Along a period, nuclear charge increases. hence, atomic radius decreases.
It tends to increaseThe atomic radius increases down the group
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 increases down a group on the periodic table because with each additional period an energy level is added.
The atomic radius decrease, with several exceptions in periods 6 and 5.
Along a period, nuclear charge increases. hence, atomic radius decreases.
Along a period, nuclear charge increases. hence, atomic radius decreases.
Atomic radius usually decreases from left to right across a period of the periodic table.
More protons in the nucleus pull the electrons in, making the atomic radius smaller.
The atomic radius decreases along a period. It is because of increasing effective nuclear charge along a period.
Down a period the atomic radius increases as the number of shells (or energy levels) increases. Across a period the atomic radius decreases as the effective nuclear charge increases.
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
It tends to increaseThe atomic radius increases down the group
As you move across the periodic table from left to right (across a period), the atomic radius of the elements tends to decrease.
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.
Decreases. Look at the images under atomic radius, on wikipedia.
The atomic radius gets smaller the farther right it appears on the Periodic Table, until the addition of a new orbital increases the size again.
