The elecrtons dont go missing they will transfer during reactions. The atom becomes a positive ion if it loses and negative if it gains electrons.
Negative, assuming that the gain of electrons was an ionizing gain (not just replacing missing electrons)
An atom becomes an ion by gaining or losing electrons. When an atom loses electrons, it becomes a positively charged ion (cation) as it has more protons than electrons. On the other hand, when an atom gains electrons, it becomes a negatively charged ion (anion) as it has more electrons than protons.
The number of electrons that must be added or removed to convert an atom into its elemental form is determined by the atom's valence electrons. For example, carbon has 4 valence electrons, so it can either gain 4 electrons to achieve a full outer shell (as in CH4, methane) or lose 4 electrons to achieve a full outer shell (as in C4+, carbide ion).
An S2- ion has gained two electrons, giving it a 2- charge, while a neutral sulfur atom has an equal number of protons and electrons. This means that the S2- ion has two more electrons than a neutral sulfur atom.
If 2 electrons are added to an oxygen atom, it will form an oxygen ion with a charge of -2. The oxygen atom gains a negative charge because it now has two more negatively charged electrons than positively charged protons.
When heat is added to an atom, its electrons gain energy and move to higher energy levels, causing the atom to become excited. When electrical energy is added, it can either cause the atom to gain or lose electrons, leading to the formation of ions. Both processes can result in changes to the atom's chemical properties.
The ATOM decreases in size when it loses an electron and increases when electrons are added.
Valence electrons
When energy is added to an atom, the electrons move to outer levels of the shell. When they drop back down, they release the energy in the form of photons.
If the nucleus is missing an atom, it will try to steel an electron from another atom.
If the nucleus is missing an atom, it will try to steel an electron from another atom.
when an electron is added to an atom, the atom will acquire a negative charge.
A cation is an atom that has lost one or more electrons. An anion is an atom that has gained one or more electrons.
You have Lithium.
It has 8 electrons. And if its not an ion, then it has 8 protons.
