Effective nuclear charge (Z) increases going across a row in the Periodic Table. So when increasing amounts of protons and electrons to an atom(within the same level or row) the protons are more able to hold onto electrons tightly , reducing size.
What else can I help you with?
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 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.
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 as you move down the periodic table?
Down a group, the atomic radius increases as the number of shells or energy levels increases.
What happens to the atomic radius when you go from left to right on the periodic table?
As a general rule, when moving left to right on the periodic table the atomic radius decreases due to increasing electromagnetic attraction of the nucleus to the electrons.
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 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 of the following decrease as you go from left to right on the periodic table?
The atomic radius decreases as you go from left to right. or atomic radius cation radius && anion radius -barbie=]
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 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 is the atomic radius of gallium and how does it compare to other elements in the periodic table?
The atomic radius of gallium is about 135 picometers. In the periodic table, gallium has a larger atomic radius compared to elements to its left and a smaller atomic radius compared to elements to its right.
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 as you move down the periodic table?
Down a group, the atomic radius increases as the number of shells or energy levels increases.
What happens to the atomic radius when you go from left to right on the periodic table?
As a general rule, when moving left to right on the periodic table the atomic radius decreases due to increasing electromagnetic attraction of the nucleus to the electrons.
Which characteristics both generally decrease When the elements in period 3 on the periodic table are considered it order from left to right?
As you move from left to right across period 3 on the periodic table, the atomic radius, metallic character, and reactivity generally decrease. This is because the increasing number of protons in the nucleus leads to stronger attraction for the electrons, resulting in a smaller atomic size and less metallic behavior.
Which atom has larger atomic radius Rb or Xe?
Xe has a larger atomic radius than Rb because atomic radius generally increases from top to bottom within a group in the periodic table. Xe is located below Rb in the periodic table, so it has more electron shells, resulting in a larger atomic radius.
What species has the smallest atomic radius between Kor Mg orRb or Ca?
The species with the smallest atomic radius among K, Mg, Rb, and Ca is Rb (Rubidium). This is because atomic radius tends to decrease across a period from left to right in the periodic table, and Rb is located towards the right side of this group of elements.
