Fluorine attains the electron configuration of neon (the nearest noble gas).
Calcium (Ca) is an alkaline earth metal that typically loses two electrons to achieve a stable electron configuration when forming an ion. This results in the formation of a calcium cation (Ca²⁺). By losing these two valence electrons, calcium attains a noble gas configuration similar to argon.
Sulfur gains two electrons to attain a noble gas configuration, which is the electron configuration of argon. This allows sulfur to have a stable octet of electrons in its outer shell and achieve a more stable electron configuration.
Bromine gain an electron in chemical reactions.
The element with the electron configuration of 2.7 is chlorine (Cl). This configuration indicates that chlorine has 2 electrons in its first energy level and 7 electrons in its second energy level. Chlorine is a halogen and is known for its reactivity, often forming compounds by gaining an electron to achieve a stable octet.
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.

The electrons in the outer shell of an atom are responsible for forming bonds in a molecule. When atoms come together to form molecules, they share, gain, or lose electrons to achieve a stable electron configuration.
Bromine will gain one electron when forming an ion to achieve a full outer electron shell. This will give it a stable electron configuration.
Fluorine gains an electron when forming bonds because it has seven electrons in its outer shell and wants to achieve a stable octet configuration, similar to the noble gas configuration. By gaining one electron, fluorine can fill its outer shell and become more stable.
Bromine typically gains one electron when forming an ion to achieve a stable electron configuration. The electron configuration for a bromine ion is [Kr] 4d10 5s2 5p6, which is the same as that of a noble gas.
Water (H2O) is an example of a covalent molecule. In water, the oxygen atom shares electrons with two hydrogen atoms, forming covalent bonds. Covalent molecules are formed when atoms share electron pairs to achieve a stable electronic configuration.
Sodium gives away one electron to achieve a stable electron configuration, forming a cation with a +1 charge.
It is called the octet rule.
Bromine typically gains one electron to achieve a stable electron configuration in chemical reactions, forming an anion with a charge of -1. This allows bromine to achieve a full outer shell of electrons like the noble gas configuration of krypton.
In potassium fluoride (KF), potassium loses one electron to achieve a stable electron configuration, forming a K+ cation, while fluorine gains one electron to achieve a stable electron configuration, forming a F- anion. The attraction between the positively charged potassium ion and the negatively charged fluoride ion leads to the formation of an ionic bond in KF.
Bromine gain an electron in chemical reactions.
