How many electrons must Chlorine gain to acquire noble gas arrangement?

1 electron


How can elements acquire a stable atomic structure like that found in a noble gas?

Atoms will gain, lose, or share electrons to match the number of outer shell electrons of a noble gas.


What do other elements do to acquire a noble gas configuration?

Other elements can acquire a noble gas configuration by either gaining or losing electrons. Elements on the left side of the periodic table, such as alkali metals, tend to lose electrons to achieve a noble gas configuration. Elements on the right side of the periodic table, such as halogens, tend to gain electrons to achieve a noble gas configuration. Elements in the middle of the periodic table may gain or lose electrons to acquire a noble gas configuration, depending on the specific element and its properties.


How many electrons must be gained by atoms of CI to form a noble gas arrangement?

Atoms of Cl must gain one electron to form a noble gas arrangement, as it needs a full outer shell with eight electrons to achieve stability, similar to the nearest noble gas, argon.


What Atoms of the halogen family of elements typically gain two electrons when they react?

False; it reacts so that they acquire the electron structure of a noble gas.


What do other elments do to acquire a noble gas configuration?

Other elements can acquire a noble gas configuration by gaining or losing electrons to achieve a full outer electron shell, similar to that of a noble gas. This can be done through forming chemical bonds with other elements or ions in order to stabilize their electron configuration.


How many electrons does As to gain noble gas configuration?

it should gain 3 electrons


What gases do not gain electrons?

Noble gases


What is special about the arrangement of electrons in the noble gases?

Noble gases have a full outer electron shell, making them stable and chemically inert. This arrangement gives them little tendency to gain, lose, or share electrons with other atoms, making them nonreactive under normal conditions.


Metals tend to gain electrons to attain the electron configuration of noble gases?

Ions that are formed when metals gain electrons are called anions. This process allows metals to achieve a stable electron configuration by filling their outermost energy level, similar to noble gases.


How many electrons does nitrogen gain in order to achieve a noble gad electron configuration?

nitrogen has 5 valence electrons. It should gain 3 electrons to achieve a noble gas configuration.


How many electrons do all halogen family elements need to gain in order to attain a noble gas configuration?

All halogen family elements need to gain 1 electron to attain a noble gas configuration. This is because noble gases have a full outer shell of electrons, which is the most stable configuration in terms of electron arrangement.
