What trend in atomic radius occurs going down on the periodic table and why?

Atomic radii increases moving down a group in the Periodic Table due to the increasing energy levels in the electron configuration and electrons filling in energy levels further away from the nucleus.

How does the atomic radius change from top to bottom in a group 1 and 2 in the periodic table?
Going down and to the left on the periodic table, atomic radius increases. Therefore, the smallest atomic radius is that of Helium (He), and the largest is that of Francium (Fr). Coincidentally, these are also the most and least reactive elements.
What trend is seen atom size going down the periodic table?
Excepting groups 5-12 of the periodic table.the atomic radius increase down in the group.
What is the first metal in the periodic table?
Going by atomic number, Lithium (Li) is the first metal present with the atomic number of 3.
What is the atomic number of NaCI?
Atomic numbers are only given to individual elements. I'm not sure what you were going for here, but only individual atoms (Na or Cl) have atomic numbers. See the periodic table.
How does density change by going down the periodic table?
Atomic radius are increase so density change by going down the periodice table
What property increases going down a group in periodic table?
Atomic size, number of shells (or energy levels) and electropositivity increases down a group on the periodic table.
What property increases going down the periodic table?
Your question is incorrect. It should be increases rather than decreases. Well it is the proton number (Z) that increases.
Smallest to largest atomic radius PotassiumMagnesiumCalciumRubidium?
mg, ca,k ,rb magnesium, calcium, potassium, rubidium as you do down a group atomic radius increases as you go across a period atomic radius decreases

Why do atomic radii generally get larger going down the periodic table?
As more energy levels are occupied by electrons, the atomic radius gets larger.
What explains the observed trend in the atomic radii going down the periodic table?
The more energy levels that are occupied by electrons, the larger the atomic radius.
Which of the following has the smallest atomic radius P AL S Si Cl?
Atomic radius increases going down the periodic table and going from right to left, meaning that Fr (Francium) has the largest atomic radius and He (Helium) has the smallest. Therefore, Cl<S<P<Si<Al So the answer is Cl
What trend is seen atom size going down the periodic table?
Excepting groups 5-12 of the periodic table.the atomic radius increase down in the group.
What is an atomic group?
Each column going down the periodic table is an atomic group.
What happens to the atomic radius as the atomic number increases?
Going across a row in the peiodic table, the atoms have more protons and electrons causing a stronger attractive force, pulling the electrons closer to the nucleus, making the atomic radius decrease. As a new shell is added ( next row down) the atomic radius increases
What trend in ionization energy occurs going down on the periodic table and why?
when you go down a group you get more shells and in those shell are electrons the further away the electrons are from the protons and neutrons the less energy you need to pull of the electrons.
What is the general trend of atomic radius?
When looking at a periodic table, atomic radius increases from top to bottom, and decreases from left to right. The bottom left corner is the largest, while the top right corner is the smallest radius.
