Metallic Bonding Flashcards
What is metallic bonding?
Metallic bonding involves delocalised electrons and strong electrostatic attraction between positive metal ions and shared negative electrons.
What is the structure of metals?
Metals consist of a giant structure.
What are delocalised electrons?
Delocalised electrons are electrons in the outer shell of metal atoms that are free to move around.
What holds the atoms together in metallic bonding?
Strong forces of electrostatic attraction between positive metal ions and delocalised electrons.
What types of substances are held together by metallic bonding?
Metallic elements and alloys.
What physical property of metals is due to delocalised electrons?
The properties of metals, including conductivity and malleability.
What energy is required to break the electrostatic forces in metals?
A lot of energy is required due to the strong electrostatic forces.
What are the melting and boiling points of compounds with metallic bonds?
They generally have very high melting and boiling points.
What state are most metals at room temperature?
Most metals are shiny solids at room temperature.
Are metals soluble in water?
No, metals are generally not soluble in water.
How does the density of metals compare to non-metals?
Metals are generally more dense than non-metals.
What property allows metals to be malleable?
The layers of atoms in a pure metal can slide over each other.
What makes metals good conductors of electricity and heat?
The delocalised electrons carry electrical charge and thermal energy.
What causes non-metals to have different physical properties than metals?
Non-metals do not have metallic bonding.
What are some characteristics of non-metals?
Dull looking, more brittle, lower boiling points, generally not solid at room temperature.
How do non-metals conduct electricity?
Non-metals do not generally conduct electricity unless dissolved in water.
What is the electron behavior of non-metals in chemical reactions?
Non-metals tend to gain electrons to form full outer shells.
What is the electron behavior of metals in chemical reactions?
Metals lose electrons to gain full outer shells.
