When we move from left to right there are completely half and partially filled orbitals present so the attraction of nucleus are not regular because half and completely filled orbitals electrons are more attracted toward the nucleus but partially filled are not that's why atomic size not decrease regularly in a period.

What trends in size are found among elements in the same period?
The atomic radius decrease from left to right.
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.
Do the size of kidneys decrease with time?
The size of kidneys don't usually decrease in size over time.
How is electronegativity related to atomis size?
Electronegativity is the ability of an atom to attract shared electrons in a chemical bond. It tends to increase as you move across a period from left to right due to increased nuclear charge. In contrast, atomic size generally decreases across a period from left to right due to increased nuclear charge pulling electrons closer to the nucleus.
What is the atomic size of an atom?
The atomic size of an atom refers to the distance between the nucleus of the atom and the outermost electron shell. It is typically measured as the radius of the atom. Atomic size generally increases as you move down a group on the periodic table due to the addition of electron shells, and decreases as you move from left to right across a period due to increased nuclear charge.
Why the size of an atom does not decrease regularly in a period?
The size of an atom in a period does not decrease regularly due to variations in the effective nuclear charge experienced by the electrons. As you move across a period, electrons are added to the same energy level, causing increased nuclear charge which pulls the electrons closer and decreases the atomic size. However, the shielding effect from inner electrons is not constant, leading to fluctuations in atomic size across a period.

Does atomic size decrease going left to right within a period?
It decreases.
What trend do you note for the atomic radii of period 3?
The size of atom decreasing.
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.
What trends in size are found among elements in the same period?
The atomic radius decrease from left to right.
Size of cation is smaller than its neutral atom?
When an atom loses an electron to become a cation, it loses an electron shell which results in a smaller size compared to the neutral atom. This is because the electrons that previously occupied the outermost energy level are now lost, leading to a decrease in atomic size.
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.
Do the size of kidneys decrease with time?
The size of kidneys don't usually decrease in size over time.
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
The volume of an atom is determined by the size of?
By the size of the atom and its mass
Why does the size of the elements decrease across a period?
In a period, the number of shells of all the elements is same. So, this basically means that all must have the same radius or same size. but, this is not the case because, as we move across a period, one electron gets added. So, as the negative charge of the atom keeps increasing or as the atomic number keeps increasing, the number of positively charged protons also keeps increasing. This means, there is more nuclear force of attraction between the nucleus ( where protons are present) and electrons of the atom. Thus, this nuclear force causes the nucleus to hold on to the electrons more tightly ,i.e, the electrons get closer to the nucleus which means the shells which contain the electrons are pulled closer. This means, the atom's radius keeps decreasing. Thus, across a period, the atomic size decreases due to the increasing nuclear force of attraction.
