Antimony (Sb) has an atomic number of 51 and is located in group 15 of the Periodic Table. To achieve a noble gas electron configuration, antimony typically gains three electrons to form a stable anion (Sb^3-), resembling the electron configuration of xenon. Alternatively, it can lose five electrons to form a cation (Sb^5+), but gaining three electrons is the more common pathway for achieving stability.
The noble gas notation for antimony is [Kr] 4d10 5s2 5p3, where [Kr] represents the electron configuration of krypton (a noble gas) that comes before the electron configuration of antimony.
Calcium loses two electrons to obtain a noble-gas electron configuration.
The noble gas configuration of antimony is [Kr] 4d^10 5s^2 5p^3. This means that antimony has 3 valence electrons in its outermost energy level.
Selenium should gain two electrons and lose six electrons to achieve a noble gas electron configuration.
Aluminum has 13 electrons. To achieve a noble gas electron configuration like neon, aluminum needs to lose 3 electrons to have the same electron configuration as neon (10 electrons). This results in the formation of the Al3+ ion.

Silver (Ag) has 47 electrons. To achieve a pseudo-noble-gas electron configuration, silver would need to lose one electron to achieve a stable electron configuration that resembles a noble gas configuration like argon.
Two electrons
Selenium should gain two electrons and lose six electrons to achieve 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.
Every elements have the electrons of an atom distribution or a molecule in molecular orbitals and it is called electron configuration. The element that can be grouped in the family with above electron configuration is called antimony.
Aluminum has 13 electrons. To achieve a noble gas electron configuration like neon, aluminum needs to lose 3 electrons to have the same electron configuration as neon (10 electrons). This results in the formation of the Al3+ ion.
Chlorine gains 1 electron to achieve the noble gas electron configuration of argon.
Calcium (Ca) has 20 electrons in its neutral state. To attain a noble gas electron configuration (like argon), calcium would need to lose 2 electrons to have the same electron configuration as argon, as argon has 18 electrons.
Barium has 2 electrons in its outer shell. In order to achieve a noble gas electron configuration it needs to lose these 2 electrons. This will leave it with the same electron configuration as Xenon, a noble gas.
