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 atomic radius vary down a group?
Atomic radius increases down a group on the periodic table because with each additional period an energy level is added.
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.
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.
What trend does the atomic radius along a period on the periodic table?
The atomic radius decreases along a period. It is because of increasing effective nuclear charge along a period.
What is the atomic radius phosphorus?
The atomic radius of phosphorus is approximately 110 picometers (pm) or 1.1 angstroms (Å). This value can vary slightly depending on the specific allotrope of phosphorus and the method of measurement. Phosphorus, located in group 15 of the periodic table, has a relatively smaller atomic radius compared to elements in the same period, such as silicon and sulfur.
what element has largest atomic radius in 3rd period elements?
In the third period of the periodic table, sodium (Na) has the largest atomic radius. As you move from left to right across a period, the atomic radius decreases due to increasing nuclear charge, which pulls electrons closer to the nucleus. Sodium, being the first element in the period, has the least effective nuclear charge acting on its outer electrons, resulting in a larger atomic radius compared to the other elements in the third period.
What element in the second period has the smallest atomic radius?
Fluorine
Why does indium have the largest atomic radius?
Indium has the largest atomic radius among elements in its period because of the shielding effect. With more electron shells, the outer electrons are further from the nucleus, resulting in a larger atomic radius.
Why does sodium have a larger atomic radius than aluminum?
Sodium has a larger atomic radius than aluminum because as you move down a group in the periodic table, the atomic radius increases due to the addition of energy levels. Sodium is located in the third period, while aluminum is in the second period, so sodium has more energy levels and a larger atomic radius.
What is the smallest atomic radius in period 5?
The smallest atomic radius in period 5 belongs to the element with the highest nuclear charge, which is iodine (I) from Group 17. This is because as you move across a period, the nuclear charge increases, leading to stronger attraction for the electrons and a smaller atomic radius.
What makes the atomic radius change along the periodic in the periodic table?
Along a period, nuclear charge increases. hence, atomic radius decreases.
