the size of atom doesn't decrease regularly due to the reason of lanthanide contraction .there is slightly increase or or almost no increase in atomic radius from 5th to 6th period in transition metal .

as we know that there are 7 periods and 18 groups ,as we go down a group the size of the atom decreases therefore there is a decrease in ionization energy for
As the atomic number increases, the number of protons in the nucleus increases or the effective nuclear charge of the nucleus increases. As a result the force exerted by the nucleus on the valence electrons is more or the size of the atom is small.
1. In a period is a trend of decrease from left to right but it is not absolute.2. In a group the atomic radius increase moving down.
Chlorine is in 3rd period and 17th group bromine is in 4th period and 17th group. The number of shells present in an atom is equal to the period no. In which it is present. So, chlorine has 3 shells while bromine has 4 shells. And atomis size is the distance between centre of nucleus and outermost shell. So, bromine atom is larger than bromine atom..
The atom itself would be the size of an NFL stadium.

They begin to split, almost like a nuclear atom; the more you put on to it the more it splits
The size of kidneys don't usually decrease in size over time.
By the size of the atom and its mass
