Chapter 14.2 Flashcards
What are the attractive forces that link the two or more atoms that molecules and compounds are composed of?
Chemical bonds
What is a chemical bond resulting from the sharing of electrons between atoms?
Covalent bond
What type of bond occurs when two atoms share a single pair of electrons?
Single bond
What is it called when atoms share two pairs of electrons?
Double bond
What type of bond occurs when atoms share three pairs of electrons?
Triple bond
What is a diagram showing the locations of all the atoms and valence electrons?
Lewis structure
What describes how strongly atoms of that element pull on electrons in chemical bonds?
Electronegativity
What type of bond forms when one of the atoms has a greater electronegativity than the other atom?
Polar bond
What is a charge less than that of a proton or electron?
Partial charge
What has opposite partial charges on opposite ends of the molecule?
Polar molecule
What consist of atoms covalently bonded into large structures that do not contain a specific number of atoms?
Covalent networks
What is the simplest ratio of atoms in a covalent network?
Formula unit
What is the mass of a formula unit?
Formula mass
What are atoms that gain electrons?
Anions
What typically form between a metal and nonmetal?
Ionic bond
What is an ion formed from a group of atoms?
Polyatomic ion
What consist of millions or billions of ions all bonded by electrical attraction?
Ionic crystals
What is a unique type of bonding because the valence electrons are shared by all the atoms in the metal?
Metallic bonding
What are combinations of chemical symbols and numbers showing the type and number of atoms in each compound?
Chemical formulas
What tells how many of each type of atom are in a molecule?
Molecular formula
What shows the general arrangement of the atoms in a molecule?
Structural formula
What shows only the simplest ratio of atoms in a compound?
Empirical formula
