Structure and bonding - Additional Science (Ionic bonding)

HideShow resource information
What is a compound?
Substances which atoms of two or more elements are chemically combined.
1 of 7
What are the two types of chemical bonding?
Transferring (Ionic) or sharing electrons (Covalent) .
2 of 7
What is ionic bonding? And why do atoms do this?
When metals and non-metals bond by giving/taking electrons. They do this to achieve a noble gas configuration.
3 of 7
When atoms form chemical bonds by transferring electrons what do they form?
Ions are formed. Atoms that LOSE electrons become POSITIVELY CHARGED ions. Atoms that GAIN electrons become NEGATIVELY CHARGED IONS.
4 of 7
How is an ionic compound formed?
When positive ions combine with negative ions.
5 of 7
What is the overall charge of an ionic compound?
0 (Zero)

What main features can we say about Sodium Chloride?
Giant structure of ions, held together by strong electrostatic forces of attraction between oppositely charged ions. These forces act in all directions in the lattice.
