What else can I help you with?
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?
The atomic radii of main-group elements generally increase down a group. This is because as you move down a group, the principal quantum number increases, leading to larger atomic orbitals and a greater distance between the nucleus and the outermost electron, resulting in a larger atomic radius.
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.
Explain the large decrease in atomic radii as you move across a period from group 1 to group 14?
The decrease in atomic radii across a period from group 1 to group 14 is mainly due to increasing effective nuclear charge. As you move across a period, the number of protons in the nucleus increases, pulling the electrons closer to the nucleus. This results in a stronger attraction between the nucleus and the electrons, leading to a decrease in atomic size.
What happens to the radii of the elements between 2 highest peaks?
The radii of elements generally decrease as you move from left to right across a period in the periodic table. The radii then increase as you move down a group in the periodic table. This trend is due to changes in the atomic structure of the elements.
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.
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.
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 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.
How does the size of elements vary down the group in the periodic table?
Atomic size increases down the group. The number of shells increases causing more atomic radius.
The trend in the atomic radii as you move down the group 1A elements is partially due to what?
The trend in atomic radii as you move down Group 1A elements is partially due to the increase in the number of electron shells or energy levels. As you move down the group, each subsequent element has an additional electron shell, leading to an overall larger atomic size.
