define metallic bond in 20 to 30 words
Answers
Answer:
metallic bond is a chemical bond in which electrons are shared over many nuclei and electronic conduction occurs.
Answer:
If you have already learned about covalent and ionic bonding, you know that these bonds occur between two atoms. When two atoms share electrons, they form a covalent bond. When one atom takes an electron away from another and the resulting positive and negative ions are attracted to each other, those atoms have formed an ionic bond.
A metallic bond is pretty different from covalent and ionic bonds, but the goal is the same: to achieve a lower energy state. Instead of a bond between just two atoms, a metallic bond is a sharing of electrons between many atoms of a metal element.
Take a look at your desk and see if you can find a small piece of metal like a paper clip or a staple. All of the atoms in that small piece of metal are sharing a big pool of valence electrons known as a sea of electrons or delocalized electrons. The big pool is like a free-for-all in that any valence electron can move to any atom within the material.
