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.
A neutral atom has an equal number of protons and electrons. Protons are positively charged, and electrons are negatively charged. Therefore if you have an ion with a -1 charge, it has one extra electron. So your ion has 85 protons.
Chlorine-35 has 17 electrons. Chlorine has 17 protons, and since it is electrically neutral, it also has 17 electrons to balance the positive charge of the protons.
Neutrons are 'zero' charged. Protons are positively(+) charged. Electrons are negatively(-) charged. For any neutrally charged atom , the number of protons(+) equals the number of electrons(-); the charges balance. However, when an atom loses or gains electrons it becomes a charged species and is called an ION , not an atom. If the number of protons changes then it is a completely different element. Neutrons have no effect on the charge of an atom/ion, they only effect the atomic mass. Here are some examples. Hydrogen has one proton and one electrons ; charges balance. However the hydrogen ion has one proton and no electrons (H^+) Chlorine has two isotopes l different number of neutrons Chlorine - 35 , 17 protons , 18 neutrons and 17 electrons The Chloride(-35) ion has 17 protons , 18 neutrons and 18 electrons (35)Cl^-) , the chloride -35 ion Chlorine - 37, 17 protons , 20 neutrons and 17 electrons The Chloride(-37) ion has 17 protons , 20 neutrons, and 18 electrons (37)Cl^-) , the chloride - 37 ion. The Chloride(-37) ion has 17 protons, 20 neutrons and 18 electrons Notice , for the given element the number of protons remains the same, the different isotopes have different number of neutrons, and the ions have a different number of electrons.
An ion of bromine typically has 36 electrons since bromine has 35 electrons in its neutral state, but the charge of the ion will determine the exact number.
Protons = 17, electrons = 18There are two isotopes differing in neutron number only :Cl-35 (75%) having 35-17= 18 neutronsCl-37 (25%) having 37-17= 20 neutrons
35
35 protons, 36 electrons
A neutral atom has an equal number of protons and electrons. Protons are positively charged, and electrons are negatively charged. Therefore if you have an ion with a -1 charge, it has one extra electron. So your ion has 85 protons.
Br has an atomic number of 35 giving it 35 protons. Since it has a charge of 1- it will have 36 electrons to form a octet.Br- will have 35 protons and 36 electrons. The negative charge indicates it gained an electron.
The element bromine has an atomic number of 35. This means that each atom contains 35 protons, and the requirement for electrical neutrality in an atom means that the atom also contains 35 electrons. A bromide ion contains one more electrons than a bromine atom: 36.
This ion would be an atom of phosphorus with a +3 charge, as phosphorus typically has 15 electrons and 15 protons (which gives it a neutral charge). The number of neutrons doesn't affect the charge of the ion, so it would still be considered a phosphorus ion with a +3 charge.
29 protons and 27electrons are present in Cu2+ ion.
Chlorine-35 has 17 electrons. Chlorine has 17 protons, and since it is electrically neutral, it also has 17 electrons to balance the positive charge of the protons.
A bromine ion with only 26 electrons is not possible. A bromine atom has 35 electrons and it can't loose 9 electrons.
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)
