Therefore, rubidium has the largest atomic radius whereas helium has the smallest. Trends in the atomic radius showing that moving down the periodic table, size increases, whereas moving across the periodic table from left to right, size decreases.
Which atoms has the largest atomic radius?
Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.
Which of the following has the largest radius?
Thus O2− has a minimum z-effective thus largest radius.
Which of the following elements has the greatest atomic radius *?
Answer: The answer to your question is: Al, Si have the greatest and S, C have the smallest. Explanation: Atomic radius increases from right to left in the periodic table.
Which of the following elements has the largest atomic size?
Barium (Ba) will have the largest atomic size.
What has the smallest atomic radius?
Explanation: Helium has the smallest atomic radius. This is due to trends in the periodic table, and the effective nuclear charge that holds the valence electrons close to the nucleus.
How do you find atomic radius?
Atomic radius is determined as the distance between the nuclei of two identical atoms bonded together. The atomic radius of atoms generally decreases from left to right across a period. The atomic radius of atoms generally increases from top to bottom within a group.
Which of the following has smallest radius?
Hence, Cl has the smallest radius.
What is the atomic radius of Br?
185 pm
What is the atomic radius of Al?
184 pm
Which element has the smallest atomic radius quizlet?
Therefore, rubidium has the largest atomic radius whereas helium has the smallest.
Which of the following halogens has the largest atomic radius?
