How do you calculate valence?
For neutral atoms, the number of valence electrons is equal to the atom's main group number. The main group number for an element can be found from its column on the periodic table. For example, carbon is in group 4 and has 4 valence electrons. Oxygen is in group 6 and has 6 valence electrons.
Does bromine have 7 or 17 valence electrons?
1 Answer. Valence electrons found in the s and p orbitals of the highest energy. Bromine has an electron configuration of 1s22s22p63s23p64s23d104p5 the valence electrons are in the 4s and 4p orbitals giving Bromine 7 valence electrons.
Why is the valency of bromine 7?
Valency is the combining power of an element. It is determined by the number of valence electrons in the outermost shell of the element. Bromine has atomic number 35, which means it has 7 electrons in its valence shell. It needs one more electron to attain the noble gas configuration.
How can we find valency?
Mathematically we can say that if the outermost shell of an atom contains 4 or less than 4 electrons, then the valency of an element is equal to the number of electrons present in the outermost shell and if it is greater than 4, then the valency of an element is determined by subtracting the total number of electrons …
How many outer electrons does bromine have?
seven electrons Like the other halogens, bromine has seven electrons in its outer shell and is very reactive. You will find bromine in many salt compounds with alkali metals.
Does bromine have 17 valence electrons?
Valence shell configuration of bromine is 4s24p5. Therefore Bromine has 7 valance electrons.
Why does Br have 7 valence electrons?
The last shell after the electron configuration is called the valence shell. The total number of electrons in a valence shell is called valence electrons. The electron configuration shows that the last shell of bromine has seven electrons. Therefore, the valence electrons of bromine(Br) are seven.
How can we calculate valency?
Mathematically we can say that if the outermost shell of an atom contains 4 or less than 4 electrons, then the valency of an element is equal to the number of electrons present in the outermost shell and if it is greater than 4, then the valency of an element is determined by subtracting the total number of electrons …
What is the easiest way to find valency?
