Is sodium or argon more reactive and why?
Argon has completely filled valence orbitals and hence is unreactive. Sodium has one valence electron. If sodium loses this electron it will attain the stable electron configuration of the nearest noble gas (argon) and hence is reactive.
Why the metal is very reactive?
Metals , generally, have electronic configuration: with outermost electron having 1,2 or 3. Since, they can easily attain noble gas configuration to attain stability; they readily loose electron.
How many electrons for Aluminum to achieve a noble gas electron configuration?
Aluminum needs to lose 3 electrons to gain a noble gas electron configuration.
What is octet configuration?
Octet configuration refers to how elements generally prefer to form bonds so as to attain an octet configuration, i.e. have 8 electrons in their valence shell. For example, chlorine (Cl) is from Group VII and has 7 valence electrons. It will gain one electron (eg from sodium which loses one electron to form Na+) to form Cl-, which has 8 valence electrons and so fulfills the octet rule and is stable. The electronic configuration of sodium is 2.8.1 (if you're in secondary school), or 1s2,2s2,2p6,3s1 (more advanced). So by losing one electron to form Na+, sodium also attains octet configuration.
When an aluminum atom reacts so as to attain a noble gas electron confuration?
aluminium should lose three electrons to attain noble gas configuration
Is sodium or argon more reactive and why?
Argon has completely filled valence orbitals and hence is unreactive. Sodium has one valence electron. If sodium loses this electron it will attain the stable electron configuration of the nearest noble gas (argon) and hence is reactive.
How is the electron configuration of Sulfur consistent with the formation of Na2S and SF6?
Sulfur has six valence electrons and can therefore attain an inert gas configuration in two different ways: by accepting two electrons to attain the electron configuration of argon or donating or sharing six electrons to attain the electron configuration of neon. In combination with the much less electronegative element sodium, sulfur accepts one electron from each of two sodium atoms to form the ionic compound Na2S, but in combination with the more electronegative element fluorine, sulfur shares its six valence electrons with each of six fluorine atoms to form six polar covalent bonds with fluorine.
How many electrons does oxygen have to gain in order to achieve a noble-gas electron configuration?
Lithium has one valence electron. It is much easier for an atom to lose one electron than gain seven more. Lithium looses this one electron to achieve a full outer shell (the next inside shell is full).
Why the metal is very reactive?
Metals , generally, have electronic configuration: with outermost electron having 1,2 or 3. Since, they can easily attain noble gas configuration to attain stability; they readily loose electron.
How many electrons for Aluminum to achieve a noble gas electron configuration?
Aluminum needs to lose 3 electrons to gain a noble gas electron configuration.
Why group 17 elements are strong non metals while group 1 elements are strong metals?
All elements tend to react with other elements so as to attain a noble gas electronic configuration in their ions, because such a configuration usually has the lowest energy for a particular atom or ion, other factors being equal. The drive to form such an ion is strongest when the electron configuration of an elemental atom differs from the closest noble gas configuration by only one electron, and this criterion is true for both group and group 17 elements: Group 1 elements can attain a noble gas electron configuration by donating one electron to another atom, and Group 17 elements can attain a noble gas configuration by accepting one electron, thereby filling their valence shell.
What is octet configuration?
Octet configuration refers to how elements generally prefer to form bonds so as to attain an octet configuration, i.e. have 8 electrons in their valence shell. For example, chlorine (Cl) is from Group VII and has 7 valence electrons.

The electronic configuration of sodium is 2.8.1 (if you're in secondary school), or 1s2,2s2,2p6,3s1 (more advanced). So by losing one electron to form Na+, sodium also attains octet configuration.
Why these iodine form an ion with a charge of -1?
iodine has 7 electrons in the valence shell. and needs one more electron to attain stable noble gas configuration. So it gains one electron and forms iodide ion with charge of -1.
How many electrons does a silver atom lose to become a silver ion?
The electronic configuration of silver is [Kr]4d105s1. If it loses 1 electron then it will have completely filled d orbitals as its valence orbitals and is stable. It will never attain the electronic configuration of noble gas.
How can valence electron be determined?
actually valency is the combining capacity of atoms so to attain stable configuracy the lose or gain electrons for example chlorine has configuration of 2,8,1 so in order to attain stable configuracy they lose 1 electron.THIS is why we say chlorine has -1 as valency
How many electrons would a neutral atom of nitrogen need to lose in order to have a full valence electron shell?
Since nitrogen is a non-metal with five electrons in its valence shell, it will gain three electrons to attain a stable electronic configuration. So its valency is -3.
Is the elecron configuration of an atom related to its tendency to give up or gain electrons during a chemical reaction?
Yes. If there are 1 to 3 valence electrons in an atom, then generally those elements will lose these electrons to attain noble gas configuration. If there are 5 to 7 valence electrons, then generally those elements will gain electrons to attain noble gas configuration.
