Sodium Atom

An atom of sodium (Na) donates one of its electrons to an atom of chlorine (Cl) in a chemical reaction, and the resulting positive ion (Na +) and negative ion (Cl −) form a stable ionic compound (sodium chloride; common table salt) based on this ionic bond. Sodium appears as a silvery soft metal that becomes grayish white upon exposure to air. Shipped as a solid or molten liquid. Burns violently with explosions that may spatter the material. Used for making gasoline additives, electric power cable, sodium lamps, other chemicals.

The sodium atom wants to lose an electron and the chlorine atom wants to gain an electron. When the two atoms come together the electron from the sodium atom jumps into the gap in the outer shell of the chlorine atom. However, both ions now have eight electrons in their outer shell.

Subsequently, one may also ask, why does the sodium atom lose an electron quizlet?

Why does a sodium atom become more stable when it loses one valence electron? the sodium atom becomes a positive ion and the chlorine atom becomes neg.

Sodium atomic number and mass

Subsequently, question is, when a sodium atom loses an electron what does it become? 2 Answers By Expert Tutors. It reaches the nearest 'noble gas' configuration, albeit as the cation Na+. Sodium will let that electron go as soon as it can, which is why it generally forms ionic compounds such as NaCl. When sodium atom loses an electron from its outer energy shell, it becomes Na+ ion.


One may also ask, why does an atom lose an electron?

Atoms lose electrons, if an electron gets more energy than then binding energy of the electron. This may be because of a collision with a charged particle or because of absorbtion of a photon. In a metal, there are just other positive charges nearby.

Sodium Group Number

If sodium loses an electron, it now has 11 protons, 11 neutrons, and only 10 electrons, leaving it with an overall charge of +1. It is now referred to as a sodium ion. Chlorine (Cl) in its lowest energy state (called the ground state) has seven electrons in its outer shell.
