Chapter 3 Test 3.1 Flashcards
Chemical bond
Links between two or more atoms that hold the atoms together, they are formed when atoms gain or lose electrons or when they share electrons
Covalent compounds
Compounds such as water in which two atoms share a pair of electrons, combine to form molecules.
Bound together by sharing one or more pair of electrons. If atoms share electrons then there cove lent. Form when non-metals atoms bond together by sharing there electrons
Ionic compounds
Compounds such as table salt, in which oppositely charged ions come together because of mutual attraction. Atoms gain or lose electrons to form ions. They form between Metals and non- metals
Polyotomic compounds
Compound that contains one or more atoms. A molecular ion composed of more then one type of atom joined by covenant bonds. “Poly” means many. Ones with 3 elements in a formula, a combonation. Some molecules gain and lose one or more electrons as their atoms combine to form a molecule, when doing this they become a molecular ion

Sodium chloride
Example of : polyotomic compound
Many common ones, one kind is carbonate CO3,2- helps form a delicate shell of a robins egg, hydroxide cation - OH1
What is an Ionic Lattice
Repeating pattern of positive and negative ions forming an ionic compound. Often used in the ionic compound
