The atomic weight (not mass) increase from left to right in a period.
As you move across the periodic table from left to right (across a period), the atomic radius of the elements tends to decrease.
The atomic number of an element is the number of protons in the nucleus of one atom of that element. In general, atomic numbers increase as you move to the right and down in the table.
One can recognize a periodic trend on the Periodic Table by observing properties of different elements from the left side to the right side of the periodic table.
Elements on the periodic table follow a trend where their properties show a periodic repetition based on their atomic number. This trend is known as periodicity and is the basis for organizing elements into groups and periods based on their similar characteristics.
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.

One trend that can be identified on the periodic table is the periodicity of elements, which refers to the repeating patterns of properties such as atomic number, atomic mass, and chemical reactivity across rows and columns.

Density increases down a group on the periodic table. The trend is more complex across a period. Metals are generally more dense than nonmetals, but among metals on a period, density increases to the right.
The trend in ionization energy of period 3 elements on the periodic table generally increases from left to right.
As you move left to right on the periodic table, the elements generally have increasing atomic number, increasing atomic mass, and a gradual change in chemical properties. The trend shows a transition from metals to nonmetals with a shift in electronegativity and atomic size.
