Actinides and 14 elements in actinides
periodsThere are seven periods, or rows, on the periodic table.
The seven horizontal rows of the periodic table are called periods. They are related by the increasing number of protons in the nucleus of the atoms as you move from left to right across a period. This results in a gradual change in the chemical properties of the elements within a period.
The horizontal rows are called periods, there are 7. The vertical rows are groups and there are 18.
The seven horizontal rows of the periodic table are called "periods". They are numbered from 1 to 7, with each period representing the energy level or shell in which the elements in that row have their outermost electrons. As you move from left to right across a period, the number of protons in an element's nucleus increases, resulting in a gradual change in properties.

Horizontal row in a periodic table is called Period.There are seven periods in a periodic table.All elements in a row have same number of electronic shells.
The horizontal rows are called periods, there are 7. The vertical rows are groups and there are 18.
The horizontal rows in the periodic table are known as periods. There are seven periods in the periodic table, each representing a different energy level or shell in which the elements' electrons are located.
Typically, there are ten horizontal rows on a standard keyboard. This includes the top row (numbers and special characters), the second row (QWERTYUIOP), the third row (ASDFGHJKL), and the bottom row (ZXCVBNM).
A horizontal row in the periodic table is called a period. There are seven periods in the periodic table, labeled from 1 to 7. Each period represents the energy levels of the elements within that row.
There are more than 3 elements in group seven, and they are called halogens.
