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.

How does the octet rule explain the formation of a sodium ion?
Na atom ion has an electronic configuration 2,8,1 On losing one electron it forms Na+ cation, with the configuration of 2,8 thereby obeying octet rule.
How many moles are present in 234g of NaCl?
1 mole NaCl = 58.443g NaCl 234g NaCl x 1mol NaCl/58.443g NaCl = 4.00 moles NaCl
How does the octet rule explain the formation of a chloride ion?
The chlorine atom is in group 17 of the periodic table of elements, so it has 10 inner electrons and 7 outer "valence" electrons. In forming the chloride ion, it becomes negatively charged by gaining an additional electron in the outer shell, so the valence electron shell now has 8 electrons, as per the octet rule.
How many grams are in 0.160 mole of sodium chloride?
1 mole NaCl = 58.44g 0.1601mol NaCl x 58.44g NaCl/mol NaCl = 9.35g NaCl
Do metals gain electrons to have full octet?
No, metals tend to lose electrons to achieve a full octet.
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.
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
How does the octet rule explain the formation of a sodium ion?
Na atom ion has an electronic configuration 2,8,1 On losing one electron it forms Na+ cation, with the configuration of 2,8 thereby obeying octet rule.
What is rules of significant?
The octet rule is the tendency of many chemical elements to have eight electrons in the valence shell.
Another word for an 8 piece band?
its called an octet
What happens to the electrons in a formation of an ionic bond?
Example. Sodium, Na, donates an electron to chlorine, Cl because chlorine's electronegativity is much greater than sodium. So, both achieve the octet state this way and as opposite charges attract they are ionically bonded. Na + A cation and Cl - An anion Form. NaCl Sodium chloride.
What is the heat of formation of NaCl?
The standard enthalpy of formation for sodium chloride is -411,12 kJ/mol.
Which acid and base react in formation of salt sodium chloride?
This is the hydrochloric acid and sodium hydroxide:NaOH + HCl = NaCl + H2O
What is the condition for covalent bond formation?
the condition for covalent bond is that both has to be non metal so that they can share their valence electrons to form duplet or octet configuration
