What happens to the atomic radii of the elements as a group is descended?
As we descend down the group, the atomic radii increases. This is because the number of shells increases.
What trend can be observed among the atomic radii of main-group elements down a group?
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.
Explain the large decrease in atomic radii as you move across a period from group 1 to group 14?
Atomic radius increases down the group due to increase in no.of orbits around the nucleus.
What is the trend in atomic radius down a group explain?
the atomic radii increases down the group.
Why reactivity of metal increases down the group?
As we go down the group, nuclear charge deceases and atomic radii increases. So the element can easily lose electron and hence react.
Why are the radii changing as you move down the table within a column?
Radii generally decrease from left to right along each period (row) of the table, from the alkali metals to the noble gases; radii increase down each group (column). The radius increases sharply between the noble gas at the end of each period and the alkali metal at the beginning of the next period
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 ionic radius change as you move down and across the periodic table?
Ionic radius (or radii) increases as you move down a group and across a period.
Which elements has the largest atomic radii in periodic table?
The atomic radii of members of the Group 1A (Alkali metals), increases down the group. Therefore Francium has the largest atomic radius of the Alkali metals. However Fr has no stable isotopes, thus is not naturally occurring. So Cs-133 is the largest you can find.
What trend is oberserved among the atomic radii of main-group elements down a group. eplain this trend?
The trend of atomic radius increases down a group on the periodic table. This occurs because each successive element down a group has another energy level. As more electrons are added, more energy levels are needed to hold the electrons.
What is the similarity and the difference between the two elements found in the same group?
As we move down the group ,the electrons in the valence shell remains constant but the number of shells increases by one.size of the element increases down the group .elements are more electro-positive as we move down the group so elements at the bottom are more electro-positive than those at the top.as the size of the elements increases the nuclear charge on the elements decreases.due to less nuclear charge shielding effect decreases down the group.
What happens to the reactivity as you move down group 1 in the periodic table?
Reactivity in group 1 of elements increases as we go down the group (to francium) because in the alkali metals as we go down the group number of atomic shells increases so the elements with most shells will easily release their electrons in the outer most shell.
