A period in the periodic table is a row of chemical elements. All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor. Arranged this way, groups of elements in the same column have similar chemical and physical properties, reflecting the periodic law. For example, the halogens lie in the second-last column and share similar properties, such as high reactivity and the tendency to gain

You can tell the characteristics of an element by looking at its location on the table. The periodic table has gone through many changes since Dmitri Mendeleev drew up its original design i The periodic table currently organizes more than 100 named elements and several unnamed ones. Learn about the periodic table. Advertisement It's human nature to organize things. Cooks painstakingly organize their spices into various groupi The horizontal rows on the periodic table of the elements are called periods.
Atoms of different elements …
A period 1 element is one of the chemical elements in the first row (or period) of the periodic table of the chemical elements. The periodic table is laid out in rows to illustrate periodic (recurring) trends in the chemical behaviour of the elements as their atomic number increases: a new row is begun when chemical behaviour begins to repeat, meaning that analog elements fall into the same vertical columns. A period in the periodic table is a row of chemical elements.
