Answer:
When a metal element reacts with a non-metal element an ionic compound is formed. An understanding of the way the elements are bonded allows us to explain their typical properties.
Reactions between metals and non-metals include:
sodium + chlorine → sodium chloride
magnesium + oxygen → magnesium oxide
calcium + chlorine → calcium chloride
Explanation:
In all of these reactions, the metal atoms give electrons to the non-metal atoms. The metal atoms become positive ions and the non-metal atoms become negative ions.
A metal atom often stop reacting when it has lost all of its outer electrons.
Metal atoms often have few electrons in their outer shell.
Non-metal atoms does have plenty of electrons in their outer shell.
A Metal atoms lose the electron, or electrons, when in their highest energy level and tend to be positively charged ions.
Non-metal atoms often gain an electron, or electrons, so as to be negatively charged ions.
The loss or gain of valence electrons make ions to work with the octet rule and become more stable.
