Sodium (Na) has 1 electron in the 3s orbital and chlorine (Cl) has 7 electrons in the 3p orbital. Sodium gives away the one electron to Cl, leaving it with 8 electrons (octet) in the 2p orbital (like Neon). The chlorine takes that one electron giving it 8 electrons (octet) in the 3p orbital. The sodium then has a +1 charge, and the chloride ion now has a -1 charge. This is an ionic bond.
What else can I help you with?
In naCL why would CL gain the electron?
Chlorine (Cl) would gain an electron in sodium chloride (NaCl) to achieve a full outer electron shell and attain a stable octet configuration, following the octet rule. By gaining an electron, chlorine becomes a chloride ion with a full outer shell, creating an ionic bond with the sodium cation to form a stable compound.
Which will have the lowest boiling point pure water 0.5 M NaCl aq 1.0 M NaCl aq or 2.0 M NaCl aq?
Pure water will have the lowest boiling point because it does not contain any solute particles to elevate the boiling point. As the concentration of NaCl increases, the boiling point also increases due to an increase in the number of solute particles that disrupt the formation of water vapor. Therefore, 0.5 M NaCl will have a higher boiling point than pure water, followed by 1.0 M NaCl, and finally 2.0 M NaCl will have the highest boiling point.
Write the chemical equation that shows sodium Na and chlorine CI2 combining to form table salt NaC1?
The chemical equation for the formation of table salt from sodium and chlorine is: 2 Na + Cl2 -> 2 NaCl
How many moles are present in 234g of NaCl?
To find the number of moles in 234g of NaCl, divide the given mass by the molar mass of NaCl. The molar mass of NaCl is 58.44 g/mol (sodium = 22.99 g/mol, chlorine = 35.45 g/mol). So, 234g ÷ 58.44 g/mol = 4 moles of NaCl.
What does nacl hcl kscn reaction gives and what is the color of the product?
The reaction between NaCl, HCl, and KSCN does not directly give any colored products. It typically results in the formation of NaSCN (sodium thiocyanate) and KCl (potassium chloride), with HCl acting as a catalyst. The color of the products is usually white or colorless.
Why is an input of energy needed when forming NaCl?
The standard enthalpy of formation for NaCl solid is: -411,12 kJ/mol at 25 0C.
Is formation of table salt a physical or chemical change?
Formation of NaCl from chlorine and sodium is a chemical process.
The octet rule is the tendency to have electrons in the shell after ion formation or bond formation?
Yes, the octet rule states that atoms tend to gain, lose, or share electrons in order to have a full outer shell with eight electrons, which is considered stable. This stability is achieved by achieving the electron configuration of a noble gas.
What are signs for a chemical reaction of NaCl?
For example formation of a precipitate as in the following reaction: NaCl + AgNO3 = AgCl(s) + NaNO3 Silver chloride is a white precipitate.
What is rules of significant?
The octet rule is the tendency of many chemical elements to have eight electrons in the valence shell.
Does PCl2F3 follow the octet rule?
yes PCl3 obey octet rule there are 5 electrons in the valence shell of phosphorous it need 3 electron to complete its octet so it form bond with 3 chlorine after bond formation there are 8 electron in its octet it obey octet rule
Another word for an 8 piece band?
its called an octet
In naCL why would CL gain the electron?
Chlorine (Cl) would gain an electron in sodium chloride (NaCl) to achieve a full outer electron shell and attain a stable octet configuration, following the octet rule. By gaining an electron, chlorine becomes a chloride ion with a full outer shell, creating an ionic bond with the sodium cation to form a stable compound.
What is octate state?
The octet state refers to a configuration in which an atom has eight electrons in its outermost shell, achieving a stable electron arrangement similar to that of noble gases. This concept is central to the octet rule in chemistry, which states that atoms tend to bond in ways that allow them to have eight valence electrons. Atoms often achieve this stability through the formation of covalent or ionic bonds. The octet state is crucial for understanding chemical reactivity and the formation of molecules.
Is NACL ionic or covalent bonds why cant it be covalent bond?
NaCl is formed by ionic bonds because sodium (Na) donates an electron to chlorine (Cl), resulting in the formation of Na+ and Cl- ions that are attracted to each other by electrostatic forces. Covalent bonds involve the sharing of electrons between atoms, which does not occur in the formation of NaCl.
What do you mean by octet and duplet?
In chemistry, the octet and duplet rules are part of electronic configuration. The octet rule is when the outermost shell has 8 valence electrons. The duplet rule is when the outermost shell has 2 valence electrons, e.g. Helium and Hydrogen.
What is the heat of formation of NaCl?
The standard enthalpy of formation for sodium chloride is -411,12 kJ/mol.
