As you move across a row on the Periodic Table, the atomic radii becomes smaller due to the attraction between positive protons and negative electrons. As you move down a column, the radii increase due to the addition of valance electrons.

Atomic radii generally decrease across a period from left to right due to increased effective nuclear charge pulling electrons closer to the nucleus. Within a group, atomic radii increase going down the group as additional energy levels are added, leading to increased electron shielding and less pull from the nucleus.

∙ 11y agoFrom left to right across a period, atomic radius goes down (even though atomic number goes up.) From top to bottom down a group, atomic radius goes up (because you're adding a principal energy level.) This trend, along with most of the others, has to do with the amount of attraction between the positively charged nucleus and the negatively charged electron cloud.

∙ 11y agoIn the periodic table of elements, atomic radius decreases slowly as you go from left to right in a period, and it increases rapidly as you go from top to bottom in a group.

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?
Elements to the right of the periodic table have smaller radii due to increased effective nuclear charge, which attracts the electrons closer to the nucleus. This results in a greater pull on the outer electrons and smaller atomic radii overall.
Are the atomic radii of Mn and Fe same?
No, the atomic radii of Mn (manganese) and Fe (iron) are not the same. Typically, atomic radii decrease across a period (from left to right on the periodic table), so Fe would have a smaller atomic radius compared to Mn.
Which characteristics both generally decrease in period three from left to right?
Atomic radii decreases from left to right in the periodic table
What is the atomic radius of selenium if germanium's is 122 pm and arsenic's is 120 pm?
The atomic radius of selenium can be estimated to be approximately between 116 pm and 118 pm based on the trends in atomic radii going down a group in the periodic table. This is because atomic radius generally increases as you move down a group, so selenium's atomic radius would be smaller than arsenic's and germanium's.
Are there any trends to the periodic table?
Atomic Radii,Ionic Radii, First Ionization Energy,Second and Higher Ionization Energies, Electron Affinity.
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
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.
Do the elements to the right of the periodic table have small or large radii?
Elements to the right of the periodic table have smaller radii due to increased effective nuclear charge, which attracts the electrons closer to the nucleus. This results in a greater pull on the outer electrons and smaller atomic radii overall.
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.
The elements with the smallest atomic radii are found in the?
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.
How are period and group trends in atomic radii are related to electron configuration?
Period trends in atomic radii show a decrease across a period due to increasing nuclear charge and more protons pulling electrons closer. Group trends in atomic radii show an increase down a group due to additional energy levels being added, leading to larger atomic size. Electron configuration influences these trends by determining the number of energy levels and electron shielding in an atom, affecting the distance of the outer electrons from the nucleus.
Graph the atomic radii for the first 20 elements?
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.
What happens to the radii of the elements between 2 highest peaks?
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.
What explains the observed trend in the atomic radii going down the periodic table?
The more energy levels that are occupied by electrons, the larger the atomic radius.
Do protons shrink when moving them left to right the periodic table?
No. Atomic radii shrink. Protons never shrink.
