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
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.
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.
An increase in the atomic number the atomic radius moving from left to right across a period.?
decreases
Does the atomic radius decrease as you move up a group and across a period from left to right on the periodic table?
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.
What trends in size are found among elements in the same period?
The atomic radius decrease from left to right.
What accompanies an increase in atomic number within a specific period?
An increase in atomic number would be accompanied by a decrease in radius, and an increase in electronegativity.
What trends can be noticed in the periodic table in terms of atomic radii?
The general trend is a decrease in size as you move from left to right . This is apparent in periods 2 and 3 but in period 4 and above we have the transition metals and these have some exceptions. This is due to the fact that as we moves from left to right along a period while the nuclear charge increases we are also adding extra electrons but the effective charge is mainly affected by the inner core electrons that "shield" the outer electrons. The effective nuclear charge, the charge felt by the outer electrons, increases across a period thus causing a contraction in the shell.
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.
What is the correlation of ionization energies to atomic radii for the elements?
In a group the ionization energy decrease when the atomic radius increase; in a period this relation is not generally valid.
Why does argon have the smallest atomic radius in period 3?
Argon doesnt have the smallest atomic radius, its chlorine.Argon has the largest atomic radius in period 3.
