In (a) sodium oxide was answered better than phosphorus(V) oxide (a direct reference to Assessment Statement 13.1.1) although there were many instances of NaO. The formula for diphosphorus trioxide is P2 O3. Therefore, the electrons are SHARED, as they are in ALL bonds. 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). CaPO 4. Strong covalent bonds were in situ constructed in a unique black phosphorus (BP) @ reduced graphene oxide nanocomposite via a facile and scalable high energy ball-milling process, which contributes to the high specific capacity of BP@irGO and tackles the long-standing problem of large volume expansion of high capacity electrode matrerials.

A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. The bond character is polar covalent although the difference is very close to that of ionic bonds. 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. Fe(III)Br.

In (b) there were the usual suggestions that covalent bonds are weaker than ionic bonds. Phosphorous chlorides. Whereas ionic compounds are usually formed when a metal and a nonmetal combine, covalent compounds are usually formed by a combination of nonmetals. Ca 3 PO 4. 34 Ionic and Covalent Structure Ionic compounds Water H atoms lattice - a repeating O atom Covalent compounds B+3 ions form individual N-3 ions molecules that are not connected to Boron nitride each other.
