the atomic radius decreses from left to right in Periodic Table due to increase in the number of succesive element the electrons of the outermost shell are more attracted towards nucleus and the atomic radius or atomic size decreases.
Generally the atomic radius decrease from the left to the right of the periodic table in each period; and the atomic radius increase in a group down the column.
Some exceptions exist.
in general it decreases
Atomic radius usually decreases from left to right across a period of the periodic table.
In the periodic table, the atomic size increases with every period due to addition of an extra shell. The atomic size decreases with every group since no. of electrons and protons are increased with every group across a period leading to extra electrostatic force of attraction between electrons and the nucleus and thus shrinking the size of the atom.
Name: Bromine Symbol: Br Atomic number: 35 Atomic weight: 79.904 (1) Standard state: liquid at 298 K Group in periodic table: 17 Group name: Halogen Period in periodic table: 4 Block in periodic table: p-block Colour: red-brown, metallic lustre when solid Classification: Non-metallic
Bromine has a SMALLER atomic radius because it has one more electron shell than Iodine. On the periodic table, atomic radius of an atom decreases across a period and increases down a group. Since Bromine and Iodine are in the same group, you know Bromine has a smaller atomic radius because it is in a lower period.
Elements atomic radii increase in size as they run down the columns of the periodic table or across the periodic table from right to left. So, Al is larger than Cl. XP
As you move across the periodic table from left to right (across a period), the atomic radius of the elements tends to decrease.
Atomic radius usually decreases from left to right across a period of the periodic table.
The atomic radius decrease, with several exceptions in periods 6 and 5.
1. In a period is a trend of decrease from left to right but it is not absolute.2. In a group the atomic radius increase moving down.

from left to right the atomic radius decreases as the electrons that get added are added in the same shell as they are in the same period. the shielding effect remains constant but the proton number increases which inturn increases the effective nuclear pull on the electrons bringing the electrons closer to the nuclei hence decreasing the radius of the atom
Atomic size decreases across a period
the atomic number.
The atomic number increases
Yes. Generally atomic radii turn to decrease as you move across the periodic table from left to right. this is because the nuclear charge increases as you move right across the period but the electron screening remains the same. consequently, the protons in the nucleus has a greater pull on the electrons.
These are the patterns of the periodic table across the period. 1. The atomic radius reduces as we move across a period from left to right, 2. The ionization energy increases as we move across a period. 3. The electron affinity decreases as we move across a period. Learning them enables us to have a clear view of elements in the periodic table.
