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 cation is an atom that has (lost/gained) an electron, giving it a (positive/negative) electrical charge. Which neutral atom has the same number of electrons as a Ca2+ ion? Cations have: a. positive charge b. negative charge c. no charge d. It is impossibl...
An atom's valence electrons are those electrons that can be gained or lost in a chemical reaction. Because the electrons that occupy filled d or f subshells are seldom disturbed in a chemical reaction, we can also define an atom's valence electrons as the electrons that are not present in...
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...

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....
electrons from its valence shell. An anion is formed when an electron is gained by an atom. The anion has a net negative charge in it. A cation is formed when an electron is lost by an atom from its valence shell. The cation has a net positiv...
ions are formedby gain or loss of an electron from an atom or molecule. If an atom or molecule gains an electron, it becomes negatively charged (an anion), and if it loses an electron, it becomes positively charged (a cation). Energy may be lost or gained in the formation of an ion...
