How many electrons are in 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 Br?
In a neutral atom of bromine there are 35 electrons which are located in shells, n = 1, n=2, n=3 and n=4. It has 7 valence electrons which are located in fourth shell; that is in n = 4. It has 4s and 4p subshells with 2 and 5 electrons respectively. Hence the outermost subshell of bromine is 4p.
What is the outer shell configuration of bromine?

Is bromide A Br?
A bromide ion is the negatively charged form (Br−) of the element bromine, a member of the halogens group on the periodic table.
What does bromine usually bond with?
While it is less reactive than fluorine or chlorine, it is more reactive than iodine. It reacts with many metals, sometimes very vigorously. For instance, with potassium, it reacts explosively. Bromine even combines with relatively unreactive metals, such as platinum and palladium.
Does bromine have a positive or negative charge?

Why is bromine bad for you?
Breathing bromine gas could cause you to cough, have trouble breathing, get a headache, have irritation of your mucous membranes (inside your mouth, nose, etc.), be dizzy, or have watery eyes. Getting bromine liquid or gas on your skin could cause skin irritation and burns.
How long does bromine stay in your system?
Bromide has an elimination half-life of 9 to 12 days, which can lead to excessive accumulation. Doses of 0.5 to 1 gram per day of bromide can lead to bromism.
What happens if you breathe in bromine?
What is the total number of electrons for bromine?
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.
Why does bromine have 7 valence electrons?
It has seven valence electrons in its outermost shell. Because the outermost shell is not “full” (it is short one electron), the bromine atom is not chemically stable and will react with other atoms or molecules until its outermost shell is full.
How many protons, neutrons, and electrons does bromine have?
Bromine is a chemical element with atomic number 35 which means there are 35 protons and 35 electrons in the atomic structure. The chemical symbol for Bromine is Br. Neutron Number and Mass Number of Bromine Mass numbers of typical isotopes of Bromine are 79; 81.
Does bromine react with another type of element?
Halogens such as chlorine, bromine and iodine have properties that enable them to react with other elements to form important salts such as sodium chloride, also known as table salt. Elements such as fluorine, chlorine, bromine, iodine, and astatine belong to Group 17, the halogen group.
