ion?
The radius of a cadmium atom is smaller than the radium of a mercury atom. The trend for atomic radius is that the radius becomes larger toward the left side of the row and toward the bottom of the group.
Largest element in a row and largest element in a column?
The largest element in a Period (row) will be on the right of that Period (i.e. an inert gas). The largest element in a Group (column) will be at the bottom of that group. Examples; Helium is larger than Hydrogen (Period 1) Krypton is larger than Potassium (Period 3) Francium is larger than Lithium (Group 1) Ununquadium is larger than Carbon (Group 3)
Where can you find a graph of atomic radius vs atomic number?
See the Web Links to the left for the answer.The AntoineFrosturg.edu page has a graph of atomic radius versus atomic number.The HMCO.com page has an interactive feature where you can individually plot the atomic radius for each row or column of the periodic table.The other two sites have tables with the actual numbers for the atomic radii. Go to wikipedia.org and look up atomic radius, they have 2 charts for it.
What element in row 6 of the periodic table has the largest atomic radius?
Cesium (Cs), atomic number 55, has the largest atomic radius in period 6.Only francium (row 7) may be larger, but testing is difficult because francium does not exist in any meaningful amounts (maybe 30 g on the entire Earth).
Which element in row 6 of the peroidic table has the largest radius?
Cesium
What element has the largest atoms period 4?
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.
Given any two elements within a group is the element with the larger atomic number likely to have a larger or smaller atomic radius than the other element?
The atomic radius decreases across a period from left to right and increases down in a given group. That means that since the lower the element is in a group, the larger the atomic radius will be. The atoms with the largest atomic radii are located in Group I and are at the bottom of groups.
Which element is the largest K Rb Na Li?
Rb (rubidium) is the largest element among K (potassium), Rb (rubidium), Na (sodium), and Li (lithium). This is because as you move down a group in the periodic table, the atomic size increases due to the addition of more electron shells.
What effect does an additional proton have on atomic size?
An additional proton, in the same period (row) makes the radius smaller and the nucleus bigger. It also changes the element.
What happens to the atomic radius as the atomic number increases?
Going across a row in the peiodic table, the atoms have more protons and electrons causing a stronger attractive force, pulling the electrons closer to the nucleus, making the atomic radius decrease. As a new shell is added ( next row down) the atomic radius increases
What is the most massive atom on the periodic table?
Atoms size get smaller as you go across from left to the right in periods and gets larger down the group on the periodic table. For a given group, the largest atom is in period 7. For a given period, the largest atom is in group 1.
What do notice on the atomic number of elements in a row as one goes to the right of the table?
The atomic number increases from left to right across a period (row). This is because the atomic number is the number of protons in the nuclei of the atoms of each element. No two elements have the same atomic number. It is the protons that define an element.
How does the atomic radius change from top to bottom in a group 1 and 2 in the periodic table?
Going down and to the left on the periodic table, atomic radius increases. Therefore, the smallest atomic radius is that of Helium (He), and the largest is that of Francium (Fr). Coincidentally, these are also the most and least reactive elements.
