Indicate the type of crystal (molecular, metallic, covalent-network, or ionic) each of the following would form upon solidification.
1. B
r2
2. Silicon dioxide
3. Sodium chloride
4. Copper
5. Water
1. Boron would likely form a covalent-network crystal.
2. Silicon dioxide forms a covalent-network crystal.
3. Sodium chloride forms an ionic crystal.
4. Copper forms a metallic crystal.
5. Water forms a molecular crystal (ice).
To determine the type of crystal that element B would form upon solidification, we need to analyze its bonding characteristics.
Element B is not specified, so let's assume it refers to a hypothetical element.
To determine the type of crystal formed, we need to evaluate the nature of the bonding between the atoms.
If element B forms metallic bonds, it would result in a metallic crystal. In metallic bonding, valence electrons are delocalized, forming a "sea" of electrons surrounding positively charged metal ions.
If element B forms covalent-network bonds, it would result in a covalent-network crystal. In a covalent network, atoms are held together by a network of covalent bonds forming an extended lattice structure.
If element B forms ionic bonds, it would result in an ionic crystal. In ionic bonding, valence electrons are transferred from one atom to another, resulting in the formation of positively charged ions (cations) and negatively charged ions (anions) that are held together by electrostatic forces.
If element B forms molecular bonds, it would result in a molecular crystal. In molecular bonding, atoms within a molecule are held together by covalent bonds, and intermolecular forces hold the individual molecules together in the solid state.
Without further information, we cannot definitively determine the type of crystal element B would form. We would need additional knowledge about its bonding characteristics or any specific information about the element.
