What does atomic radius do across a period?
It decreases.
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.
Which group of the main group elements contains the largest elements - Atomic Radius?
Group-1 has largest atomic radius. It decreases across a period
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
What does atomic radius do across a period?
It decreases.
How does the atomic radius vary in a period?
Atomic radius decreases across a period from left to right, except for the noble gases.
How does atomic radius vary in group and in period on periodic table?
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.
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 increases down a group and decreases across a period?
Atomic radius
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 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
How are period and group trends in atomic radii are related to electron configuration?
The atomic radius decreases along the elements across a period. Along a group, there is an increment in the atomic radius of corresponding elements.
What happens to size of atoms while moving across the period?
Atomic Radius Decreases from left to right. From left to right the amount of valence shell electrons increases, maxing out at 8. These valence electrons are pulled by the positively charged nucleus, thus making it smaller from left to right.
Which group of the main group elements contains the largest elements - Atomic Radius?
Group-1 has largest atomic radius. It decreases across a period
Atomic size generally as you go down a group?
Atomic size generally increases as you go down a group
