What element has -1 as an oxidation number?
The halogens (group 17) have an oxidation number of -1, though the halogens below fluorine can have other oxidation numbers as well. Hydrogen can also have an oxidation number of -1 when it forms hydrides.
What is the oxidation number of group 17 elements?
There are some numbers. Every element shows -1 number.
What is the common oxidation number for all elements in group 17 of the periodic table?
-1.
Why do elements in group 17 have an oxidation number of -1?
Because they require one electron to complete their octet
What is the oxidation number for all the elements in the carbon group?
You are asking about group 12. Generally they shows 14 as the oxidation number.
What is group 17 oxidation number?
-1 only for F Other elements could have -1 to +7 depending on the compound
What is the most common oxidation number of the element chlorine?
Chlorine is in group 17. It easily accepts an electron from another element to fill its valence shell. As it takes one electron, its oxidation number changes to -1.
What is the oxidation number for group 2 elements?
Hydrogen has -1 and +1 oxidation numbers. Other elements have +1 only
Elements that have a single oxidation number?
Group 1 elements have +1 oxidation number (except for hydrogen) All group 2 elements have +2 oxidation number Fluoride ion always has -1
What group has variable oxidation numbers?
Groups 1 and 2 are +1 and +2 respectivelly.. Group 3-12 have variable oxidation numbers - they are the so-called transition metals. Group 14-17 have variable oxidation numbers -even group 18- has- there are a number of different compounds of Xe for example. Group 1 and 2 have some strange compounds such as Cs11O3 . A better question might be which group doesn't have variable oxidation numbers!
