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.
Do metals gain electrons to have full octet?
No, metals tend to lose electrons to achieve a full octet.
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
The octet rule is the tendency to have electrons in the shell after ion formation or bond formation?
The octet rule is the tendency to have eight electrons in the shell after ion or bond formation.. This gives the same configuration as a noble gas.
What are the characteristic forms of Octet Rule?
There are a number of characteristic forms of Octet Rules. These rules for example indicate that sets of 8 must be completed at a time.
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.
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
Is formation of table salt a physical or chemical change?
Formation of NaCl from chlorine and sodium is a chemical process.
What do you mean when you say an atom is electron deficient?
It has incomplete octet (incomplete valence shell) after bond formation.
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.
Why isn't NA2Cl not an accurate representation of an ionic bond between sodium and chlorine?
Because sodium donates an electron to reach its octet stability and chlorine accepts an electron to reach the same octet. So + to - charge results in this formula for that compound. NaCl
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.
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 valence electrons are transferred from the calcium atom to iodine in the formatoin of the compound calcium iodide?
during the formation of calcium iodide,calcium donates two of its +ve ions each to a fluorine atom(2 in number) thereby making its octet and also fulfills the octet formation of each of fluorine atom..
What is rules of significant?
The octet rule is the tendency of many chemical elements to have eight electrons in the valence shell.
