From what I understand, the guy who came up with the periodic table just used trial and error to find a way to chart the elements, the way he arranged them is as close as it gets to fitting a pattern.
As you move down a group in the Periodic Table, the number of energy levels (shells) increases, leading to an increase in atomic size. Electrons are added to these energy levels, increasing the distance between the nucleus and the outermost electrons, resulting in larger atomic radii.
a. shielding of inner electrons
b. valence electrons in larger orbitals
c. increased charge in the nucleus
Down a group, the number of shells (or energy levels) increases. So the atomic size (or radius) increases.
increases
increase gradually due to the addition of more electron shells and increased nuclear charge.
The atoms with the largest atomic radii are found in the lower right side of the periodic table. Smallest atoms are found in the higher left part of the periodic table. He has the smallest atomic radii.
I'm unable to graph atomic radii in this text-based format. However, you can find data on atomic radii for the first 20 elements in a periodic table resource or chemistry textbook. Atomic radii generally decrease across a period from left to right and increase down a group from top to bottom.
Atomic radii generally increase going down the periodic table because the number of electron shells increases, leading to a larger atomic size. Additionally, the increasing nuclear charge is offset by increased electron shielding in larger atoms, allowing the outermost electrons to be further from the nucleus, making the atom larger.
Yes, the old periodic table is arranged in order of increasing atomic number. Each element's position on the table is based on its number of protons in the nucleus.
atomic radii increases from left to right in the periodic table from metal to non metal in the right
Look for a reference chart in a book or online. Look for a Periodic Table of the Elements that has the atomic radii on it.
The radii of elements generally decrease as you move from left to right across a period in the periodic table. The radii then increase as you move down a group in the periodic table. This trend is due to changes in the atomic structure of the elements.
group 1 elements
Across a period the atomic size decreases. Hence elements in the right side of the periodic table have small size / radii.
The elements with the smallest atomic radii are found in the top right corner of the periodic table, specifically in the noble gases group. These elements have a stable configuration and therefore have a very compact atomic structure.
increase gradually due to the addition of more electron shells and increased nuclear charge.
Atomic radius decreases horizontally in periodic table. This is due to increase in nuclear charge.
The atoms with the largest atomic radii are found in the lower right side of the periodic table. Smallest atoms are found in the higher left part of the periodic table. He has the smallest atomic radii.

Atomic radii decreases on moving from left to right as the effective nuclear charge increases.
