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.
Does bromine have 1 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.
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.
What is Br valence?
Bromine is an element which belongs to the halogen family with atomic number 35. Bromine has 7 valence electrons and the valency of bromine is 1.
How do you determine valence electrons?
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.
Why does bromine have 17 valence electrons?
0:051:22How to Find the Valence Electrons for Bromine (Br) – YouTubeYouTube
How do you find the valency of a bromine?
Valency is defined as the combining power of an element and is determined by the number of valence electrons in the outermost shell of an element. Bromine is an element which belongs to the halogen family with atomic number 35. Bromine has 7 valence electrons and the valency of bromine is 1.
How do you figure out valence electrons?
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.
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 valence electrons are in the element B?
3 valence electrons Boron has 3 valence electrons.
What are the 7 valence electrons?
The family of elements having seven electrons in the valence shell is halogens, i.e., chlorine, fluorine, bromine, iodine, astatine.
What is the easiest way to find valency?
The valency of an atom is equal to the number of electrons in the outer shell if that number is four or less. Otherwise, the valency is equal to eight minus the number of electrons in the outer shell. Once you know the number of valence electrons, you can easily calculate the valency. Was this answer helpful?
How do you know the valence electrons?
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.
How do you find valence electrons?
Now that you know your element's electron shells, finding the valence electrons is easy: just use the number of electrons in the outermost shell. If the outer shell is full (in other words, if it has eight electrons or, for the first shell, two), the element is inert and will not react easily with other elements.
How do you find 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.
How do I find valence electrons?

What element has the valence of 7?
Any element in the halogen group will have seven valence electrons. These elements include fluorine, chlorine, bromine, iodine, and astatine.
How many valence electrons are in each atom?
As a general rule, a main-group element (except hydrogen or helium) tends to react to form a s2p6 electron configuration. This tendency is called the octet rule, because each bonded atom has 8 valence electrons including shared electrons.
What is a valence of an element?
valence, also spelled valency, in chemistry, the property of an element that determines the number of other atoms with which an atom of the element can combine. Introduced in 1868, the term is used to express both the power of combination of an element in general and the numerical value of the power of combination.
What are the valence electrons of all elements?
The outermost shell of hydrogen (H), lithium (Li), and sodium (Na) atoms all have one electron. As a result, each of them has the potential to lose one electron. As a result, they have a valency of one….Valency.
| Atomic Number | Element | Valence Electrons |
|---|---|---|
| 6 | Carbon (C) | 4 |
| 7 | Nitrogen (N) | 5 |
| 8 | Oxygen (O) | 6 |
| 9 | Fluorine (F) | 7 |

How do you do valency?
The valency of an atom is equal to the number of electrons in the outer shell if that number is four or less. Otherwise, the valency is equal to eight minus the number of electrons in the outer shell. Once you know the number of valence electrons, you can easily calculate the valency. Was this answer helpful?
How do you calculate valence?
The ones digit in the group number is the number of valence electrons. To solve without a periodic table, find the electron configuration of the element and count the electrons into 1 group of 2, and then into shells of 8. The number in the last group is the amount of valence electrons.
