How many dots are on the dot diagram for bromine?
seven dots
How many dots should there be in a bromine atom’s Lewis symbol? In bromine’s atom Lewis electron dot diagram there should be seven dots arranged correctly, as it has seven valence electrons.
Does bromine lose or gain electrons?
The atomic number for bromine is 35, which means it has 35 protons in its atomic nuclei. A neutral bromine atom would also have 35 electrons. In order for a bromine atom to become a 1− bromide ion, it would have to gain an additional electron.
How many valence electrons does chlorine have?
seven valence electrons
A: An atom of a group 17 element such as chlorine has seven valence electrons.
How many dots does chlorine have?
As you can see Chlorine is now surrounded by 8 electrons in the n=3 shell and Sodium has lost its one valence electron in the n=3 shell. Of course, Sodium, is still surrounded by the 8 electrons of the n=2 shell, but we do not show electrons in the inner closed shells….Lewis Dot Structures.
| Bond | Bond Length |

| N≡N | 1.10 Å |
Does chlorine gain or lose electrons?
Chlorine gains an electron, leaving it with 17 protons and 18 electrons. Since it has 1 more electron than protons, chlorine has a charge of −1, making it a negative ion. When ions form, atoms gain or lose electrons until their outer energy level is full.
How many electrons does Br gain?
Explanation: The atomic number for bromine is 35, which means it has 35 protons in its atomic nuclei. A neutral bromine atom would also have 35 electrons. In order for a bromine atom to become a 1− bromide ion, it would have to gain an additional electron.
How many electrons does BR have?
35 electrons
The neutral atom of bromine has 35 electrons because the number of electrons equals the number of protons.
How many valence electrons does Chloride have?
Does bromine gain or lose electrons?
In order for a bromine atom to become a 1− bromide ion, it would have to gain an additional electron. Below is the Lewis dot structure for a neutral bromine atom, which has seven valence electrons. Below is the Lewis dot structure for a Br− ion, which has eight valence electrons.
