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.

How does the atomic raduis change across a period of the periodic table?
Atomic radius usually decreases from left to right across a period of the periodic table.
What pattern in atomic size occurs in 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.
What period does bromine belong to?
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
Why has bromine got a bigger atomic radius than iodine?
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.
Which is bigger in size aluminum atom or chlorine atom?
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
WHAT BEST STATES THE TREND IN ATOMIC RADIUS ACROSS THE PERIODIC TABLE?
As you move across the periodic table from left to right (across a period), the atomic radius of the elements tends to decrease.
How does the atomic raduis change across a period of the periodic table?
Atomic radius usually decreases from left to right across a period of the periodic table.
What happens to the atomic radius when you go from left to right on the periodic table of elements?
The atomic radius decrease, with several exceptions in periods 6 and 5.
Does elements on the periodic table decrease in atomic size when you move across a period from left to right and when you move down a group?
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.
Does an element on the periodic table decrease in atomic size when you move across a period from left to right and when you move down a group?
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.
How does the atomic radius change from the left to the right horizontal row in the periodic table?
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
What decreases across the periodic table?
Atomic size decreases across a period
What stays the same across a period on the periodic table?
the atomic number.
When moving across a period in the periodic table?
The atomic number increases
Does atomic radius have a bigger atomic number as you go to the right of the periodic table?
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.
What are patterns in the periodic table?
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.
What increases as you move right across a period in the periodic table?
Atomic number, ionization energy and electronegativity
