In a  bond, two or more nonmetals share a pair of   so that each element has a full valence shell. When a metal  one or more electrons and a nonmetal  those electrons, two -charged ions are formed which then bond to each other with an  bond. A  bond occurs between the atoms of a single metal element in which the metal's nuclei are surrounded by a "sea" of delocalized (free-moving) electrons. This type of bond is the structural reason for why metals have the property of being ​​​​​​​ of heat and electricity.

Metallic bonding always occurs between:Noble gasesMetal atomsNon-metal atomsMetal and non-metal atoms2A metallic bond is the electrostatic attraction between:Positive ions and delocalised electronsNegative ions and delocalised electronsElectrons and delocalised negative ionsElectrons and delocalised positive ions3Which of these is a property of metals?Poor conductors of electricityLow boiling pointsMalleableLow melting points4Which of the following statements best describes why metals are good conductors of heat?Metallic bonds are very strongLayers of metal atoms can slide past one another easilyMetals have high melting pointsThe delocalised electrons can carry thermal energy through the substance5Which of the following is a metal alloy?AluminiumCopperSteelIron6Metal alloys are generally harder and stronger than the individual elements they are made from. This is because the atoms of each element are of a different size and therefore:Disrupt the regular layers of ions, making them less malleableIncrease the size of the latticeLead to an increase in boiling pointLead to an decrease in boiling point

Which of the following statements is false about the structure and bonding in metals?The strong metallic bond is due to the sharing of the delocalised electrons between positive metal ions.There is an electrostatic attraction between the delocalised electrons and metal ions.Atoms in metals are arranged in an irregular pattern.The delocalised electrons can move freely throughout the structure.
