chlorine ion has 17 protons and 18 electrons.
Ions with 18 electrons are exceptions (ex.: Cl-).
None.H2S is a covalent compound, there are no ions as the electrons are shared between the hydrogen and sulfur.
A Plasma must contain many ions and electrons.
Ions that are deficient in electrons are called cations. Cations have a positive charge due to the lack of electrons compared to the number of protons in the nucleus. These ions are typically formed by metals losing electrons during chemical reactions.
Ions do not share electrons with other atoms. Ions are formed when atoms gain or lose electrons to achieve a stable electron configuration. Positive ions (cations) lose electrons, while negative ions (anions) gain electrons.
There are many different types of ions, having many different quantities of electrons and protons. The H+ ion has one proton and no electrons. That's the simplest.
Ions. Cations have lost electrons and have a positive charge. Anions have gained electrons and have a negative charge.
I do not understand the question Aluminium forms the Al3+ ion Aluminium is a metal and one description of metal bonding is that metals are latttices of ions surrounded by electrons.
To be neutral, Bromine (atomic symbol Br) has 35 electrons. Ions have more or less.
