The oxidation numbers of alkali and alkaline earth metals and the highest oxidation numbers that the elements in groups 3A–7A can have are to be given. Concept introduction: The oxidation number is the charge on an atom on complete transfer of electrons. It is the number assigned to an atom that indicates the loss or gain of electrons. The oxidation states are determined by assuming the transfer of electrons to the more electronegative atom in each bond. So, the oxidation state of an atom is negative if it is more electronegative and positive if it is less electronegative. The maximum oxidation state of an atom equals its group number. It is the number of electrons that can be lost from the valence shell.

Interpretation Introduction

Interpretation:

The oxidation numbers of alkali and alkaline earth metals and the highest oxidation numbers that the elements in groups 3A–7A can have are to be given.

Concept introduction:

The oxidation number is the charge on an atom on complete transfer of electrons. It is the number assigned to an atom that indicates the loss or gain of electrons.

The oxidation states are determined by assuming the transfer of electrons to the more electronegative atom in each bond. So, the oxidation state of an atom is negative if it is more electronegative and positive if it is less electronegative.

The maximum oxidation state of an atom equals its group number. It is the number of electrons that can be lost from the valence shell.

(A) if both sentences are true,(B) if both sentences are false,(C) if the first sentence is true but the second is false, and(D) if the first sentence is false but the second is true. 1. In a redox reaction, the oxidation number of iron changed from +2 to +3; thus, sulfur is a reducing agent. In a redox reaction, the oxidation number of nitrogen was unchanged; thus, nitrogen is an oxidant. 2. In a redox reaction, the reducing agent is oxidized and it gains electrons. In a redox reaction, the oxidizing agent is reduced and it gains electrons. 3. Bending stress is also known as flexural stress. The test used in observing the mechanical strength of chocolate is the three-point bend test. 4. The flexural strength of materials may be expressed in Pascals. Magnesium is more reactive than silver; therefore, magnesium corrodes faster than silver with the aid of air, oxygen, and sea water.
