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.
Atomic radii decreases from left to right in the periodic table
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.
Helium has the smallest atomic radius among all the elements on the periodic table. This is because helium has a small number of electron shells and a strong nuclear attraction, which results in a compact atomic structure.
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.
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 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.
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.
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.

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.
Atomic radii decreases on moving from left to right as the effective nuclear charge increases.
No. Atomic radii shrink. Protons never shrink.
Many properties change as you move from left to right on the periodic table. For example: atomic number increases; electronegativity increases; atomic radii decrease etc. etc.
The more energy levels that are occupied by electrons, the larger the atomic radius.
The atomic radius of helium is about 31 picometers. Helium has one of the smallest atomic radii among all the elements in the periodic table due to its small size and high nuclear charge.
