Answer 2

Chemical Bonds in Various Substances

N2: The chemical bond in N2 is a triple covalent bond. Each nitrogen atom shares three electrons with the other, forming a very strong bond..

H2O: In H2O, the chemical bond is a covalent bond between the hydrogen and oxygen atoms. The oxygen atom shares electrons with the hydrogen atoms, creating a stable molecule..

PH3: In PH3, the chemical bond is a covalent bond. Phosphorus shares electrons with the hydrogen atoms, forming a stable molecule..

F2: The chemical bond in F2 is a single covalent bond. Each fluorine atom shares one electron with the other, creating a stable molecule..

KCl: In KCl, the chemical bond is an ionic bond. Potassium donates an electron to chlorine, resulting in the formation of a positively charged potassium ion and a negatively charged chloride ion, which are held together by electrostatic forces..

I2: The chemical bond in I2 is a covalent bond. The iodine atoms share electrons, forming a stable molecule..

H2S: In H2S, the chemical bond is a covalent bond. The hydrogen atoms share electrons with the sulfur atom, creating a stable molecule..

AlF3: The chemical bond in AlF3 is ionic. Aluminum donates three electrons to fluorine, resulting in the formation of positively charged aluminum ions and negatively charged fluoride ions, which are held together by electrostatic forces..

SiO2: In SiO2, the chemical bond is a covalent bond. Silicon shares electrons with oxygen, forming a stable molecule.
