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.

What trend can be identified on the periodic table?

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.


How much does the atomic number increase bye as you go across a row on the periodic table?

The atomic number increases by one as you go across a row on the periodic table. Each element in the row has one more proton in its nucleus than the previous element, which is reflected in the increase in atomic number. This trend continues across each row of the periodic table.


What is the trend that the elements on the periodic table abide by?

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.


What is the trend from left to right for atomic mass on the periodic table?

The atomic weight (not mass) increase from left to right in a period.


What trend does the atomic radius follow along period on the periodic table?

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.

How does one recognize a periodic trend on a periodic 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.

A repeating pattern


What explains the observed trend in the atomic radii going down the periodic table?

The more energy levels that are occupied by electrons, the larger the atomic radius.


What trend pattern do you see as you move left to right on the periodic table?

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.
