Which best explains that observed trend in atomic radii going down the periodic table?
Atomic radii increase down a group in the periodic table primarily due to the addition of electron shells. As new electron shells are added, the distance between the nucleus and the outermost electrons increases, resulting in a larger atomic size. Furthermore, the increased shielding effect from the inner electron shells reduces the effective nuclear charge felt by the outer electrons, allowing them to spread out further from the nucleus. This combination of added shells and shielding leads to the observed trend of increasing atomic radii.
What is the first metal in the periodic table?
The first metal in the periodic table is lithium, with atomic number 3.
Which best explains the observed trend in atom radii going down the periodic table?
As you move down the periodic table, atomic radii increase primarily due to the addition of electron shells. Each successive element in a group has an additional energy level of electrons, which increases the distance between the nucleus and the outermost electrons. Additionally, while nuclear charge increases, the effect of increased shielding from inner-shell electrons reduces the effective nuclear charge felt by the outermost electrons, allowing them to occupy a larger volume.
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.
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 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.

What property increases going down a group in periodic table?
Atomic size increases going down a group in the periodic table. This is because additional energy levels are being filled with electrons, leading to an increase in distance between the nucleus and the outermost electron shell.

What is periodic table or periodic chart?
The periodic table or chart is a display of all chemical elements which are ordered by atomic number.the atomic number simply tells you how many electrons there are in the atom. It was created by Dmitri Mendeleev then helped change by Henry Moseley because Dmitri Mendeleev had ordered it in atomic mass. It is used to predict where chemical elements are going to be found and where.
What property increases going down the periodic table?
The atomic radius increases going down the periodic table due to the addition of more electron shells around the nucleus, leading to increased shielding effect and weaker attraction between the electrons and the nucleus.
What happens to the atomic numbers on the periodic table looking from left to right?
it grows one more with each element going right
Where are new elements placed on the periodic table?
You'd need to either discover them or create them. All elements with atomic numbers 1 through 116 have been discovered or synthetically created, as well as 118. 117 hasn't officially been observed, however.
Why do atomic radii generally get larger going down the periodic table?
Atomic radii generally increase going down the periodic table because the number of electron shells increases, leading to a larger atomic size. Additionally, the increasing nuclear charge is offset by increased electron shielding in larger atoms, allowing the outermost electrons to be further from the nucleus, making the atom larger.
