Which type of bond is the strongest?
Covalent
Which property of an ionic compound means that the compound can dissolve in water?
What is a covalent bond?
A bond formed by the sharing of electrons.
What is a metallic bond?
Forms between metal atoms when their outermost energy levels overlap.
A water molecule is formed by what kind of bond?
Which type of bond is made from an attraction between a positively and negatively charge particle?
Ionic Bond
What type of structure does an ionic compound have?
Crystal lattice structure
When atoms join together with covalent bonds, they form.....
Molecules
Are metallic compounds good conductors of electricity?
Yes, because the electrons move freely
Describe the movement of electrons in a metal.
Electrons move freely throughout the metal.
Which type of bond is made by an overlap in the outermost energy level?
Metallic Bond
What does brittleness mean?
More likely to break than bend. Easily broken.
Why do covalent compounds have low melting and boiling points?
Unlike ionic compounds, the bonds in a covalent compound do not break easily. However, the molecules separate easily, causing low melting and boiling point.
What is malleability?
The ability of a metal to be hammered into sheets.
Water molecules attracting the positive and negative salt ions.
Which kind of bond makes a crystal lattice structure?
Ionic Bond
Explain the electrical conductivity of ionic compounds in solid and liquid forms.
Solid ionic compounds are poor conductors. Melted ionic compounds as well as ionic compounds dissolved in water can conduct electricity.
Are covalent compounds good conductors of electricity?
No, they are poor conductors.
What is ductility?
The ability to be formed into long thin wires.
How does a positive ion form?
By losing an electron.
