Group seven elements are:
- manganese
- technetium
- rhenium
- bohrium
Manganese is a component used in the manufacture of stainless steel. Stainless steel is used to skin appliance, or shelving, and refrigeration tubing and compressor tanks. Manganese phosphate is used for rust treatment of iron and steel.
Technetium is radioactive and has no stable isotopes so is not used in appliance manufacturing.
Rhenium is the rarest transitional metal on Earth. It is used in the manufacture of jet engines and rockect motor valves. Because of its rarity, it is one of the most costly metals known, selling for around $150.00 a troy ounce.
Bohrium is an artficially formed element, it does not exist in nature, and the most stable isotope has a halflife of 61 seconds.

Why are group 7 elements used in refrigerators?
Group 7 elements, like fluorine and chlorine, are used in refrigerators because they are halogens with high electronegativity. They can be used as refrigerants due to their ability to easily change between gas and liquid states at room temperature, making them effective at absorbing and releasing heat as needed for the refrigeration process. Additionally, their low boiling points make them suitable for use in refrigeration systems.
Are both elements and compounds essential for life?
Yes, both elements and compounds are essential for life. Elements are the basic building blocks of all matter, while compounds are formed when elements combine in specific ways. In living organisms, elements are used to form compounds that are necessary for various biochemical processes to occur.
What compounds are used in refrigerators?
The compound used in older refrigerators was Chloroflurocarbons which is commomly called as CFC's and the recent ones uses compounds of florides and Hydroflurocarbons which is commonly called as HFC's. CFC's are replaced by HFC's due to their reactivity with the Ozone layer and causes depletion. Hope this helps.

What criteria is used to choose which group an element belongs to?
Elements are classified into groups on the periodic table based on their similar chemical properties and reactivity. Elements in the same group have the same number of valence electrons, leading to similar bonding behavior and chemical reactions. This grouping helps predict the behavior of elements and their compounds.
Why compounds of group 7 elements are used for X-ray photography?

Why are elements of group 1 alkali metals and group 7 halogens used as compounds and not as the free elements?
Alkali metals from group 1 are very reactive and can easily react with air or moisture to form compounds. Halogens from group 7 are also highly reactive and tend to form compounds with other elements to satisfy their valence electron configuration. Therefore, it is more common to find them as compounds rather than in their free elemental form.
Why are the elements of group 1 and 7 are mostly used in the form of compounds?
Elements from group 1 (alkali metals) and group 7 (halogens) are highly reactive due to their electronic configurations. As a result, they tend to form compounds easily to achieve more stable electron configurations. Compounds with these elements often exhibit useful properties in various chemical reactions and industrial applications.
What are some commonly used compounds on the periodic table?
There are NO compounds in the Periodic Table. They are all Elements.
How is elements related to compounds?
Elements are the "building blocks" used to "build" compounds. Elements are the "letters of the alphabet" with which the "words" of compounds are "written". Not perfect analogies, but they should give you an idea.
Where are refrigerators used?
Refrigerators are used in houses
How group 7 compounds are used in x-ray photography and agriculture?
Group 7 elements, such as manganese in the form of potassium permanganate, are used as contrast agents in medical radiography to enhance visualization and improve diagnostic accuracy. In agriculture, group 7 compounds like manganese sulfate are used as micronutrient fertilizers to correct manganese deficiencies in crops and promote healthy growth.
Why are groups 1 and 7 elements used as compounds?
Groups 1 and 7 elements are used as compounds because they have a tendency to form stable compounds due to their reactivity. Group 1 elements (e.g. sodium, potassium) are highly reactive metals that readily lose an electron to form a +1 cation, while Group 7 elements (e.g. chlorine, fluorine) are highly reactive nonmetals that readily gain an electron to form a -1 anion. When combined, they form ionic compounds with a 1:1 ratio of cations to anions, such as sodium chloride (NaCl) and potassium iodide (KI).
Roman numeral should be used when naming which compounds?
Compounds which contain transition elements. cu2so4
Are both elements and compounds essential for life?
Yes, both elements and compounds are essential for life. Elements are the basic building blocks of all matter, while compounds are formed when elements combine in specific ways. In living organisms, elements are used to form compounds that are necessary for various biochemical processes to occur.
What suffix is used in forming the proper names of elements and compounds?
The suffix used in forming the proper names of elements and compounds is "-ide". This suffix is added to the end of the name of the element when it forms a negative ion or combines with other elements to form compounds.
