Octet rule Study guides, Class notes & Summaries

How many bonds can nitrogen have? Which rule or principle should be used? A) Five bonds; octet rule. B) Three bonds; octet rule. C) Three bonds; the Hund's rule. D) Five bonds; the Aufbau Principle. correct answer: B When two hydrogen atoms meet, they will attract to each other and form a bond (and a H2 molecule). Why? A) Because electrons like to stay together. B) Because electrons like to be paired up. C) Because there is attraction between the electron in one hydrogen atom an...

Describe the atomic differences between Ionic and Covalent bonds. 1. Ionic bonds form between ions and involve gain or loss of electrons, while covalent bonds occur when electrons are shared between two atoms What is the octet rule? List three types of elements that do not follow the octet rule and explain why. Octet rule=atoms tend to bond with other atoms so they have eight outer electrons in their valence shell 1. Elements with incomplete octets, includes: H, He, Li, Be, and B. 2. ...

Anatomy - Study of body structure Physiology - Study of function How are anatomy and physiology related? - structure determines what functions can take place Specialties in the study of anatomy - Macroscopic and microscopic Specialties in the study of physiology - Cell, special (specific organs), systemic (organ systems), and pathology (disease) Homeostasis - process by which organisms maintain a relatively stable internal environment components of homeostasis - stimulus, recep...

ATI TEAS 7 Test Chemistry - Chemical Bonds & Solutions (Answered) valence electrons The number of valence electrons in an atom is the most important factor in determining how an element will react. Valence electrons, which are found in an atom’s outermost energy level, are involved in forming chemical bonds. octet rule The octet rule states that atoms will lose, gain, or share electrons to obtain a stable electron configuration of eight valence electrons. In other words, if an atom nee...

Lewis dot structure: steps Correct Answer 1. Find total # of valence electrons for all atoms in molecule 2. Use one pair of electrons to form one bond between each atom 3. Arrange remaining electrons around atoms to satisfy duet for H and octet for other atoms Exceptions to octet rule Correct Answer 1. B, Be: may have less than an octet 2. Atoms with an odd number of electrons 3. Atoms in the 3rd period or greater (with d orbitals available for hybridization) may have greater than an octe...
