Sodium atoms have 11 electrons in 3 energy levels, 1st has 2, 2nd has 8, 3rd has 1. When it loses 1 electron the 2nd level is now the outer level and thus follows the octet rule for stability. Chlorine atoms have 17 electrons in 3 energy levels, 1st has 2, 2nd has 8, 3rd has 7. When it gains 1 electron the 3rd level is still the outer level and now has 8 electrons thus follows the octet rule for stability. Na in losing an e- becomes positively charged. Cl gains an e- and becomes negatively charged. The oppositely charged ions attract each other into a crystal lattice forming ionic bonds.
Charged. For example sodium metal reacts with chlorine to produce sodium chloride. This reaction produces two atoms with an octet, sodium which has lost one electron and chlorine which has gained one. The sodium atom is now positively charged, and is called a sodium ion and the chlorine negatively charged and is called a chloride ion.
Boron And Berylium
When sodium loses its single valence electron, it achieves the noble gas configuration of neon, which is an octet.
look for it on the chemistry book, and don't be lazy!Covalent bonding is all about "sharing electrons" so the two elements share electrons (which forms a covalent bond) in order to complete or help complete their octet.
Sodium has one valance electron to donate so that it can complete it's octet. Xenon has a complete octet of eight electrons. So, sodium is more likely to form chemical bonds.
Sodium chloride (NaCl) is an ionic compound. Bonding that occurs between a metal and a non-metal are generally ionic bonding, which bonding between non-metals are always result in the formation of covalent bonds. The sodium atom preferentially loses its single valence electron, which gives it a +1 charge. On the other hand, to achieve octet structure, the chloride atom gains an electron to result in an -1 charge. As such, the 2 ions attract each other and bond to form an ionic compound.

no it does not follow octet rule
Sodium has 1 electron to "donate" and chlorine has space to "accept" 1 electron, so this electron transfer occurs and both have a stable octet electron configuration
Boron And Berylium
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.
Sodium atoms lose one electron in order to obtain an octet. Hence, sodium ions have a 1+ charge.
When sodium loses its single valence electron, it achieves the noble gas configuration of neon, which is an octet.
Atoms gain stability by bonding. This is usually due to achieving a noble gas configuration, also called an octet, as a result of bonding.
Two electrons are needed to fill the outer shell of a sodium atom. The outer shell for sodium is the 3s sublevel. A neutral sodium atom has one electron in its 3s sublevel. Since atoms undergo chemical bonding in order to gain a noble gas electron configuration, called an octet, sodium atoms will lose their single 3s electron, becoming sodium atoms with a 1+ charge. By doing this, sodium ions become isoelectric with the noble gas neon, and achieve an octet, becoming stable.
The octet rule is a rule in chemistry where elements want to form bonds to attain 8 electrons in their valence shell. An example of this would be sodium chloride. Bonds that don't have 8 electrons in their valence shell don't follow this rule
