Along a period, nuclear charge increases. hence, atomic radius decreases.
Atomic radius increases down a group due to increase in number of shells. Its value decreases along a period due to increase in nuclear charge.
The atomic radius gets smaller the farther right it appears on the Periodic Table, until the addition of a new orbital increases the size again.
As you move from left to right along a period in the periodic table, the atomic radius decreases. This is primarily due to the increasing positive charge of the nucleus, as more protons are added, which leads to a stronger attraction between the nucleus and the electrons. Although electrons are also being added, they enter the same energy level without significantly increasing electron shielding, resulting in a net decrease in atomic size. Consequently, the greater effective nuclear charge pulls the electron cloud closer to the nucleus, reducing the atomic radius.
Electronegativity decreases along a period. This is because atomic radius increases increases, hence nuclear charge decreases.
Barium has the largest atomic radius among the alkaline earth metals because it is located at the bottom of Group 2 on the periodic table. As you move down a group, additional electron shells are added, increasing the distance between the nucleus and the outermost electrons. This increased distance, along with the shielding effect from inner electrons, results in a larger atomic radius. Additionally, the effective nuclear charge experienced by the outer electrons does not increase significantly enough to counteract the increase in radius due to additional electron shells.
Along a period, nuclear charge increases. hence, atomic radius decreases.
The atomic radius decreases along a period. It is because of increasing effective nuclear charge along a period.
More protons in the nucleus pull the electrons in, making the atomic radius smaller.
The atomic radius gets smaller the farther right it appears on the Periodic Table, until the addition of a new orbital increases the size again.

Periodic trends are patterns that are observed as you move across or down the periodic table of elements. These trends include atomic radius, ionization energy, electronegativity, and metallic character, among others. They help predict the properties of elements based on their position in the periodic table.
I'm guessing you are acking Atomic Radius. The atomic radius decreases and you go left to right because the shielding effect from the lower electrons stays almost constent while the elements gain more protons adding to the effective nuclear charge pulling the electrons closer to the nucleus.
