Which process changes a lithium atom into a lithium ion?

Answer 1

The primary difference between an atom and an ion is that the ion is charged. Let's look a bit more closely and at how ions are formed to get a handle on things. Ions are atoms that have a greater or a fewer number of electrons than protons. When these atoms have borrowed or loaned out electrons, they end up electrically "imbalanced" and have an overall charge. If they are "short" electrons, they are positively charged, and if they have "extra" electrons, they are negatively charged. When atoms enter into bonding arrangements, they will share, or will loan or borrow electrons. In the case of loaning and borrowing electrons, the atoms will be forming ionic bonds, and the atoms form the molecule. But when we put the substance in the a solvent, the ions will appear. Let's take an example. If we consider table salt, which is sodium chloride (NaCl), when the salt is dissolved in water (dissociation), the ions of sodium (Na+) and chlorine (Cl-) form in solution. The sodium atom has loaned out its one valence electron, and chlorine has borrowed it. The two atoms are now ions with a charge of plus one and minus one, respectively. And these ions are what are floating around in solution in the water. Ions can also be formed in situations where any atoms are in an "environment" of high energy. In a fluorescent light, for example, high voltage acts on the gas atoms in the tube, and the outer electrons are torn off momentarily to support conduction. This creates ions out of the gas atoms. The atoms are said to be electrically ionized. The electrons then "fall back" into their orbitals by emitting light photons (electromagnetic energy) in doing so. Fluorescent tubes have ionized gas in them when they are operating. Lastly, in environments where it is extremely hot, the thermal energy is so great that it will drive electrons out of their orbitals and thermally ionize the atoms. Superheated material that is "between" being a gas and a plasma is ionized in this way, and it will glow just like the gas in an operating fluorescent tube.

Answer 2

An atom becomes an ion when it either gains or loses an electron, so that it's total charge is either positive (if it lost an electron), or negative (if it gained an electron). Atoms don't necessarily "turn into" an ion. An ion is a positively or negatively charged atom. It is the normal state of the atom. However, if you want to consider it "changed into an ion", it occurs when an atom either gains or losses an electron(s). Atoms gain or lose one or more electrons to exist in a stable state. If the atom gives up an electron, it is positively charged ion. If it gains an electron, it is negatively charged ion.

Answer 3

in general the loss or gain of electrons creates ions, ions with a positive charge are called cations and ones with a negative charge are called anions

lithium loses an ion easily as it has a low ionisation energy. this is the energy required to remove the most loosely bound electron.

lithium loses an electron to become the quite stable lithium cation

Answer 4

The loss or gain of one or more electrons.

Answer 5

Ions are formed when an atom gains or loses electrons. Cations (+) are formed by elements on the left side of the Periodic Table, and anions (-) are formed by elements on the right side.

Answer 6

The formation of positive ions from a mole of gas at STP is called the first ionization energy. The equation is X(g) ---> X^+1(g) + e^-1.
