The further down the Periodic Table that you go the more electrons that an element has, also the more orbitals an element has. If you look up general trends in the periodic table ionic size is showen to increase too. The ionic size is directly related to these larger orbital shells that hold more electrons.
S orbital = 2 é
P orbital = 6é
D orbital = 10é
You may want to look up these orbitals to get a better understanding of them, each one has a unique shape http://en.wikipedia.org/wiki/Atomic_orbital
some atoms can exceed the octet rule by using these unfilled larger orbitals to put electrons into them, so for example they might use the D orbital to place extra electrons into it, causing the octet rule to break down.

∙ 14y agoafter the discovery of Transition metals the octet rule lost its significance but it still works for non metals except those atoms or ions which have only one electronic shell.

∙ 9y agoYes sulfur and phosphorus can expand the octet. They can have 12 or 10 valence electrons, respectively, when combined with small halogens. In PCl, phosphorus has 10 valence electrons.

What types of atoms undergo covalent bonding?
They are the atoms that want to obtain a complete shell either duplet or octet.
What is the magic number of electrons when you are bonding element?
For most atoms, it is 8 valence electrons, usually referred to as an octet.
What is the duet rule?
OCTET RULE:-The tendency of atoms to require eigth electron configuration in their valence shell, when bonding,is called octet rule.DUPLET RULE:-The tendency of atoms to require two electron configuration in their valence shell, when bonding,is called duplet rule
How are the duet and octet rules used to describe the arrangement of electrons in a molecule?
The very simple duet and octet models of covalent chemical bonding describe the chemical bond as involving an electron pair situated between atoms and that atoms lighter than He (there is only H!) achieve a stable duet (2 electrons)-- atoms heavier than He achieve an octet. the duet and octet are the stable configurations of noble gases. Lewis dot diagrams are typically used to "place" the electrons in the appropriate positions.
A molecule with bonding that follow the octet rule?
Boron And Berylium
What do atoms gain by chemically bonding?
Atoms gain stability by bonding. This is usually due to achieving a noble gas configuration, also called an octet, as a result of bonding.
What types of atoms undergo covalent bonding?
They are the atoms that want to obtain a complete shell either duplet or octet.
How many electrons must the atoms of S share with other atoms in covalent bonding to achieve an octet of electrons?
two electrons

What is the duet rule?
OCTET RULE:-The tendency of atoms to require eigth electron configuration in their valence shell, when bonding,is called octet rule.DUPLET RULE:-The tendency of atoms to require two electron configuration in their valence shell, when bonding,is called duplet rule
Atoms can achieve a full octet of electrons by doing what?
By bonding with another atom, either ionically (donates/receives electrons) or covalently (electron sharing).
In which bonding patterns does X obey the octet rule?
no it does not follow octet rule
What is the optimum number of electrons for phosphorous to possess in its outermost closed shell?
The optimum number of electrons in the outermost valence shell for phosphorus atoms is eight, known as an octet. Unbonded phosphorus atoms have 5 valence electrons and undergo chemical bonding in order to gain the other 3, either by covalent bonding or by ionic bonding.
What is covalent bonding like?
Covalent bonding is when 2 atoms, usually non-metals, bond together by sharing electrons with one another. For example, in oxygen gas, one oxygen atom will share 2 electrons with the other so that both atoms can achieve the octet structure.
How are the duet and octet rules used to describe the arrangement of electrons in a molecule?
The very simple duet and octet models of covalent chemical bonding describe the chemical bond as involving an electron pair situated between atoms and that atoms lighter than He (there is only H!) achieve a stable duet (2 electrons)-- atoms heavier than He achieve an octet. the duet and octet are the stable configurations of noble gases.

What are 3 atoms are exceptions to the octet rule?
Boron is one. It exceeds the octet rule.
