The periods on the Periodic Table separate the elements according to which shell their valence electrons fall into. So, elements located in the third period will have the sum of all electrons contained in that period.
For example: P has an electron configuration of 1s2, 2s2, 2p6, 3s2, 3p3
......................sooo, add up all electrons from the third shell (3s2 & 3p3) to get the total number of valence electrons of the element.

Why some of the periods have different numbers of elements?
The early periods have less elements because they are filling up energy levels which hold only a few electrons. The later periods contain elements with electrons in levels with a greater capacity.
What are the different rows of elements in the periodic table called?
The rows of elements in the periodic table are called periods. There are a total of 7 periods in the periodic table, each representing a different energy level or shell in which the elements' electrons are arranged.
What do we call the horizontal row in the periodic table of elements?
Horizontal rows are called periods. There are 7 periods in periodic table.
What are periods on the periodic table of elements?
Periods on the periodic table are rows that categorize elements based on the number of electron shells they have. There are seven periods in total, each representing a different energy level. Elements in the same period have similar properties due to their electron configurations.
What is a periods on the periodic table?
Periods on the periodic table refer to the horizontal rows that categorize elements based on the number of electron shells they have. There are a total of 7 periods on the periodic table, each representing a different energy level for the elements within that row.
What are the horizon rows containing elements from different groups with different properties called?
The Horizontal Rows are called Periods & the Vertical are Families or Groups.
What are horizontal rows of elements in the periodic table?
Horizontal rows of elements in the periodic table are called periods. Each period represents a different energy level, with elements in the same period having the same number of electron shells. Periods are arranged in numerical order from left to right on the periodic table.
What are the periods on the periodic table and how do they relate to the organization of elements?
The periods on the periodic table are the horizontal rows that indicate the number of electron shells in an atom. Each period represents a different energy level for the electrons. The organization of elements in periods helps to show how the properties of elements change as you move across the table from left to right.
What is the line that separates areas of the newsletter?
The line that separates areas of the newsletter is called a divider or a rule. It is used to visually separate different sections or elements within the newsletter for better organization and readability.
What are the periods in Mendeleev's periodic table?
Because some of the elements were not yet discovered so he left them blank for other elements to be discovered. -bobby corner
Why are the elements on the periodic tables separated into periods?
The elements on the periodic table are separated into periods based on the number of electron shells they have. Elements in the same period have the same number of electron shells, which influences their chemical properties and reactivity.
What delimiter separates domain spaces?
In domain names, the delimiter that separates different parts (or levels) of the domain is the period (or dot). For example, in the domain "www.example.com," the periods separate the subdomain ("www"), the second-level domain ("example"), and the top-level domain ("com"). Each part of the domain represents a different level in the domain hierarchy.
