An atom that has gained or lost one or more electrons and, as a result, carries a negative or positive charge. light Electromagnetic radiation detectable by the eye, ranging in wavelength from about 400 to 750 nm. In photonic applications light can be considered to cover the nonvisible portio...
which has fewer electrons than protons is known as a cation. Ions are denoted in the same way as electrically neutral atoms and molecules except for the presence of a superscript indicating the sign of the electric charge and the number of electrons lost or gained if more than one...
Ions are the name for atoms that have gained or lost one or more electrons, leaving them with a net charge. For atoms that lose an electron, they gain a positive charge and become cations. For atoms that gain an electron, they take on a net negative charge and become anions. These are...

A polyatomic anion that contains oxygen is sometimes known as an oxyanion . Ions are denoted in the same way as electrically neutral atoms and molecules except for the presence of a superscript indicating the sign of the electric charge and the number of electrons lost or gained if...
In a positive ion the atom, having lost k electrons (an ionized atom), retains Z − k electrons (k = 1, 2, 3, . . .—the multiplicity of ionization) and its charge is +ke; in a negative ion the atom, having gained k electrons, has Z + k electrons, and its charge is -ke...
The oxidation number, or oxidation state, is a positive or negative integer value assigned to an atom in a chemical compound. It describes the number of electrons lost (positive value) or gained (negative value) in that atom...
Atoms form ions by gaining and loosing electrons. The ions are charged because the positively charged protons and negatively charged electrons do not cancel each other. The electrons are lost to form positively charged ions while electrons are gained to form negatively charged ions....
From a conservation of energy standpoint, atom B has gained all the energy that atom A has lost, so there is no net energy change to the system. All the energy of atom A’s excited state has been “spent” in raising atom B to the same excited state. But I also recall reading ...
