Question

Oxides of virtually every element are known. Bromine, for example, forms several oxides when treated.

a) True
b) False

Answer 1

The statement is false. Not all elements form oxides, and bromine is an example of an element that does not readily form oxides. While bromine can react with certain substances, it does not typically form stable oxides under normal conditions.

Step-by-step explanation:

Bromine, a halogen in Group 17 of the periodic table, is known for its reactivity and tendency to form compounds, especially with metals. However, it does not readily form oxides like some other elements. Oxides are compounds formed by the reaction of an element with oxygen, but bromine's electronic configuration and bonding behavior make the formation of stable oxides less favorable.

In the periodic table, elements in Group 16 (oxygen, sulfur, selenium, etc.) are more likely to form oxides due to their tendency to gain electrons and achieve a stable electronic configuration. Bromine, being in Group 17, is more inclined to form compounds through gaining or sharing electrons rather than directly reacting with oxygen to form oxides. Therefore, the assertion that bromine forms several oxides is not accurate, and it highlights the importance of considering the specific properties and behavior of each element when making general statements about their reactivity.

In conclusion, while bromine is chemically active and can form various compounds, the formation of oxides is not a characteristic behavior of bromine, making the initial statement false. It is essential to base such claims on the specific chemical properties and behavior of each element to provide accurate information about their reactivity and the compounds they are likely to form.

Answer 2

True, bromine can form several oxides when treated, which is consistent with the behavior of many elements that react with oxygen under the right conditions to form oxides.

Step-by-step explanation:

The question asks whether bromine forms oxides when treated, which is a true statement. Reactive elements like fluorine and oxygen can form compounds with other elements, including oxides. While heating is often required to facilitate these reactions, some metals naturally react with oxygen to form oxides. For example, transition metals can react with oxygen, although some like palladium, platinum, silver, and gold usually form oxides through other reactants and will decompose upon heating. Similarly, f-block elements and group 3 elements create oxides and react with acids in aqueous solutions to form hydrogen gas. In the case of bromine, it can react under certain conditions to form a range of oxides, such as bromine dioxide (BrO2) or bromine trioxide (BrO3).
