What trend can be observed among the atomic radii of main-group elements down a group?
Wiki User
∙ 12y ago
Within a group, the number of shells (or energy level) increases (as we go from top to bottom of a group) and hence the size of the atom or the atomic radii increases.

∙ 9y agoThe trend that is observed is that the atomic radii decrease going across a period. Atomic radii increase going down a group.
Wiki User
∙ 11y agoIncreasing atomic number, means increasing nuclear charge, which attracts the electrons more, forming a smaller atomic radius.
Wiki User
∙ 12y agoAmong all the main groups the trend of increasing atomic size down the group is observed.This is because of addition of extra shell as we move down the group.

What trends in size are found among elements in the same period?
The atomic radius decrease from left to right.
What elements boron aluminum gallium or indium has the largest atomic radius?
Atomic radius increases down the group. So indium will have the largest atomic radius among the options given.
Which element has the greatest atomic mass Li Cl C?
Among these three elements, Cl has the greatest mass, as can be seen from any periodic table or other reference work that shows atomic masses.
What basic information is contained in the Periodic table of elements?
The periodic table include only chemical elements each has a unique atomic number that represents the number of protons in its nucleus. Most elements have differing numbers of neutrons among different atoms these are referred to as isotopes.
Write a sentence that describes the purpose of the periodic table?
The elements of the periodic table are arranged in groups and periods. All of the elements in a period have the same number of atomic orbitals where as in a group all the elements have the same number of valence electrons.
Does sodium have the smallest atomic size?
no, hydrogen has the smallest size among all elements

What elements boron aluminum gallium or indium has the largest atomic radius?
Atomic radius increases down the group. So indium will have the largest atomic radius among the options given.
The atomic radius of potassium is smaller than the atomic radius of?
Rubidium; the next higher atomic numbered element in the same column of the periodic table always has a higher atomic radius, with some exceptions among transition elements due to the "lanthanide contraction". However, potassium and rubidium are not transition elements.
What elements has a ground-state electron configuration different from the predicted one?
There are many elements among the transitional elements which has the electron configuration differed than predicted. Such element with the lowest atomic number is chromium.
Which element has the greatest atomic mass Li Cl C?
Among these three elements, Cl has the greatest mass, as can be seen from any periodic table or other reference work that shows atomic masses.

Which element has the largest size of atoms?
Atomic radii have not been measured or calculated based on theoretical principles for all of the elements. However, based on the information available in the wikipedia tables of atomic radii it would appear that the largest atom will prove to be that of francium.
What are the islands where Charles Darwin observed variation among organisms?
Galapagos Islands are the islands where Charles Darwin observed variation among organisms.
What is smaller than the periodic table of elements?
Particles smaller than elements are called sub atomic particles. Among these are: Protons, Neutrons, Electrons, Photons, Gluons, Mesons, Bosons, Muons, Quarks, and more.
Why periodic table was identified?
The periodic table was not 'identified.' It is simply all known elements ordered by similar qualities and atomic number, among other things.
