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 does atomic radius do across a period?
Atomic radius tends to decrease across a period from left to right. This is because as you move across a period, the number of protons in the nucleus increases, leading to an increase in the effective nuclear charge felt by the outermost electrons, which pulls them closer to the nucleus.
Which group of the main group elements contains the largest elements - Atomic Radius?
Group-1 has largest atomic radius. It decreases across a period
In general howe dose atomic radius change across a period from letf to right?
Atomic radius generally decreases across a period from left to right. This is due to the increasing nuclear charge pulling the electrons closer to the nucleus, making the atomic size smaller.
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.
An increase in the atomic number the atomic radius moving from left to right across a period.?
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.
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 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.
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.
What does atomic radius do across a period?
Atomic radius tends to decrease across a period from left to right. This is because as you move across a period, the number of protons in the nucleus increases, leading to an increase in the effective nuclear charge felt by the outermost electrons, which pulls them closer to the nucleus.
Which group of the main group elements contains the largest elements - Atomic Radius?
Group-1 has largest atomic radius. It decreases across a period
Which element in the 2 period has the greatest atomic radius?
Neon (Ne) in the second period on the periodic table of the elements has the highest atomic number in that period of 10.
In general howe dose atomic radius change across a period from letf to right?
Atomic radius generally decreases across a period from left to right. This is due to the increasing nuclear charge pulling the electrons closer to the nucleus, making the atomic size smaller.
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.
