What type of bonding for zinc , Zn(s)
Type of bonding of zinc , Zn (s)
a. Zinc, Zn (s): The type of bonding in zinc is Zn(Technically it's a metal, so it forms metallic bonds. But let's pretend it's a comedian, so it bonds with laughter).
b. Propane, C3H8 (l): The type of bonding in propane is covalent bonding, where the carbon and hydrogen atoms share electrons like best buddies at a party.
c. Calcium Carbonate, CaCO3 (s): The type of bonding in calcium carbonate is ionic bonding. It's like a rock-solid relationship where calcium and carbonate ions are attracted to each other and stay together, not letting anything come between them.
To determine the type of bonding in each substance, we need to consider the types of elements present and their bonding patterns. Here's how we can analyze each substance:
a. Zinc, Zn (s):
Zinc is a metallic element, and in its solid state, it forms a metallic bond. Metallic bonding occurs when metal atoms lose their valence electrons and form a "sea" of delocalized electrons, which are free to move within the solid metal. This results in a lattice structure held together by the electrostatic interactions between the positive metal ions and the shared electrons.
b. Propane, C3H8 (l):
Propane is a hydrocarbon composed of carbon (C) and hydrogen (H) atoms. The bonding in propane is covalent. Covalent bonding occurs when atoms share electrons to form a stable electron configuration. In propane, each carbon atom forms four covalent bonds with surrounding hydrogen atoms, resulting in a stable molecule.
c. Calcium Carbonate, CaCO3 (s):
Calcium carbonate consists of calcium (Ca), carbon (C), and oxygen (O) atoms. The bonding in calcium carbonate is a combination of ionic and covalent bonding. The calcium atom donates two electrons to each of the oxygen atoms, resulting in the formation of Ca2+ ions and CO3 2- ions. The ionic bonds between the calcium and carbonate ions hold the structure together. Additionally, within the carbonate ion, the carbon and oxygen atoms are covalently bonded, sharing electrons to stabilize the ion.
In summary:
a. Zinc, Zn (s) - Metallic bonding
b. Propane, C3H8 (l) - Covalent bonding
c. Calcium Carbonate, CaCO3 (s) - Combination of ionic and covalent bonding
