Ionic bonding Flashcards
Atom
The smallest part of an element that can exist.
Ion
formed when atoms gain or lose electrons to form a full outer shell.
Electron
Electron shells
are arranged in different shells around the nucleus
Transfer
one electron goes to the other atom
Metal ions
can be found in aqueous solutions of metal compounds. will form positive ions when reacted
Non-metal ion
Non-metals will form negative ions when they react
ion bond
The metal atoms become positive ions and the non-metal atoms become negative ions. There is a strong electrostatic. force of attraction between these oppositely charged ions – this is called an ionic bond.
Electrostatic attraction
holds the two atoms in the covalent bond together.
High melting point
Ionic compounds have high melting and boiling points. The melting and boiling points of ionic compounds is usually quite high because the ions in the giant ionic lattices are held together by strong electrostatic forces of attraction which are difficult to overcome.
Soluble
dissolves to form sugar solution
Electrical conductors
Metals are good conductors of electricity because their delocalised electrons can carry a charge within the structure.
Molten
an element or compound that has been melted into a liquid form
In solution
forms when a solute. dissolves. in a solvent close solvent
