PPT-Polar Covalent

B onds Polar bond A type of covalent bond between two atoms in which electrons are shared unequally resulting in a bond in which one atom has a slightly negative charge and the other a slightly positive charge. Co = Together. The Octet Rule. The octet rule says that all atoms want to have eight valence electrons, like the noble gases.. One way that atoms can follow the octet rule is by giving and taking electrons… ionic bonding. What is the arrangement of the electrons around each chlorine atom in Cl. 2. ?. 2, 8, 8. This is the same as the electron configuration of an atom of which noble gas?. Argon. When atoms bond . covalently. Chapter 9 ~ most compounds, including those in living organisms, are covalently bonded. What You’ll Learn. I will analyze the nature of a covalent bond. I will name covalently bonded groups of atoms. COVALENT BOND. bond. formed by the . sharing . of . electrons . Covalent . Bonds. Between nonmetallic elements of similar electronegativity. .. Electronegativity = how badly an atom wants to add an electron (non metals have higher electronegativity). This topic will be investigated under five main headings:. Chemical Compounds. .

Each has its own strengths and limitations.. Ga . Standards. Students know . atoms combine to form molecules by sharing electrons to form covalent or metallic bonds or by exchanging electrons to form ionic bonds.. Polarity and Electronegativity. Think about it. What does the word POLAR mean to you?. Polar Bear North/South Poles. Polar Molecules. What is Electronegativity?. Electronegativity:. .
