Section 1: Bonding Key Terms Flashcards
To understand the key terms for the topic and be able to use them in sentences.
Ion
A charged particle formed when atoms lose or gain electrons.
Ionic bond
An electrostatic attraction between two oppositely charged ions. (metal and non- metal)
Electrostatic attraction
The attraction between a negatively charged particle and a positively charged particle.
Metals
In ionic bonding, metals lose electrons to become positively charged ions.
Non - metals
In ionic bonding, non - metals gain electrons to become negatively charged ions. Located on the right hand side of the periodic table.
Giant lattice
A large regular 3D structure that contains millions of bonds.
Covalent bond
A bond formed when non - metals share electrons. An electrostatic attraction between the positively charged nuclei of the bonded atoms and the electrons shared between them.
Molecule
A small group of atoms held together with covalent bonds. Not charged.
Polymer
Very large covalently bonded molecules with many repeating units.
Metallic bonding
The bonding of metal consists of a lattice of positive ions surrounded by a sea of delocalised electrons. The metallic bond is the electrostatic attraction between the positive ions and the delocalised electrons.
Alloy
A mixture of two or more elements at least one of which is metal. Example: Steel is a mixture of iron and carbon.
