Answer 2

Valence of Al2O3 (Aluminum Oxide):

The valence of an element refers to its combining power with other elements to form compounds. In the case of Al2O3, also known as aluminum oxide, the valence of aluminum (Al) is +3, and the valence of oxygen (O) is -2. This means that aluminum has a tendency to lose three electrons to achieve a stable configuration, while oxygen has a tendency to gain two electrons. The compound Al2O3 is formed when two aluminum atoms combine with three oxygen atoms, with each aluminum atom losing three electrons and each oxygen atom gaining two electrons. [[1]]

Valence of ZnO (Zinc Oxide):

The valence of zinc (Zn) in ZnO, or zinc oxide, is +2, and the valence of oxygen (O) is -2. This means that zinc has a tendency to lose two electrons, while oxygen has a tendency to gain two electrons. In the compound ZnO, one zinc atom combines with one oxygen atom, with the zinc atom losing two electrons and the oxygen atom gaining two electrons. [[2]]

Valence of N2O3 (Dinitrogen Trioxide):

The valence of nitrogen (N) in N2O3, or dinitrogen trioxide, is +3, and the valence of oxygen (O) is -2. This means that nitrogen has a tendency to lose three electrons, while oxygen has a tendency to gain two electrons. In the compound N2O3, two nitrogen atoms combine with three oxygen atoms, with each nitrogen atom losing three electrons and each oxygen atom gaining two electrons. [[3]]

Valence of P2O5 (Phosphorus Pentoxide):

The valence of phosphorus (P) in P2O5, or phosphorus pentoxide, is +5, and the valence of oxygen (O) is -2. This means that phosphorus has a tendency to lose five electrons, while oxygen has a tendency to gain two electrons. In the compound P2O5, two phosphorus atoms combine with five oxygen atoms, with each phosphorus atom losing five electrons and each oxygen atom gaining two electrons. [[4]]

Valence of Cl2O7 (Dichlorine Heptoxide):

The valence of chlorine (Cl) in Cl2O7, or dichlorine heptoxide, is +7, and the valence of oxygen (O) is -2. This means that chlorine has a tendency to lose seven electrons, while oxygen has a tendency to gain two electrons. In the compound Cl2O7, two chlorine atoms combine with seven oxygen atoms, with each chlorine atom losing seven electrons and each oxygen atom gaining two electrons. [[5]]

In summary, the valence of the given compounds is as follows: - Al2O3: Aluminum (Al) has a valence of +3, and oxygen (O) has a valence of -2. - ZnO: Zinc (Zn) has a valence of +2, and oxygen (O) has a valence of -2. - N2O3: Nitrogen (N) has a valence of +3, and oxygen (O) has a valence of -2. - P2O5: Phosphorus (P) has a valence of +5, and oxygen (O) has a valence of -2. - Cl2O7: Chlorine (Cl) has a valence of +7, and oxygen (O) has a valence of -2.
