How many electrons are on the outer shell of bromine?
seven electrons
The Group 7 elements – fluorine (F), chlorine (Cl), bromine (Br), iodine (I) and astatine (At) – have seven electrons in the outer shell.
What is the outermost shell for bromine?
Outermost subshell for bromine, Br is ‘4p’.
What is the outer shell electron configuration for Br?
Bromine Atomic and Orbital Properties

Does bromine have 7 or 17 valence electrons?
Bromine has an electron configuration of 1s22s22p63s23p64s23d104p5 the valence electrons are in the 4s and 4p orbitals giving Bromine 7 valence electrons.
Why does bromine have 18 electrons in its third shell?
A s orbital, a set of (3)p orbitals and a set of (5)d orbitals form the 3rd subshell. Each orbital carries 2 electrons and you can actually find that 18 electrons can be shot in. This is because it is the 3rd shell’s full power and it does not say the order in which the electrons are filled.
What is the Br valence shell?
Valence shell configuration of bromine is 4s24p5. Therefore Bromine has 7 valance electrons.
How many valence shell electrons are in bromine?
7 valence electrons
Bromine has an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p5 the valence electrons are in the 4s and 4p orbitals giving Bromine 7 valence electrons.
How many valence electrons does Br bromine have?
What is valence shell of bromine?
How do you find electrons in shells?
Each shell can contain only a fixed number of electrons: the first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.
How many electrons are in the third shell of bromine?
The third shell can hold 32 electrons. Within the shells, electrons are further grouped into subshells of four different types, identified as s, p, d, and f in order of increasing energy.
Why is the third shell 8 or 18?
Each shell can contain only a fixed number of electrons, up to two electrons can hold the first shell, up to eight (2 + 6) electrons can hold the second shell, up to 18 (2 + 6 + 10) can hold the third shell and so on.
How many pairs of valence electrons does Br have?
The answer is B) 3.
How many electrons are there in the shell?
Each successive shell can only hold a certain number of electrons. The innermost shell is filled first. This shell can contain a maximum of two electrons. The second shell can hold a maximum of eight electrons….Electron shells.
| Energy shell | Maximum number of electrons |
|---|---|
| Third | 8 |
How do you find the number of electrons in the outer shell?
So we can use the column or group of an element to determine the number of electrons in its outermost shell, sometimes referred to as valence electrons. Elements from the fourth column of the periodic table, like carbon, have four electrons in their outermost electron shell or four valence electrons.
