The chart is organized so heavier elements are towards the bottom right.

Why does the size of the elements increase down a group?
The atomic numbers of the elements down a group increase. this means, more electrons. More electrons mean more shells. More shells mean larger radius. Larger radius is nothing but larger size. Thus, the number of electrons or shells is the reason why the size of the atom of elements increase down the group.
Why does electro negativity decrease while going down the periodic table?
Down the group the size of atom increases. Hence the force of attraction between the nucleus and the electrons of the next atom decreases. Or in other words, the electronegativity decreases down the group.
Ionization energy increases as you go down a group?
Answer:False. Because of increased distances between the valence electrons and the nucleus of the atoms (which increase in size as you go down a group) the electrostatic forces holding the electrons are weaker, and so it takes less energy to remove an electron from the atom.
What do you notice about atomic radius as you look down a group?
As you look down a group you notice that the atomic radius increases or becomes larger.
What happens to the size of an atom as you move top to the periodic table?
Size typically increases going down a group due to an increasing number of electron shells, where the inner shells reduce the attractive forces of the nucleus and repel the electrons in the outer shell .

Why metlic character increases from top to bottom in a group of metals?
Down a group, the number of shells increases, also the atomic size. Thus , the metallic character increase does increase as going DOWN a group. It is easy to remove an electron froman atom of bigger...
What happens to the radius of an atom as one goes down a group?
The radius will increase, this is because as you go down there are more electrons and they are put into progressivly larger orbitals so in effect the raidus increases.
Were on the periodic table would you find atoms with the largest atomic radius?
Atomic radius increases down the group. So larger atomic radius are present at the bottom.
Why is there an increase in the size of the atoms as you go down in the periodic table in case of inert gases?
For the elements in all groups, the size of the atom increases down the group. This is because as you descend the group, the number of electrons increases, hence the number of electron shells also increase. For example, the argon atom is bigger than the neon atom because it has one more electron shell (due to 8 more electrons). The extra shell will contribute to a larger atom size.
What are the trends and exceptions to the trends in electron affinity?
Down the group electron affinity decreases Across a period electron affinity increases. However, it should be noted that chlorine is having higher electron affinity than flourine due to the small size of fluorine atom)
What makes the atom radius change down a column of the periodic table?
The larger the highest energy level, the larger the atomic radius.
Why does electro negativity decrease while going down the periodic table?
Down the group the size of atom increases. Hence the force of attraction between the nucleus and the electrons of the next atom decreases. Or in other words, the electronegativity decreases down the group.

Size typically increases going down a group due to an increasing number of electron shells, where the inner shells reduce the attractive forces of the nucleus and repel the electrons in the outer shell .
Which atom has larger atomic radius Rb or Xe?
Rb is larger with a radius of 248 pm while Xe has one of 130 pm. It follows the trend that radii decrease as you move right across the periodic table.
