Bromine is a chemical element and has several isotopes.
Bromine is a chemical element and has several isotopes.
The number of neutrons in a bromine atom can vary depending on the isotope. The most common isotope of bromine, ^79Br, has 44 neutrons.
"Bromine" is the name of an atom or an element. The corresponding ion is named "bromide".
An alumimium atom is electrically neutral and it is an isotope of aluminum.
Helium is a neutral atom that has several isotopes and can become an ion.
In the reaction, bromine gains an electron and forms a bromide ion (Br-). This results in a decrease in the oxidation state of the bromine atom from 0 to -1.
This is not an atom. This is an ion. This is Na+ ion.
ion
Bromine loses an electron and forms a bromide ion by gaining one electron in the reaction with sodium. Sodium donates its electron to bromine, making the bromine atom gain one electron and become a bromide ion during the reaction.
A bromine ion with only 26 electrons is not possible. A bromine atom has 35 electrons and it can't loose 9 electrons.
Neutral atom. An atom of nitrogen will also be an isotope of nitrogen.
You call it an ion of that isotope. Let's use carbon-14 for example. If a carbon-14 atom gains/loses an electron, you simply call it a "carbon-14 ion".
