Bromine is a chemical element and has several isotopes.
An alumimium atom is electrically neutral and it is an isotope of aluminum.
Bromine is a chemical element and has several isotopes.
A chromium ion is not neutral. By definition an ion is not neutral. All atoms belong to an isotope, but that has nothing to do with whether the atom is ionized or not.
Neutral atom. An atom of nitrogen will also be an isotope of nitrogen.
Helium is a neutral atom that has several isotopes and can become an ion.
Br is a chemical element symbol for bromine. It exists as neutral atoms in its most common form. An isotope would refer to different forms of bromine with varying numbers of neutrons, while an ion would indicate a charged species of bromine due to gaining or losing electrons.
This atom of Nitrogen with 7 protons, 7 neutrons, and 8 electrons is an isotope, specifically nitrogen-14. It is not an ion because it has an equal number of protons and electrons, so its charge is neutral. It is also not an average atom, as it has a specific number of protons and neutrons that define it as a particular isotope.
Xenon can exist as both a neutral atom and in various isotopic forms. Isotopes of xenon have different numbers of neutrons in their nuclei, but they all have the same number of protons, making them still xenon atoms. When xenon gains or loses electrons, it forms ions.
That depends: is it a positive ion (Br+) or a negative ion (Br-)? An ion with a charge of +1 has one less electron than the element would have normally. An ion with a charge of -1 has one more electron than normal. It seems kind of strange that -1 means one more, and +1 means one less, but that's because an electron has a charge of -1, so if there is one less electron than is needed to keep the atomic charge balanced, the charge will be positive by 1. Cations (pronounced cat-ions, not cashons), ions with a positive charge and therefore fewer electrons than the neutral atom, have a smaller atomic radius than the neutral atom. Anions, ions with a negative charge and therefore more electrons than usual, have a larger atomic radius than the neutral atom. So a bromine cation would have a smaller radius, and a bromine anion would have a larger atomic radius. NOTE: when referring to a neutral atom, the atom is of THE SAME ELEMENT as the ion. Otherwise, the comparison is not necessarily true.
"Bromine" is the name of an atom or an element. The corresponding ion is named "bromide".
Bromine has 35 electrons in its neutral state, and, as it is a halogen, 36 in its most stable ion. So it would have 4 shells, with 2, 8, 18, and 7 electrons in the neutral state, or 2, 8 ,18 and 8 electrons in its stable ion.
An iodine atom has the same number of electrons as a bromine ion. Both elements belong to the halogen group and have seven valence electrons. When bromine gains one electron to become an ion, it will have a full outer shell with eight electrons, the same electron configuration as iodine.
