Question

10. Classify each as an ionic compound, molecular compound, molecular element, or atomic element, based on the chemical formula.

NiCl₂_______________________________

N2O₄: _____________________________

H2: _____________________________

PCl₅: ________________________________

Ar: ____________________________

TiBr₃: ______________________________

Answer 1

Sol:(1)NiCl2=ionic compound (because the ions are held by electrostatic force and it gives it's ions in solutiin)

(2) N2O4= it is molecular compound as nitrogen and oxygen are nonmetal and the bond between them is covalent.

(3) H2=it is molecular element as it is present as diatomic gas.

(4) PCl5=it is molecular compound as there is covalent bond between P and Cl.

(5) Ar=atomic element as it is an element in the periodic table.

(6) TiBr3=ionic as there is a bond between metal and nonmetal.
