Every oxygen atom has -2 as its oxidation number (and 8 electrons in its valence shells). By balancing the charges, bromine is in +5 state: +6 with six bonds with oxygen and -1 from central charge. After counting the electron that is not involved above--bromine has 14 electrons in its valence shell.
What else can I help you with?
How many total valence electrons make up BrO31?
Bromine has 7 electrons. Three bonds with oxygen give sic electrons and the charge gives one. Therefore, bromine has 14 electrons in valence shell in Bromate(V) ion.
Calcium valence electrons are?
Calcium has a total of two valence electrons.
What is beryllium number of valence electrons?
The beryllium atom has 4 electrons and the valence is 2.
What is the number of valence electrons the element helium has?
Helium has 2 electrons (total of 2 electrons and 2 valence electrons)
How do you find the total valence electrons in an atom?
Valence electrons are on the external shell.
How many total valence electrons make up BrO31?
Bromine has 7 electrons. Three bonds with oxygen give sic electrons and the charge gives one. Therefore, bromine has 14 electrons in valence shell in Bromate(V) ion.
What are the total numbers of valence electrons in LI2O?
To find the total number of valence electrons in Li2O, we add the valence electrons of lithium (1 valence electron each) to the valence electrons of oxygen (6 valence electrons). So, Li2O has 2 (from Li) + 6 (from O) = 8 valence electrons.
Calcium valence electrons are?
Calcium has a total of two valence electrons.
What is beryllium number of valence electrons?
The beryllium atom has 4 electrons and the valence is 2.
What is the number of valence electrons the element boron?
Boron has 3 valence electrons out of five total electrons.
What is the total numbers of valence electrons in IBr?
I (if you count the rows) is at the 7th row, so it has 7 valence electrons. The is the same for Br, so there is a total of 14 electrons. :)
What is the number of valence electrons the element helium has?
Helium has 2 electrons (total of 2 electrons and 2 valence electrons)
How many valence electrons are in nitrogen monoxide?
NO2 Nitrogen has 5 valence electrons Oxygen has (6*2) =12 valence electrons therefore, the total number of valence electron =12 +5 = 17valence electrons.
How many valence electrons does H2SO4?
Each H has 1. Each O has 6 and the S has 6. That's a total of 32 valence electrons.
What are the total numbers of valence electrons in KBr?
Potassium (K) has 1 valence electron and Bromine (Br) has 7 valence electrons. Therefore, the total number of valence electrons in KBr is 1 (from K) + 7 (from Br) = 8 valence electrons.
How do you find the total valence electrons in an atom?
Valence electrons are on the external shell.
