How does Atomic Radius behave along the Periodic Table?
Atomic radius increases down a group due to increase in number of shells. Its value decreases along a period due to increase in nuclear charge.
An increase in the atomic number the atomic radius moving from left to right across a period.?
decreases
Why does argon have the smallest atomic radius in period 3?
Argon doesnt have the smallest atomic radius, its chlorine.Argon has the largest atomic radius in period 3.
How does calcium atomic radius compare to magnesiums radius and potassiums radius?
Calcium has a larger atomic radius than magnesium and a smaller atomic radius than potassium. This trend is due to the increase in number of protons and electrons as you move across the period on the periodic table from magnesium to calcium to potassium.
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 accompanies an increase in atomic number within a specific period?
An increase in atomic number within a specific period corresponds to an increase in the number of protons in the nucleus of the atom. This leads to a higher positive charge, causing the outer electrons to be more strongly attracted to the nucleus. As a result, the atomic size tends to decrease across a period as atomic number increases.
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 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.
Atomic size generally as you go down a group?
Atomic size generally increases as you go down a group
What is the relationship of ionic radius and atomic number?
As you move across a period from left to right, the atomic number increases and the ionic radius decreases. This is because the increase in positive charge in the nucleus attracts the electrons more strongly, pulling them closer to the nucleus, leading to a decrease in ionic radius.
How does the atomic radius increase or decrease horizontally on the periodic table?
Atomic radius decreases horizontally in periodic table. This is due to increase in nuclear charge.
