As you move across a period in the Periodic Table from left to right, the atomic radius decreases due to the increasing positive charge of the nucleus. This increased nuclear charge attracts the electrons more strongly, pulling them closer to the nucleus and resulting in a smaller atomic size. Additionally, since electrons are added to the same energy level without significant increase in shielding, the effective nuclear charge felt by the outermost electrons increases, further reducing the 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.
What makes the atomic radius change along the periodic in the periodic table?
Along a period, nuclear charge increases. hence, atomic radius decreases.
What happens to the atomic radius as you move down the periodic table?
Down a group, the atomic radius increases as the number of shells or energy levels increases.
. How does atomic radius change from top to bottom in a group in the periodic table?
It tends to increaseThe atomic radius increases down the group
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 raduis change across a period of the periodic table?
The atomic radius generally decreases across a period of the periodic table from left to right due to increased nuclear charge pulling electrons closer to the nucleus. This results in a stronger attractive force, leading to a smaller 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.
What make the atomic radius change along the periodic in periodic table?
Along a period, nuclear charge increases. hence, atomic radius decreases.
What makes the atomic radius change along the periodic in the periodic table?
Along a period, nuclear charge increases. hence, atomic radius decreases.

How does the atomic radius change from the left to the right horizontal row in the periodic table?
The atomic radius decreases from left to right across a period in the periodic table. This is due to the increasing number of protons in the nucleus, which pulls the electrons closer to the nucleus, resulting in a smaller atomic radius.
Does phosphorus have a larger radius than chlorine?
No, chlorine has a larger atomic radius than phosphorus. Atomic radius decreases as you move from left to right across a period in the periodic table, and phosphorus is to the left of chlorine in 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.
What makes the atomic radius change down Column of the periodic table?
the larger the highest energy level number, the larger the atomic radius (Apex)
Which atom is the smallest among lithium and fluorine?
The smallest atom is lithium, as it has a smaller atomic radius compared to fluorine. This is because as you move across a period on the periodic table, atomic radius decreases due to increased nuclear charge pulling the electrons closer to the nucleus.
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.
