What happens when sodium atom reacts with a chlorine atom?
If sodium metal and chlorine gas mix under the right conditions, they will form salt. The sodium loses an electron, and the chlorine gains that electron. This reaction is highly favorable because of the electrostatic attraction between the particles. In the process, a great amount of light and heat is released.
What happens when an electron is transferred from sodium to chlorine?
When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl-), both ions have complete valence shells, and are energetically more stable. The reaction is extremely exothermic, producing a bright yellow light and a great deal of heat energy.
When a sodium atom reacts with a chlorine atom to form a compound the electron configuration?
Explanation: During this reaction, the sodium loses one electron on its outer shell which then gives it the electron configuration of neon (2-8) and the chlorine gains one electron on its outer shell which then gives it the electron configuration of argon (2-8-8).
When one electron is transferred from a sodium atom to a chlorine atom A pair of ions with what charge is formed?
+ 1 charge
In forming an ionic bond, the sodium atom, which is electropositive, loses its valence electron to chlorine. The resulting sodium ion has the same electron configuration as neon (1s2 2s22p6). It has a + 1 charge, because there are 11 protons in the nucleus, but only 10 electrons around the nucleus of the ion.
When sodium reacts with chlorine to form sodium chloride What are electrons lost by?
When sodium reacts with chlorine, it transfers its one outermost electron to the chlorine atom. By losing one electron, sodium atom forms a sodium ion (Na+) and by gaining one electron, the chlorine atom forms a chloride ion (Cl-). Sodium ion has positive charge whereas chloride ions have negative charge.
When a chlorine atom gains an electron does it become argon?
When chlorine gains an electron to become a chloride ion with a 21 charge, it ends up with the electron arrangement of argon.
What happens when sodium atoms lose electrons?
When sodium atom loses an electron from its outer energy shell, it becomes Na+ ion.
Why does the sodium atom want to lose an electron and why does the chlorine atom want to gain an electron *?
Atoms want to fill their valence shells. They’re most stable (and thus most happy) with a full outer shell. Sodium, chlorine, and oxygen atoms all want outer shells to have 8 electrons. Hydrogen doesn’t have enough shells to require 8, so it’s happy with just 2.
