Name two compounds that are covelent when taken pure but produce ions when dissolved in water.
Ammonia and HCL
What do you mean by valence shell ?
The outermost shell of an atom is called Valence Shell.
What is Triple bond ?
The bond is formed by the sharing of three pairs of electrons between two atoms .
What is Double Bond ?
The bond is formed by the sharing of two pairs of electrons between two atoms.
What is single Covalent bond ?
The bond is formed by the sharing of one pair of electrons between the atoms, each atom contributing one electron.
What is Covalent compound ?
The compound formed due to covalent bond is called Covalent compound.
What is Covalent bond ?
The chemical bond that is formed between two combining atoms by mutual sharing of one or more pairs of electrons is called Covalent bond.
Why are Ionic Compounds Stable ?
Ionic compounds are formed by ions but there also exists a repulsive force between ions for like charges. Since the electrostatic force of attraction between opposite charges is much higher, it makes the ionic compounds stable.
What do you mean by Electrovalency ?
The number of electrons that an atom of an element loses or gains to form an electrovalent bond is called its Electrovalency.
What are Electrovalent bond ?
The cation and the anion being oppositely charged attract each other and form a chemical bond. Since this chemical bond formation is due to the electrostatic force of attraction between a cation and anion, it is called an Electrovalent bond.
