As more energy levels are occupied by electrons, the atomic radius gets larger.

What is an atomic group?
Each column going down the periodic table is an atomic group.
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 best explains the observed trend in atomic radii going down periodic table?
The more energy levels that are occupied by electrons, the larger the atomic radius.
How does electronegative change going down and across the periodic table?
Electronegativity increases across (left to right) the periodic table and decreases on going down.
What trend is generally observed in electronegativity going across the periodic table from left to right?
From left to right and into the upper corner of the periodic table electronegativity increases. Fluorine is the most electronegative element, but the elements in group 18 generally have no electronegativity at all.
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 is an atomic group?

How do elements change going down the periodic table?
Down a group, the atomic number generally increases, size increases, ionization energy decreases, reactivity increases.
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 best explains the observed trend in atomic radii going down periodic table?
The more energy levels that are occupied by electrons, the larger the atomic radius.
How does electronegative change going down and across the periodic table?
Electronegativity increases across (left to right) the periodic table and decreases on going down.
Why does the atomic size increase when going left to right on the periodic table?
Mostly because there is an increase in the number of electrons. As you add more electrons, there is a larger Coulombic force repelling the electrons away from each other, and this makes the electon "cloud", and therefore the atom larger.
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 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 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.
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.
