What is a metallic compound?

Back

A metallic compound is a type of chemical compound that consists of metal atoms bonded together, typically exhibiting properties such as electrical conductivity, malleability, and ductility.

Front

What is a covalent compound?

Back

A covalent compound is formed when two or more non-metal atoms share electrons, resulting in a stable molecule. Examples include water (H2O) and methane (CH4).

Front

What is an ionic compound?

Back

An ionic compound is formed when electrons are transferred from one atom to another, resulting in the formation of positively and negatively charged ions that attract each other. Examples include sodium chloride (NaCl).

Front

How do you identify a metallic compound?

Back

Metallic compounds are typically solid at room temperature, have high melting points, and conduct electricity in solid and liquid states.

Front

How do you identify a covalent compound?

Back

Covalent compounds usually have lower melting and boiling points compared to ionic compounds and do not conduct electricity in any state.

Front

How do you identify an ionic compound?

Back

Ionic compounds are usually solid at room temperature, have high melting and boiling points, and conduct electricity when dissolved in water or melted.

Front

What happens during the formation of an ionic bond?

Back

During the formation of an ionic bond, one atom donates an electron to another atom, resulting in the formation of ions that are held together by electrostatic forces.

Front

What is the significance of electron transfer in ionic bonding?

Back

Electron transfer is crucial in ionic bonding as it leads to the formation of charged ions, which create strong attractions between oppositely charged ions.

Front

What is the difference between covalent and ionic bonds?

Back

Covalent bonds involve the sharing of electrons between atoms, while ionic bonds involve the transfer of electrons from one atom to another.

Front

What is a common property of covalent compounds?

Back

Covalent compounds often have lower melting and boiling points compared to ionic compounds and may exist as gases, liquids, or solids.
