When a chemical bond is formed the constituent atoms acquire the valence electron configuration of noble gases called?
When a chemical bond is formed, the constituent atoms acquire the valence electron configuration of noble gases called the octet rule or the stable electron configuration. This is achieved by sharing, gaining, or losing electrons to attain a full outer shell of electrons, similar to noble gases.
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.
Atoms attain the same electron configuration as of noble gases by?
Atoms can attain the same electron configuration as noble gases by either gaining, losing, or sharing electrons to achieve a full outer shell (valence shell) of electrons. This allows the atom to achieve stability similar to the noble gas 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.
How does potassium and fluorine atoms change their electron configuration to obain a noble gas structure?
Potassium can lose one electron from its outer shell to achieve a stable electron configuration similar to argon. Fluorine can gain one electron to fill its outer shell and attain a stable electron configuration like neon. In both cases, the atoms are trying to achieve a full valence shell and become stable like the nearest noble gas.
What is the formula of the most stable oxygen of francium?
The most stable oxidation state of francium is +1. Francium readily loses its single valence electron to attain a stable electron configuration similar to the noble gas configuration of cesium.
When a chemical bond is formed the constituent atoms acquire the valence electron configuration of noble gases called?
When a chemical bond is formed, the constituent atoms acquire the valence electron configuration of noble gases called the octet rule or the stable electron configuration. This is achieved by sharing, gaining, or losing electrons to attain a full outer shell of electrons, similar to noble gases.
How many electrons must be gained or lost for calcium to attain a noble-gas electron configuration?
Calcium's electron configuration is [Ar] 4s2. To attain a noble gas configuration, calcium must lose 2 electrons to have the same electron configuration as argon, 4s2 3d10.
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.
What is the difference between a stable and unstable electronic configuration?
Stable electronic configuration is when the valence shell of an element is completely filled (8 electrons) whereas unstable electronic configuration is when the valence shell of an element is not completely filled
How many electrons does a phosphorus atom gain in an ionic bond?
A phosphorus atom typically gains three electrons to achieve a stable electron configuration in an ionic bond. This allows it to attain a full outer valence shell with eight electrons, similar to the electron configuration of a noble gas.
How many electrons must be gained or lost for Iodine to achieve a noble gas electron configuration?
Iodine, located in Group 17 of the periodic table, has 7 valence electrons. To achieve a noble gas electron configuration (like Xenon), it must gain 1 electron to fill its valence shell and attain stability.
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.
Atoms attain the same electron configuration as of noble gases by?
Atoms can attain the same electron configuration as noble gases by either gaining, losing, or sharing electrons to achieve a full outer shell (valence shell) of electrons. This allows the atom to achieve stability similar to the noble gas configuration.
Why does bromine make a -1 ion?
Bromine can form a -1 ion by gaining one electron to achieve a stable electron configuration. This allows bromine to attain a full outer electron shell, similar to the electron configuration of a noble gas, making it more stable.
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.

Why do group 17 elements typically form a negative ion?
You mean group VII of the periodic table? Group VII elements are known as halogens and they form -1 ions readily is as they only require 1 more electron to obtain full electronic configuration. They all lack 1 valence electron in their valence shells. Full electrion configuration means that there aren't any valence electrons.
