The number of each group indicates how many electrons are in the outer shell. Group 1 includes lithium ( electronic configuration 2.1), group 6 includes oxygen(electronic structure 2.6). Remember, the first shell in an atom holds up to two electrons, and the rest of the shells from then on will hold up to eight.
Each period in the Periodic Table ( horizontal layers ) indicates how many shells the atom has. E.g Hydrogen is in the first period as it has 1 shell ( one electron ), lithium in the second because it has 2 shells. ( two electrons in the first, one in the second). This means the bigger the atom, the further towards the bottom of the periodic table it is.
What else can I help you with?
. How does atomic radius change from top to bottom in a group in the periodic table?
It tends to increaseThe atomic radius increases down the group
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.
What happens to the atomic number as you go down the group?
The atomic number increases as you go down a group on the periodic table. This is because each element in a group has one more electron and proton than the element above it, leading to an increase in atomic number.
How does atomic radius vary down a group?
Atomic radius increases down a group on the periodic table because with each additional period an energy level is added.
What properties increase down the periodic table?
Atomic Mass
. How does atomic radius change from top to bottom in a group in the periodic table?

What do you predict the trend in atomic mass will be going down a group?
The atomic mass increases down a group.
How does size change in a period and in a group?
Atomic size decreases across a period as the effective nuclear charge increases. Atomic size increases down a group as the energy level (shells) increases.
What is the Group trend Atomic radius?
The group trend for atomic radius is that it tends to increase down a group in the periodic table. This is because as you move down a group, the number of electron shells increases, leading to a larger atomic radius. Additionally, the effective nuclear charge decreases down a group, which also contributes to the increase in atomic radius.
What happens to the atomic structure as you go down any group?
Down a group, the atomic size (energy level / 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.
What happens to the atomic number as you go down the group?
The atomic number increases as you go down a group on the periodic table. This is because each element in a group has one more electron and proton than the element above it, leading to an increase in atomic number.
What group is the p block in?
Atomic radius increases down the 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.
How does atomic radius vary down a group?
Atomic radius increases down a group on the periodic table because with each additional period an energy level is added.
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.
What properties increase down the periodic table?
