The size of an atom does not decrease regularly in a period due to the increasing nuclear charge as you move across the period. The increasing number of protons in the nucleus attracts the electrons more strongly, leading to a greater effective nuclear charge. This increased attraction causes the electrons to be pulled closer to the nucleus, resulting in a smaller atomic size. However, there are exceptions such as the noble gases which have stable electron configurations and do not follow this trend.

What accompanies an increase in atomic number within a specific period?
An increase in atomic number within a specific period corresponds to an increase in the number of protons in the nucleus of the atom. This leads to a higher positive charge, causing the outer electrons to be more strongly attracted to the nucleus. As a result, the atomic size tends to decrease across a period as atomic number increases.
Which atom is the smallest in size?
The atom that is smallest in size is the hydrogen atom.
Size of cation is smaller than its neutral atom?
Yes, the size of a cation is smaller than it's neutral atom. This is so because cations have a low number of shells and hence a high effective nuclear charge which causes them to be smaller in size then their neutral atoms.
How can one improve the ranking of basicity in chemical compounds?
To improve the ranking of basicity in chemical compounds, one can increase the availability of lone pairs on the nitrogen atom, increase the size of the alkyl groups attached to the nitrogen atom, and decrease the electronegativity of the atom directly attached to the nitrogen atom.
If the nucleus of an atom were the size of a marble then the atom itself would be the size of?
The atom itself would be the size of an NFL stadium.

Does an element on the periodic table decrease in atomic size when you move across a period from left to right and when you move down a group?
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.

To improve the ranking of basicity in chemical compounds, one can increase the availability of lone pairs on the nitrogen atom, increase the size of the alkyl groups attached to the nitrogen atom, and decrease the electronegativity of the atom directly attached to the nitrogen atom.
Do the size of kidneys decrease with time?
The size of kidneys don't usually decrease in size over time.
The volume of an atom is determined by the size of?
By the size of the atom and its mass
