Question

question 19 of 20 identify the type of bonding within each substance. co(s) ionic metallic covalent cocl₂(s) metallic covalent ionic ccl₄(l) metallic ionic covalent

Explanation:

1. For Co(s) (cobalt in solid - state), metals like cobalt have metallic bonding. In metallic bonding, metal atoms release their outer - shell electrons to form a sea of delocalized electrons, and the metal cations are held together by the electrostatic attraction to these electrons.
2. For CoCl₂(s) (cobalt(II) chloride in solid - state), it is an ionic compound. Ionic bonding occurs between a metal (cobalt) and non - metals (chlorine). Cobalt donates electrons to chlorine atoms, forming positively charged cobalt ions and negatively charged chloride ions, which are held together by electrostatic forces.
3. For CCl₄(l) (carbon tetrachloride in liquid - state), it is a covalent compound. Covalent bonding occurs when non - metal atoms (carbon and chlorine) share electrons to achieve a stable electron configuration.

Answer:

Co(s): B. metallic
CoCl₂(s): C. ionic
CCl₄(l): C. covalent
