Subsequently, why is 3rd shell 8 or 18?
Originally Answered: According to the 2-8–8 rule, the 3rd orbital has only 8 electrons in its valence orbital, but from the formula 2n^2, the 3rd shell would have 18 electrons in its valence orbital.
Why does calcium only have 8 electrons in the third shell?
This principle states that, “Electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels. In this way, the electrons of an atom or ion form the most stable electron configuration possible.” … This is the reason for Calcium to have a configuration of 2,8,8,2 instead of 2,8,10.

Is the smallest unit that matter can be broken down into?
Atom, smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element. As such, the atom is the basic building block of chemistry.
What is the difference between Shell Subshell and Orbital?
The main difference between shell subshell and orbital is that shells are composed of electrons that share the same principal quantum number and subshells are composed of electrons that share the same angular momentum quantum number whereas orbitals are composed of electrons that are in the same energy level but have …
Why is lead pb2+?
Elements that haven’t got a very tight grip on these valence electrons, will lose their valence electrons. … Elements with more metallic properties (such as lead) will mostly form ionic bonds and elements with more non-metallic properties (such as carbon) will mostly form covalent bonds.
Which orbitals have the highest energy?
In all the chemistry of the transition elements, the 4s orbital behaves as the outermost, highest energy orbital.
Why does the third period have 8 elements?
The third period contains only eight elements even though the electron capacity of the third shell is 18 because when the other shells get filled and the resultant number of electrons becomes eighteen, it gets added up and settles in the third electron shell and three shells are acquired by the fourth period.
Why outermost shell Cannot have more than 8 electrons?
The shells of an atom cannot accommodate more than 8 electrons, even if it has a capacity to accommodate more electrons. … According to this rule, atoms gain, loose or share electrons to achieve the stable configuration similar to the nearest noble gas.
