You will have the opportunity to earn two test grades for chapter 5. Fist opportunity will be anormal test. Second will be a group project Ionic and Covalent Bond Poster and Model Project.
Test 1 Study Guide is listed below download it to complete it for a grade. Also listed below are fact on Ioinc vs. Covalent Bonds. You should be able to complare and contrast the two types of componds and the way they bond.
The number of valence electrons in an atom of an element determines many properties of that element, including the ways in which the atom can bond with other atoms.
The periodic table gives you information about the arrangement of electrons in atoms.
The elements within a group have similar properties because they all have the same number of valence electrons in their atoms.
When an atom loses an electron, it becomes a positive ion. When an atom gains an electron, it becomes a negative ion.
Ionic bonds form as a result of the attraction between positive and negative ions.
When ionic compounds form, the charges on the ions balance out.
Ionic Bond Animation from class:
The force that holds atoms together in a covalent bond is the attraction of each atom’s nucleus for the shared pair of electrons.
Atoms can share 1 pair of electrons in a double bond, 2 pairs of electrons in a double, and 3 pairs in a triple
