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 trends in size are found among elements in the same period?
The atomic radius decrease from left to right.
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 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 the characteristics of a period in the periodic table?
Elements in a period all have the same number of electron shells (excepting the transition elements). Also, electronegativity increases left to right and up, and atomic radii increase right to left and down.
Which characteristics both generally decrease When the elements in period 3 on the periodic table are considered it order from left to right?
The nonmetallic properties and the atomic radius generally decrease when the elements in period 3 are considered ordered. The order used is from left to right.
What trend in atomic radii do periods 3 through 6 have in common in the periodic table?
Generally is a decrease of atomic radius along a period, from left to right.
Does atomic size decrease going left to right within a period?
It decreases.
What is the general trend in densities for period 2?
Increase from left to middle and decrease from there to the right.
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.

What trends in size are found among elements in the same period?
The atomic radius decrease from left to right.
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.
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 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.
Does an elements electronegativity change when going within a period?
Yes electronegativity changes along a period. It increases along a period.
How does electronegativity increase or decrease in modern periodic table?
Electronegativity increases from left to right across a period and decreases down a group.
