Is sodium chloride stable or reactive?
Sodium combines with water in an explosive reaction. Chlorine (Cl) is a halogen; it is a highly reactive element that readily gains an electron to fill its outermost shell. Sodium and chlorine, two highly reactive elements, combine to form the stable compound sodium chloride (ordinary table salt).
How does sodium and chlorine become stable?
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.
Why is sodium chloride more stable than the reactants?
Moreover, the standard enthalpy of formation of NaCl is -411.12 kJ/mol. So this is an exothermic reaction. By losing this much energy per mol of molecules formed, it gains stability compared to its original elements. Less potential energy means more stability.
Is sodium chloride more or less stable than the reactants?
The chemical properties of an element are based on the number of electrons in the outer shell of its atoms. For example, the metal sodium will react violently with the gas chlorine, but once the elements form the compound sodium chloride (table salt) they are very stable due to the stable electron configuration.
Why are ions more stable than atoms?
Why ions are more stable than atoms Thus they are either positively or negatively charged. The atoms do not have completely filled outermost shell . So they lose or gain electrons to attain noble gas configuration and thus stability. Thus the ions are more stable as against the atoms.
Why do sodium and chlorine become bonded?
Because of the propensity of sodium to lose an electron and of chlorine to gain an electron, the elements are well suited to bond with one another. This transfer of electrons results in the formation of the ionic bond holding Na+ and Cl– together.
Is sodium chloride NaCl a stable compound?
Table salt, also known as sodium chloride or NaCl, is one of the best-known and most studied chemical compounds. It crystalises in a cubic unit cell and is very stable. Its chemical composition is simple – one sodium atom (Na) and one chlorine atom (Cl). Or at least that’s true under ambient conditions.
Is the product of the reaction sodium chloride more or less stable than the reactants sodium metal and chlorine gas )? Explain?
Most atoms tend to lose or gain electrons in order to achieve noble gas stability. For example, the metal sodium will react violently with the gas chlorine, but once the elements form the compound sodium chloride (table salt) they are very stable due to the stable electron configuration.
Why are ions stable?
Why ions are more stable than atoms On the other hand ions are formed when atoms lose or gain electrons . So they lose or gain electrons to attain noble gas configuration and thus stability. So ions have noble gas configurations and atoms don’t. Thus the ions are more stable as against the atoms.
When Na+ and Cl unite to form the compound sodium chloride the compound that is formed is?
NaCl
The formula for table salt is NaCl. It is the result of Na+ ions and Cl- ions bonding together (Figure 4.3. 3). If sodium metal and chlorine gas mix under the right conditions, they will form salt.
Is Salt a stable compound?
Table salt, also known as sodium chloride or NaCl, is one of the best-known and most studied chemical compounds. It crystalises in a cubic unit cell and is very stable. Its chemical composition is simple – one sodium atom (Na) and one chlorine atom (Cl).
Why is NaCl stable in nature?
Why is sodium chloride NaCl stable? Sodium chloride (NaCl) is an ionic compound made of sodium (Na) and chlorine (Cl). Sodium readily loses the electron from its outer shell as a full outer shell is more stable. Chlorine accepts this electron to gain a full outer shell, also to gain a more stable noble gas structure.
What happens when sodium chloride dissolves in water?
When dissolved in water, the sodium chloride framework disintegrates as the Na+ and Cl− ions become surrounded by the polar water molecules. These solutions consist of metal aquo complex with the formula [Na(H2O)8]+, with the Na–O distance of 250 pm.
What is the composition of NaCl?
Sodium chloride (NaCl) consists of sodium (Na+) and chloride (Cl-) ions. Add a few drops of an aqueous solution of silver nitrate or AgNO3 (which is colourless) to an aqueous solution of sodium chloride or NaCl (which is also colourless).
How many NA are in 100g of sodium chloride?
Sodium chloride. Sodium chloride /ˌsoʊdiəm ˈklɔːraɪd/, commonly known as salt (though sea salt also contains other chemical salts ), is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. With molar masses of 22.99 and 35.45 g/mol respectively, 100 g of NaCl contains 39.34 g Na…
