All of the elements in a period (row) have the same number of atomic orbitals also known as Valence Electrons. Every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons. It goes down the Periodic Table like that. At this time, the maximum number of electron orbitals or electron shells for any element is seven.
Do you mean groups (veritcal) or periods (horizontal)? Groups are organized in a way to show the number of valence electrons (number of electrons on outer most energy level) which shows that the chemical properties are similar.
Group 2 elements are Alkaline earth metals
They are all shiny, silvery-white, somewhat reactive metals at STP and readily lose their two outermost electrons to form cations with charge 2+ and an oxidation state, or oxidation number of +2
Valence electrons and a love for a certain favor of pie
All of the elements in the row have the same number of electron shells.
they all have the same number of core electrons
The elements in same row have same number of shells.The rows are termed as periods.
The most corrosive elements on the Periodic Table are all of the halogens.
CO2 is not on the periodic table. The periodic table of elements, funnily enough houses all the elements. CO2 is a compound made up of other elements and therefore isnt on the table.
A group is a column in the periodic table of elements.
All the Group 14 elements has 4 electrons in its outer energy level.
All matter on earth is made out of the elements and combinations of the elements in the periodic table. There is nothing on earth that does not have one or more of the elements in it.
The periodic table contain all chemical elements, placed in a rational order.
they are all part of the Periodic Table:)
It is called the Periodic Table of Elements.
Not all the elements in the periodic table are renewable.
The most corrosive elements on the Periodic Table are all of the halogens.
All the elements from the periodic table can be obtained as pure elements.
All of the elements are on the periodic table of the elements. Refer to the related links for a printable periodic table.
they all have the same electrons.
All of them, the periodic table has all of the elements the human discovered or made..
Periodic table comprises of all the elements. There are variety of elements in nature.
