I need 23 and 24 Question 23Metals can be rolled into sheets and stampedinto various forms whereas diamond is veryhard. An explanation of these properties isthat:a) metals have covalent bonds whilediamond has ionic bonds in which electronsare transferred between neighbouringcarbon atoms.Ob) electrons surrounding a given metal atomare free to move throughout the metal whilein a diamond, the bonding electron pairs areheld tightly between two carbon atoms in atetrahedral pattern.c) electrons of metals are held more tightlyto the parent atoms that are electrons ofcarbon atoms, hence bonds in metals arealways stronger.Od) diamond has strong double bondsbetween carbon atoms while metal bondsare normal single covalent bonds whichbend easily.Question 24Which of these substances form solids heldtogether by primarily ionic forces ofattractions?helium, carbon tetrabromide, and ethanewater and ammoniasilicon dioxide and silicon carbideO sodium iodide and lithium hydroxide

Metals can be rolled into sheets and stamped into various forms whereas diamond is very hard. An explanation of these properties is that: a) metals have covalent bonds while diamond has ionic bonds in which electrons are transferred between neighbouring carbon atoms. Ob) electrons surrounding a given metal atom are free to move throughout the metal while in a diamond, the bonding electron pairs are held tightly between two carbon atoms in a tetrahedral pattern. Oc) electrons of metals are held more tightly to the parent atoms that are electrons of carbon atoms, hence bonds in metals are always stronger. Od) diamond has strong double bonds between carbon atoms while metal bonds are normal single covalent bonds which bend easily.
