Which best explains the observed trend in atom radii going down the periodic table?
As you move down the Periodic Table, atomic radii increase primarily due to the addition of electron shells. Each successive element in a group has an additional energy level of electrons, which increases the distance between the nucleus and the outermost electrons. Additionally, while nuclear charge increases, the effect of increased shielding from inner-shell electrons reduces the effective nuclear charge felt by the outermost electrons, allowing them to occupy a larger volume.

Which best explains that observed trend in atomic radii going down the periodic table?
Atomic radii increase down a group in the periodic table primarily due to the addition of electron shells. As new electron shells are added, the distance between the nucleus and the outermost electrons increases, resulting in a larger atomic size. Furthermore, the increased shielding effect from the inner electron shells reduces the effective nuclear charge felt by the outer electrons, allowing them to spread out further from the nucleus. This combination of added shells and shielding leads to the observed trend of increasing 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.
What are on the periodic table is the greatest in atomic radii?
group 1 elements
How can you use the periodic table and electron configurations to predict relative atomic radii and ionization energies for two atoms?
in a periodic table1>from left to right across a periodic tableionization energy increases & atomic radii decreases2>from top to bottom along a groupionization energy decreases and atomic radii increaseswhen considering the periodic table from left to right the main energy level is the same,but the number of electrons and protons increases.so the nuclear attraction increases and thus the electrons are pulled closer towards the nucleus.this decreases the atomic radii and increases the amount of energy needed to remove the electron in the outer most shell from the strong attraction.that is the ionization energy increases and atomic radii decreases when going from left to right across the periodwhen going down the group in a periodic table the electronic configuration of elements increases by 1 shell.that is the number of main energy levels increases.so the nuclear attraction between the atomic nuclei and the last electron decreases due to the increase in the distance.therefore it is more easier to remove the electron in the outer most shell of an element than that of the element immediately above it.therefore the ionization energy increases down the group.and since number of energy levels increases the atomic radius increases.
Which characteristics both generally decrease in period three from left to right?
Atomic radii decreases from left to right in the periodic table
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.

What best explains the observed trend in atomic radii going down periodic table?
The more energy levels that are occupied by electrons, the larger the atomic radius.
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.

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.
What are on the periodic table is the greatest in atomic radii?
group 1 elements
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.
Are there any trends to the periodic table?
Atomic Radii,Ionic Radii, First Ionization Energy,Second and Higher Ionization Energies, Electron Affinity.
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.
Why do atomic radii generally get larger going down the periodic table?
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.
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.
