Question

Properties of elements within a..........on the periodic table change in a predictable way from one side of the table to the other

Answer 1

Properties of elements within a blank on the periodic table change in a predictable way from one side of the table to the other. those with similar properties appear in a column. In the periodic table elements are arranged in rows. The rows are also referred to as periods, Elements in the same row (the same period) have the same number of electron shells.

Answer 2

Answer;

-Period

Explanation;

-Properties of elements within a period on the periodic table change in a predictable way from one side of the table to the other. A period in the periodic table is a horizontal row. All elements in a row have the same number of electron shells.

-Elements in the same period have the same number of electron shells; moving across a period, elements gain electrons and protons and become less metallic.This arrangement reflects the periodic recurrence of similar properties as the atomic number increases.
