Answer: Read through this, hope It helps
Explanation:
Covalent bonds are formed when nonmetals form compounds with each other by sharing electrons between them.
Ionic bonds are formed when one ion — an atom or molecule with a net charge, either positive or negative — finds another ion of the opposite charge to bond with, creating an overall neutral ionic compound.
Answer:
The volume will remain the same.
Explanation:
The volume of a given gas sample is directly proportional to its absolute temperature at constant pressure (Charles's law)
Metallic bonds result when electrons are shared equally.
