Answer: b. K and Br
In ionic bonding the atoms are bound by attraction of oppositely charged ions whereas in covalent bonding atoms are bound by sharing electrons to attain stable electron configurations. In covalent bonding the molecular geometry around each atom is determined by valence shell electron pair repulsion VSEPR rules whereas in ionic materials the geometry follows maximum packingrules. One could say that covalent bonding is more directional in the sense that the energy penalty for not adhering to the opt…
The resulting compound is called an ionic compound and is said to be held together by ionic bonding . In ionic compounds there arise characteristic distances between ion neighbours from which the spatial extension and the ionic radius of individual ions may be derived. The most common type of ionic bonding is seen in compounds of metals and …
In chemistry an ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding . The compound is neutral overall but consists of positively charged ions called cations and negatively charged ions called anions. These can be simple ions such as the sodium and chloride in sodium chloride or polyatomic species such as the ammonium and carbonate ions in ammonium carbonate. Individual ions within an ionic compound …

Strong chemical bonds are the intramolecular forces that hold atoms together in molecules. A strong chemical bond is formed from the transfer or sharing of electrons between atomic centers and relies on the electrostatic attraction between the protons in nuclei and the electrons in the orbitals. The types of strong bond differ due to the difference in electronegativity of the constituent elements. A large difference in electronega…
