They are called periods because after each period in the following period elements are ordered according to their properties at the intersection with vertical columns (groups) and these properties are periodically reproduced.
The horizontal rows are periods on periodic table. There are 7 horizontal rows in modern periodic table.
Group
False; That would be called groups. Periods are horiztonal rows.
The periodic table contains 18 columns known as groups and 7 rows known as periods. The properties of the elements are found to be periodic when arranged in order of increasing atomic number.
false The vertical columns are known as groups whereas the horizontal rows are known as periods.
False. The vertical columns are known as groups whereas the horizontal rows are known as periods.
Columns are also known as Groups or Families. Rows are also known as Periods or Energy levels
The Periodic Table of the Elements contains every element known to man. On the Periodic Table, the elements are classified into periods (rows) and groups (columns). Elements are placed near elements with similar characteristics to them.
They are called periods because after each period in the following period elements are ordered according to their properties at the intersection with vertical columns (groups) and these properties are periodically reproduced.
The horizontal rows are known as periods. The vertical columns are known as groups / families.
The horizontal rows are periods on periodic table. There are 7 horizontal rows in modern periodic table.
the horizontal rows (not groups) are known as periods.
Group
False; That would be called groups. Periods are horiztonal rows.
