Is caco3 an ionic or covalent compound?
Ionic bonding is a type of chemical bond that involves the electrostatic attraction between oppositely charged ions, and is the primary interaction occurring in ionic compounds.
The ions are atoms that have gained one or more electrons (known as anions, which are negatively charged) and atoms that have lost one or more electrons (known as cations, which are positively charged). A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms.
Pure copper, or any pure metal for that matter, normally form/are examples of metallic bonds, which are neither ionic nor covalent. What happens is, all the metal atoms release their valence electrons and thus have a full outer shell. However, this also makes them positive ions in a “sea of electrons”.
The bond between the copper and carbonate is ionic since the copper is positive (cation) and the carbonate is negative (anion) therefore the two opposing charges are attracted to each other. Carbonate is a polyatomic ion though therefore having a covalent bond. Therefore there is a covalent and ionic bond within Copper Carbonate.
Calcium carbonate is a chemical compound with the formula CaCO3 formed by three main elements: carbon, oxygen, and calcium.
Copper can change/bond to other metals with the exchange of electrons. Elements are constantly forming covalent bonds between other elemental atoms (when an element may share electrons with other atom) or losing electrons to become positively charged. However, copper is unique as it can form two ionic bonds.
Copper dichloride
Copper(II) chloride
Copper(II) chloride/IUPAC ID
CuI is an ionic compound that has each molecule made from one atom of copper (Cu) and one atom of iodine (I). The copper atom is positively charged and the iodine is negatively charged, so there is an ionic bond between them.
Calcium carbonate
Calcium carbonate/IUPAC ID
Calcium carbonate (CaCO3) is essentially an ionic compound with divalent calcium and carbonate ions. But the carbonate anion is a polyatomic species. The carbon atom is bonded to the three oxygen atoms by covalent bonds, two single carbon-oxygen bonds and a carbon dioxide double bond.
Calcium carbonate (CaCO3) has ionic bonding between calcium ion Ca2+ and a polyatomic ion, CO2−3, but within the carbonate ion (CO32-), the carbon and oxygen atoms are connected by covalent bonds (shown above).
