VI - CORRECT ANSWER A A 55-year-old woman has been referred for a psychiatric evaluation for a change in personality, lack of impulse control, and increasingly reckless decision-making....

Molecule Unit of matter that results when two or more atoms are joined by covalent bonds Ionic Bond A bond resulting from the electrostatic attraction of a cation for an anion. Brainpower Read More Nonpolar Covalent Bond A bond characterized by an even distribution of charge; electrons in the bonds are shared equally by the two atoms Polar Covalent Bond A bond resulting from unequal sharing of bonding pairs of electrons between atoms Polyatomic Ions Charged g...

covalent bonds form based on Ans:the sharing of electrons that provides an octet of electrons for each most energetically stable elements in the periodic table Ans:noble gases noble gases are also referred to as Ans:inert gases octet rule Ans:all atoms should strive to have 8 electrons in their outermost shell to achieve the most energetically stable state valence electrons Ans:electrons found in the highest energy shell of an atom (aka the highest principle quantum number, n, shell...

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. ...

CHEM 120 Final Exam | Questions and Correct Answers | Latest Update 2024/2025 | 100% Pass B - Answer -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. C - Answer -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 li...

Covalent bonds: Covalent compounds are formed when nonmetals share valence electrons forming a covalent bond. Ionic bonds: Ionic compounds are formed when metal atoms transfer electrons to nonmetal atoms resulting in the formation of ionic bonds. Covalent bond: Share electrons with nonmetal to form a covalent bond Ionic bond: transfer electrons from metal to nonmetal to form covalent bond - electron donor and an electron acceptor (cation and anion) Covalent: water, H2O 2 H atoms + 1 O ato...

Lewis Structures - represents the transfer or the sharing of electrons in chemical bonds octet rule - EVERY ATOM WANTS 8 ELECTRONS IN THEIR OUTERSHELL ionic bonding - chemical bond formed through the transfer of one or more electrons from one atom or group of atoms to another group EX : NaBr metals - give nonmetals - take oxidation number - the superscript indicating the charge on an ion ion - atom with either positive or negative charge binary compound - compounds in which 2 elements a...

Gaining vs. Losing electrons - ️️N+1 = Losing electron N-1 = Gaining electron Electrons = electronegative Octet rule - ️️Atoms are most stable when their outer shell is full. The outer shell has to be filled with 8 electrons EXCEPT Hydrogen and Helium with just 2 electrons. Three Physical States of Matter - ️️Solid, liquid, gas Element - ️️Substance that cannot be broken down into other substances by chemical reactions Matter - ️️Anything that occupies space and has a...
