The size of atoms does not decrease regularly across a period due to the competing effects of increasing nuclear charge and electron shielding. As you move from left to right across a period, the number of protons increases, leading to a greater positive charge in the nucleus, which attracts electrons more strongly. However, the added electrons occupy the same principal energy level and do not significantly increase shielding, resulting in a more effective pull on the electrons and a decrease in atomic radius. This trend can be influenced by factors like electron-electron repulsion and the presence of d or f orbitals, leading to irregularities in atomic sizes.

Do the size of kidneys decrease with time?
The size of kidneys don't usually decrease in size over time.
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.
What is the size is an atom?
The size of an atom refers to the typical distance from the nucleus to the boundary of the surrounding cloud of electrons.
How is the size of an anion different from the size of the atom from which it was formed?
Anion will have more electron than which atom it was form. So, after forming the the atom will have more electron cloud and size will be smaller compare to the original one.

Why the size of an atom does not decrease regularly in a period?
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.
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.
When nonmetals lose electrons and become positives does the size increase or decrease?
They begin to split, almost like a nuclear atom; the more you put on to it the more it splits
