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 the periodic table from carbon through lead atomic radii...?
Generally increase
Does the old periodic table increase by atomic number?
Yes depending on which scientists version of the periodic table you look at. Henry Moseleys ideas on the periodic table was the first to increase by atomic number.
Where are atoms with the largest and smallest atomic radii found?
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.
Explain the large decrease in atomic radii as you move across a period from group 1 to group 14?
Atomic radius increases down the group due to increase in no.of orbits around the nucleus.
What happens to the atomic size of the atoms as you go from left to right of the periodic table?
The atomic radius decrease from left to right in the periodic table.
How does atomic radii increase or decrease in the table?
atomic radii increases from left to right in the periodic table from metal to non metal in the right
As you move down the periodic table from carbon through lead atomic radii...?
Generally increase
How can you find out the atomic radii?
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.
What are on the periodic table is the greatest in atomic radii?
group 1 elements
Do the elements to the right of the periodic table have small or large radii?
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?
The elements with the smallest atomic radii are found in the top of the P block of the periodic table. Helium (He) has the smallest atomic radius. Francium, on the other side of the periodic table (very bottom of the S block), has the largest atomic radius.
Does the old periodic table increase by atomic number?
Yes depending on which scientists version of the periodic table you look at. Henry Moseleys ideas on the periodic table was the first to increase by atomic number.
How does the atomic radius increase or decrease horizontally on the periodic table?
Atomic radius decreases horizontally in periodic table. This is due to increase in nuclear charge.
Where are atoms with the largest and smallest atomic radii found?
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.
Are there any trends to the periodic table?
Atomic Radii,Ionic Radii, First Ionization Energy,Second and Higher Ionization Energies, Electron Affinity.
How do atomic radii change from left to right across a horizontal row of the periodic table and what is the main reason?
Atomic radii decreases on moving from left to right as the effective nuclear charge increases.
Do protons shrink when moving them left to right the periodic table?
No. Atomic radii shrink. Protons never shrink.
