Question

What are ionic compounds? Explain the formation of MgCl2? Explain with reason
four properties of these compounds?
​

Answer 1

Answer:

Compounds that consist of ions are known as ionic atoms. Atoms that gain or lose electrons are called ions, ions may have a negative charge or positive charge. Nonmetals lose electrons to gain negative charge and form anions, whereas metals lose electrons to gain positive charge and form cations. Anions are ions that have negative charge and cations are ions that tend to have a positive charge. Ionic bonds are generally between metals and non-metals.

For e.g. Salt (NaCl) is an ionic bond that consists of Sodium (Na) which is a metal with positive charge combines with Chlorine (Cl), a nonmetal with a negative charge. Another example of an ionic bond is Magnesium Hydroxide Mg(OH)2 which a combination of Magnesium (Mg) and Hydroxide (OH). Here, Magnesium is a metal with cations and Hydroxide is a nonmetal with anions. Iron Oxide (Fe2O3) also known as rust is also an ionic bond, it has metallic compound Iron (Fe) which contains positively charged cations and it has nonmetallic compound Oxygen (O) which contains negatively charged anions.
