How do we know Cl and Na are now stable?

How do we know Cl and Na are now stable?

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. In the process, a great amount of light and heat is released. The resulting salt is mostly unreactive — it is stable.

What happens to the Cl atom when it becomes part of a stable molecule NaCl?

When sodium and chlorine atoms come together to form sodium chloride (NaCl), they transfer an electron. When this happens, the atom is called a positive ion. The chloride ion now has eighteen electrons and seventeen protons, so it’s become a negative ion.

What is more stable sodium atom or sodium ion?

The atom of sodium has one electron in its outermost shell. To achieve a stable electron configuration it has to lose this electron so that all the electron shells are complete. This shows that sodium ions are more stable than the sodium atom, else there would not be a release of heat during the reaction.

What do you think will happen when sodium metal Na and chlorine gas cl2 react to form table salt nacl which atom was reduced?

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.

Why do two sodium atoms need to complete?

Why did it require two sodium atoms to complete the Na2O formula unit? Na has +1 charge and O has -2 charge. You just studied 11 terms!

Why does Na get a change when it forms an ionic bond?

Ionic bonds form when metals and non-metals chemically react. For example, in the reaction of Na (sodium) and Cl (chlorine), each Cl atom takes one electron from a Na atom. Therefore each Na becomes a Na+ cation and each Cl atom becomes a Cl- anion.

Which is more stable between Na and Na+ and why?

Na+ is more stable than Na as Na+ has lost one electron to attain nearest Noble gas configuration of Neon no of electrons = 10 and hence configuration of 2,8. Where as Na has no of electrons =11 and hence electronic configuration of 2,8.

Why sodium atom is unstable but sodium ion is stable?

Sodium (+1) ion has the noble gas configuration, which means their outermost shell are completely filled with electrons. That’s why Sodium ion is not reactive (means stable). The atom of sodium has one electron in its outermost shell.

Why do transition elements not obey the octet rule?

For example, lithium can lose an electron to have a stable configuration in which the valence shell holds two electrons. Due to the presence of a d-orbital, the transition elements do not obey the octet rule.

Why is the Na+ ion more stable than the metallic sodium?

The outermost shell of sodium has one electron. If it loses this electron, the second shell would become the valence shell (which is already filled with 8 electrons). Thus, the Na + ion is more stable than metallic sodium.

How do sodium and chlorine complete their octet?

Both sodium and chlorine share their electron and complete their octet by forming Sodium Chloride (NaCl) as shown below with the help of Lewis dot structure: Na. .:::

What is the octet rule for ionic compounds?

The octet rule reflects the observation that the most stable ions of many elements have eight electrons in their valence shell for gaining the best possible stability. +1 +1. These patterns can be used to predict how elements will combine to form polyatomic ions and compounds.
