the number of protons increases
A row of elements across the periodic table is called a period. Periods represent the number of electron shells in an atom.
A horizontal row on the periodic table of elements is called a period.
periodic table
Some good questions about periodic table: where are metalloids placed? why group 18 elements are inactive? How many groups and periods are in periodic table? How reactivity changes across and down the group?
It is named The PERIODIC TABLE. The periods being the horizontal rows The groups being the vertical columns.
The radii of elements generally decrease as you move from left to right across a period in the periodic table. The radii then increase as you move down a group in the periodic table. This trend is due to changes in the atomic structure of the elements.
Groups of the Periodic Table of Elements.
Is the Periodic Table. The columns down are the GROUPS The lines across are the PERIODS.
It is called the Periodic Table of Elements.
alot of changes
Periodic trends refer to the repeating pattern of properties of elements as you move across a period or down a group on the periodic table. These trends can be recognized by observing how a particular property (such as atomic radius, electronegativity, or ionization energy) changes in a predictable way based on the element's position in the table. By comparing the properties of elements in a specific order, you can identify and analyze periodic trends.
There are 53 Elements in the Periodic Table.
