In the periodic table of the elements, a period is a horizontal row of the table. Elements in the same period have the same number of energy levels.

Periods in the Periodic Table go horizontally from left to right. Each period represents the number of electron shells an atom has.

What is the difference between a period and a group on the periodic table?
A period on the periodic table refers to a horizontal row of elements, while a group (or family) refers to a column of elements with similar properties. Periods indicate the number of electron shells an atom has, whereas groups reflect the number of valence electrons an element possesses.
What is the pattern of the periods on the periodic table?
The periods on the periodic table represent the number of energy levels an atom's electrons occupy. As you move from left to right across a period, the number of protons and electrons increases, resulting in an extra electron being added to each subsequent element.
What happens to the atomic number as you go from left to right across the periodic table and why does this happen?
The atomic number increases from left to right across the periodic table because the number of protons in the nucleus of an atom increases. This results in a higher positive charge, leading to a stronger attraction to electrons and a closer binding of electrons to the nucleus.
What are periods and groups?
Periods in the periodic table refer to the rows that categorize elements based on the number of electron shells they have. Groups, on the other hand, are the columns that group elements with similar chemical properties based on the number of electrons in their outermost shell (valence electrons).
What is a row in a the periodic table called?
A row of the periodic table is known as a period.Related Information:Across a period, you can see how the electrons fill the energy levels from the s sub-level to the p sub-level. The highest-filled energy levels correspond to the row, or period, number. Down a group, you can see how many valence electrons are present in the atoms of each element.
What are the names of the periods on the periodic table?
The periods on the periodic table are labeled numerically from 1 to 7. Each period represents the number of energy levels or electron shells in an atom.
How are groups on a periodic table numberd?
From right to left (1- 18) on the periodic table. Instead of up and down (1-7) periods go vertically. (rows) groups go horizontally. (columns)
What are the seven rows of the periodic table are commonly called?
groups go vertically and periods are the horizontal rows
What is the difference between a period and a group on the periodic table?
A period on the periodic table refers to a horizontal row of elements, while a group (or family) refers to a column of elements with similar properties. Periods indicate the number of electron shells an atom has, whereas groups reflect the number of valence electrons an element possesses.
How are the elements in the periods in the periodic table related?
As you go down a group, the number of electrons in the outer shell is the same.
Which direction are families on the periodic table?
groups on the periodic table are the vertical coumns that go up and down. A period on the periodic table are the rows that go horizontal or across.
Do periods go across or down?
Periods in a sentence typically go across from left to right. Each period is placed after a complete thought or at the end of a sentence to indicate a pause.
What does GO stand for in the periodic table?
there is no Go on the periodic table, there is Gd, Ga, Ge, but no Go. Hope this helped!
When is it necessary to start a new period in the periodic table?
Periods in the periodic table represent the number of electron shells necessary to fit all of the electrons. Once you fill the valence shell of an atom, the next electron must go in a new electron shell. This would constitute a new period on the periodic table.
What is a period in a periodic table?
A period in the periodic table is a row of elements that share the same outer electron configuration. There are a total of 7 periods in the periodic table. Elements in the same period have similar chemical properties.
How do you know if a metal is a transitional metal?
go loook at a periodic table. there are 8 tall periods, the middle periods that are shorter then all the rest, after the two first ones, those are the transitional metals.
What is the pattern of the periods on the periodic table?
The periods on the periodic table represent the number of energy levels an atom's electrons occupy. As you move from left to right across a period, the number of protons and electrons increases, resulting in an extra electron being added to each subsequent element.
