Br- has 36 electrons.
Bromide: Group 17, Period IV:
(K,L,M,N): 2, 8, 18, 7+1 (1 extra for Br-) = total 35+1= 36 electrons

What charge is on an ion with 35 protons and 38 electrons?
By definition, every atom of every element must have the same number of protons as every atom of that same element. So, all you have to do is find which element has 35 protons. Look at the periodic table, and find the 35th listed element. That element is Bromine. So Bromine is the correct answer.
Does an element that loses electrons when bonding with other atoms have a negative oxidation number?
No. The lower (or 'more negative') the oxidation number, the more electrons the atom has. This is because the oxidation number is a measure of the charge on that molecule and, since electrons have negative charge, more of them give a more negative oxidation number. So if an atom loses electrons during bonding, it has lost some of its negative charge - giving it a more positive oxidation number.
What is the relative charge of a electron?
Protons have positive charge and electrons negative
What is the outer ring number of electrons for bromine?
There are 7 electrons in the outer "ring" of bromine.
What is the formal charge for BrO2?
The formal charge on bromine in the molecule HBr is -1. There are a number of rules for assigning the formal charge to an atom. The most important of them is that the sum of the formal charges on each atom must equal the charge on the molecule or ion. Since the Br has a formal of -1 and the charge on HBr is zero, then the formal charge on the hydrogen atom must be +1. The bromine atom has a formal charge of -1 because another important rule is that the most electronegative atom will have a negative formal charge equal to the number of electrons it needs to fill all of its outer orbitals. Since bromine has seven electrons, it needs one electron to fill its outer shell.

What has 35 protons 45 neutrons and 36 electron?
Since it has 35 protons, it's atomic number is 35, which is the atomic number of Bromine. Bromine has an average Atomic Mass of 79.9 which would account for the 45 neutrons. Normally the number of electrons and protons are the same. Since there are 36 electrons that means there is one extra electron beyond the 35 protons. This means that the Bromine atom has gained an electron and is no longer electrically neutral. It is an ion with a charge of negative one (-1)
Why doesnt An atom has no electrical charge?
because the number of protons (which have a positive charge of +1) and the number of electrons (which have a negative charge of -1) are the same. when number of protons = number of electrons, overall charge = 0
What is the relative charge of a electron?
Protons have positive charge and electrons negative
Why does bromine commonly have -1 charge while potassium has a plus 1 charge?
Because of the number of electrons in the outermost shell of the atom.
Why are protons related to electrons with a negative charge?
In a neutral atom, the number of protons is equal to the number of electrons. Since each proton has a charge of +1, and electrons have a charge of -1, the positive and negative charges balance each other, and the atom will be neutral.
Why An anion has a negative charge?
When an atom gains electrons, it has a net negative charge and is known as anion. An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons.
What is the outer ring number of electrons for bromine?
There are 7 electrons in the outer "ring" of bromine.
What kind of charge can move from object to object?
Electrons can move from object to object. Electrons have a negative charge. So if an object is determined to have a positive charge, then some of the electrons have moved from the object to somewhere else. Something with a neutral charge has the same number of electrons [-] and protons [+]. If electrons [-] leave, then there will be more protons, and a net positive charge. If an object gains electrons, then the object has a net negative charge.
How many unpaired electrons does phosphorus with the charge of negative three have?
18. Phosphorus posses 15 electrons and 15 protons, respectively its charge is 0.By accepting 3 more electrons, with their negative charge the total charge of the atom would decrease by 3.So the total charge would be -3 and the total number of electrons would be 18.
What do you get if the number of protons and electrons are not equal?
An ion, which would have a positive charge if there are more protons, and a negative charge id there are more electrons.
