The tendency of some atoms to have 8 electrons in their outermost shell (two e- in the S orbital and six e- in the P orbital) is called the "octet rule."

What is the same within each group on the periodic table?
Numbers and arrangements of electrons in their outermost shells.
Do all alkaline metals have 2 electron shells?
No. All the alkaline earth metals have 2 valence electrons, meaning they have two electrons in the outermost shells. No two alkaline earth metals have the same number of electron shells. Beryllium is the only one with two shells.
How many electrons does phosphorus have in its penultimate shell?
If "penultimate" means "next-to-outermost", the correct answer is 8: The innermost shell is full with two 1s electrons; the next-to-outermost shell is full with two 2s electrons and six 2p electrons, for a total of 8. The outermost shell has five valence electrons, constituting with the two inner shells the remainder of the proper number of total electrons for phosphorus, 15, its atomic number.
Why is fluorine a fairly reactive element while helium is not?
because helium has a full outermost shell, which has a capacity of 2 electrons whereas fluorine has 2 shells, the outermost having a capacity of 8 electrons and has, by nature, only 7 electrons. elements in general, atleast up to the 20th element, the first shell has a capacity of 2 electrons, the 2nd shell has a capacity of 8 electrons, the third has a capacity of 8 electrons. also there are elements that are not reactive and are known as the noble gasses. these are helium, neon, argon, xenon, etc and are known as the noble gasses. these elements which happen to be present in the form of gasses has full outermost shells, that is if the outermost shell has a capacity of 2electrons then it actually has, by nature, 2 electrons in it, and if it has a capacity of 8 electrons, then it has 8 electrons in it and so on. hence non reactive because there is no 'free' electrons or space to hold 'extra' electrons.
How many electrons does francium have in its outer most shell?
francium only has one valence electron (one electron in the outermost shell).
Which elements can lose electrons from the two outermost shells?
All thed block elements (except d10) have this tendency.
Noble gases are very stable because their outermost electron shells contain the maximum number of electrons that those outermost shells can possess?
Noble gases are very stable because their outermost electron shells contain the maximum number of electrons that those outermost shells can possess. This is a correct statement. Yes.
Why are Neon and Argon such nonreactive elements in the periodic table?
Neon (atomic number 10) and Argon (atomic number 18) mostly do not react with other elements because their outermost electron shells have a full complement of electrons. When two elements combine into a molecule they share electrons from their outermost electron shell. This happens when one element has a minimal number of electrons in its outer shell and the other element has an almost full complement of electrons in its outer shell. When they share electrons, they both have the equivalent of full outer electron shells. Since both Neon and Argon have full outermost shells by themselves they do not have a tendency to share electrons.
Where would you find valence electrons?
They are the electrons in the outermost shell, and are the ones involved in most chemical reactions.
Noble gases have how many electrons in their outer shells?
They have 8 electrons on the outermost shell, also known as valence.
Are all the electrons in atoms used in bonding?
No, except for hydrogen. Bonding uses outermost electrons (outside full shells).
What is the number of valence electrons in selenium?
Selenium has 6 electrons in its outermost shell.
Do atoms with many electron shells let go of their electrons easier than fewer shells?
More the number of shells in an atom, more away will be the electrons from the nucleus. Hence, weaker will be the attraction between nucleus and outermost electrons. So atom with more shells will let go their electrons easier than atoms with fewer shells.
How is the noble gas element helium differ from radon?
Helium has 2 electrons and Radon has 86 electrons but both have 8 valence electrons (8 electrons in their outermost shells)
Why do the atoms of a noble gas not combine to from diatomic or large molecules?
Because the outermost layer of the shells of the noble gases is filled with the maximum number of electrons - 2 electrons into the s block (s orbital) and 6 electrons into the p block (per 2 in py, px, and pz orbitals).
What is different in number of shells in magnesium and sulphur?
There are no difference in the number of shells in magnesium and sulphur. Both elements contain 3 shells. However, the total number of electrons in the shells are different. Magnesium has 12 electrons in its shells whereas sulphur has 16 electrons in its shell. In addition, the electrons in the valence shell (outermost shell) are also different. Magnesium has 2 electrons in its valence shell whereas sulphur has 6 electrons in its valence shell.
What is the same within each group on the periodic table?
