In 2004, 5-dehydro-m-xylylene (DMX) was the first reprted organic molecule known to violate Hund's rule.
It what happens when elements don't obey the octect rule, i.e. elements that have more than eight electrons in their outermost shell. It what happens when elements don't obey the octect rule, i.e. elements that have more than eight electrons in their outermost shell.
Elements with atomic numbers higher than 10 generally do not have 8 electrons in their outermost energy level. These elements tend to follow the octet rule, where they aim to have 8 electrons in their outer shell to achieve stability. Exceptions include elements such as transition metals that can have variable oxidation states.
Elements in the third period or below on the periodic table, such as sulfur, phosphorus, and chlorine, do not always follow the octet rule because they can accommodate more than eight electrons in their valence shell due to the availability of d-orbitals for bonding. Additionally, elements like boron and beryllium can form stable compounds with fewer than eight electrons.
To draw Lewis dot structures for elements, determine the total number of valence electrons for the element. Then, place the electrons around the element symbol in pairs, following the octet rule (except for hydrogen and helium, which follow the duet rule). Remember to show all valence electrons and distribute them evenly around the element symbol.
most metals do not follow the octet rule. when an atom has access to the D orbitals it usually follows the 18-electron rule (transition metals). non transition or F block elements usually contain a d orbital (when present) that is below the s and p orbitals in energy and do not usually use D electrons in bonding.

The octet rule is a rule in chemistry where elements want to form bonds to attain 8 electrons in their valence shell. An example of this would be sodium chloride. Bonds that don't have 8 electrons in their valence shell don't follow this rule
You probably mean the octet rule, which states that atoms undergo chemical bonding in order to achieve an octet (8) of electrons in their valence shell. This makes them stable. All of the main group elements follow this rule, except for hydrogen. It is stable with two valence electrons. The main group elements are Groups 1, 2, and 13-18.
* The roster process of math is the list or diagram of the ordered elements, when the rule is the equivalent form which will be using the choice of elements from a domain matching a rule. * The Roster process is one of four ways of representing that the elements of a set using brackets, {}.For example, all even numbers under 16 would be represented as : {2,4,6,8,10,12,14}. * The roster process is often associated with 'roster & rule' this is a way of finding a rule that the elements of a set follow. Sets can be usually comprise any list of items or numbered lists.
yes they do follow the rule of law.

Hund's Rule states that within a sublevel, electrons will fill empty orbitals before pairing up. This is to maximize the spin of the electrons and stabilize the atom. It helps to explain the arrangement of electrons in an atom's electron cloud.

the definition of rule in math is what step you need to answer a question. what should you do to answer a problem.....you have to follow the rule to able to answer a problem..for example :-to find the area of a circle. you have to follow the formula of the circle . which is A= radius square pi. if u follow the rule your answer will be correct.....
