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.
What else can I help you with?
Where are the periods located on the periodic table?
Periods on the periodic table are the horizontal rows that go from left to right.
What is the difference between a period and a group on the periodic table?
Periods on the periodic table go across and are based on the number of unexcited electrons increasing as you read across. Groups on the periodic table are read down the table and share the same number of valence electrons.
What is the pattern of the periods on the periodic table?
I hope I'm not too late! On the left side, the atoms are smaller and as you go across they get bigger but this pattern works like a typewriter... when you get back to the left again they start out small and grow again and so on. on the top, the atoms are less radioactive. Guess what goes on in the bottom? Duh, very radioactive. Hope I helped!!!The rows in The Periodic Table of Elements, as you read it, the rows are considered to be a different period. ( Period-ic Table.) Elements have something in common if they are in the same row. All the elements in a period or row have the same number of atomic orbitals. All the elements in the top row (first period) have one orbital for its electron. The second row (second period) has two electrons orbiting. The columns have special names and rules too. A column is called a group. The elements in a group have the very same number of electrons in their outer orbital. Every element in group one has one electron in its outer shell. (and so on.)Hope it helped. I copied it from my Periodic Table Essay for school.The above answer is also correct. I am just specifying.
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?
Elements in the periodic table are arranged in periods (rows) and groups (columns). Atomic number increases as you move across a row or period. The period number of an element signifies the highest unexcited energy level for an electron in that element. Elements within a group share several common properties. Groups are elements have the same outer electron arrangement. The outer electrons are called valence electrons.
Where are the periods located on the periodic table?
Periods on the periodic table are the horizontal rows that go from left to right.
What are the names of the periods on the periodic table?
Periods are the elements on the periodic table that go across, in rows. So basically going across each row is called a period
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?
Periods on the periodic table go across and are based on the number of unexcited electrons increasing as you read across. Groups on the periodic table are read down the table and share the same number of valence electrons.
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 go across the periodic table. Groups go down.
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!
What is a period in a periodic table?
a row going acrossNOT to be confused with groups or families which go down in columns and have to do with valence electrons
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.
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.
