Write a sentence that describes the purpose of the periodic table?
The elements of the periodic table are arranged in groups and periods. All of the elements in a period have the same number of atomic orbitals where as in a group all the elements have the same number of valence electrons.
Which element in the periodic table has 2 pairs of electrons in the 3d orbitals?
Silica has 2 pairs of electrons in the third orbitals. Atomic number of silica is 14. Electron configuration of it is, [Si]= 1s2 2s2 2p6 3s2 3p2 .
Elements on the right side of the periodic table with electrons sequentially filling the p orbitals of there valence shells are collectively known as the?
p-block
Why does the middle part of the periodic table doesn't have any valency?
Because the highest level of electron orbitals inhabited by the elements in the middle of the periodic table are not the farthest away from the nucleus, so their valence electrons are always present.
Do atom orbitals contain thousands of electrons or just a few electron?
If you look at a periodic chart, you will see that each element has a number. That number gives the number of protons and electrons that each element contains. There are limits to the number of electrons that any orbital can contain. The orbitals are labeled: s, p, d, f, g, h, i, k. The first two atoms in the periodic table, Hydrogen and Helium, only have an s orbital. The s orbital holds two electrons. When the s orbital is full, as with Helium, it can not react with anything else. Helium is inert. The next row in the periodic table contains the p orbital. When the p orbital is full, as in Neon, then it can not react. If you look at the periodic table, the orbitals can hold more electrons and each element can hold more orbitals. If it becomes possible to create an element with several hundred protons, the orbitals could hold many electrons.
What is the name of the collection of elements on the right side of the periodic table with electrons sequentially filling orbitals in their valence?
What is the name of the collection of elements on the right side of the periodic table with electrons sequentially filling orbitals in their valence?
How do you tell what elements in the periodic table have the same number of electrons in their outer orbitals?
They are in the same column.
Fourth period in periodic table?
This comprises all elements which have one or more electrons in their fourth shell. They comprise the fourth row of the periodic table.
What are electrons orbitals?
Orbitals are the paths of electrons that they make, forced through opposing charges in the nucleus. Orbitals in the sense that humans use them in organizational charts and diagrams involve the theoretical placement of such electrons in order to determine an atom's properties in placement among columns in the Periodic Table, it's bonding properties, it's possibilities of polarity and in order to "sort" electrons in the atomic model, which has been developed over periods of time. A column on the Periodic Table defines number of valence (very outer ring) electrons, and the row is sorted by number of orbitals, illustrating how important a knowledge of orbitals is to the understanding of an element.

What are the 4 main groups on the periodic table?
S block elements- valence electrons are filling the s orbitals D block elements- valence electrons are filling the d orbitals P block elements- valence electrons are filling the p orbitals F block elements- valence electrons are filling the f orbitals
What best describes why krypton is located in the last column on the periodic table?
Krypton is a noble gas. It has 8 electrons in the outermost shell. So it is in the last column of the periodic table.
Why are the lanthanides and actinides placed in the periodic table and why?
The lanthanides are elements 57-71 and are inserted after barium (Ba) on the periodic table. The actinides are elements 89-103 and are inserted after radium (Ra) on the periodic table. The reason they are there is because of the filling of electron orbitals in the atoms of the elements. There are four known orbitals, the s, p, d, and f orbitals. The lanthanide and actinide blocks are the result of electrons being inserted into the f orbitals.
