Manganese (Mn) has many uses in the modern technology.
# Rhenium (Rh) is very rare and expensive.
# Technetium (Tc) is obtained only from burned nuclear fuels - also expensive, rare, radioactive.
# Bohrium (Bh) is an artificial element, radioactive, very unstable and only some atoms can be prepared.

Why is there not many uses of elements?
False; practically all the chemical elements have many uses.
Why group 7 element by their self do not have many uses?
This situation is normal. The number of chemical elements is smaller compared to the number of chemical compounds.
What property of the element does the group number identify in a numbering system that uses a and b?
Pretty sure it's the valence electrons
Why does the group 7 elements not have many uses?
The answer to this question depends on which version of the periodic table you're referring to.According to IUPAC, Group 7 would consist of manganese (Mn), technetium (Tc), rhenium (Rh), and bohrium (Bh). This group does not have many uses because other than manganese, the others are either rare or synthetic. Manganese is used as an alloying material in steel and is crucial to Vitamin B1.If all of the transition metals are considered to be one group (or the old IUPAC/CAS method is used), then group 7 can refer to the halogens, or fluorine (F), chlorine (Cl), bromine (Br), Iodine (I), and Astatine (At). These elements are highly reactive and are famous for producing salts when combined with Group 1 or Alkali metals. These elements may not have many uses alone, but they have a crucial role in chemistry.
What are the uses of group 1 and 7 elements?
Group 1 elements, such as sodium and potassium, are used in various applications including making soap, fertilizers, and as components in alloys. Group 7 elements, such as chlorine and fluorine, are used in disinfectants, water treatment, and as components in materials like PVC and Teflon.
What property of an element does the group number identfiy in a numbering system that uses A and B?
In a numbering system that uses A and B, the group number typically identifies the number of valence electrons in the outermost shell of the elements. For example, elements in group A (1A to 8A) have valence electrons ranging from one to eight, which influences their chemical properties and bonding behavior. This classification helps predict how elements will react with one another based on their electron configurations.
What are the uses of rare earth elements?
your TV, smart phone, car, head phones, speakers all use rare earth elements. there are many types of rare earth elements that all have different uses.
What group number identify in a numbering system that uses A and B?
In a numbering system that uses A and B, the group number typically refers to the position or classification of elements within a periodic table or a specific set of data. For example, in the context of chemistry, group A might represent main group elements, while group B could signify transition metals. The specific meaning can vary based on the context, so it's essential to clarify the system being used.
What do the elements nitrogen phosphorus and arsenic have in common?
Nitrogen, phosphorus, and arsenic are all elements found in group 15 of the periodic table. They are all nonmetals and have various industrial uses. Nitrogen and phosphorus are essential elements for life, while arsenic is toxic.
