S(2-) : sulfide ion
Al(3+) : aluminum ion
The symbol is S2- because to become an ion a sulfur atom gains two electrons and each electron has a 1- charge.
sulfur has 16 electrons with a neutral charge the most common ion formed is the sulfide ion, with a negative 2 charge to get a negative 2 charge, it gains 2 electrons, thus fulfilling the octet rule and acquiring the electron configuration of argon
A sulfur atom becomes a sulfur ion by losing or gaining electrons. If a sulfur atom loses electrons, it becomes a positively charged sulfur ion (sulfur cation). If it gains electrons, it becomes a negatively charged sulfur ion (sulfur anion).
A sulfur atom gains two electrons when it becomes a sulfide ion. This is because sulfur, with its 16 electrons in its neutral state, will achieve stability by gaining two more electrons to fill its outermost energy level and achieve a full octet.
2- Because, to get a full octet, Sulfur gains two electrons to become like Argon, thus it gains a charge of 2-.
The symbol is S2- because to become an ion a sulfur atom gains two electrons and each electron has a 1- charge.
sulfur has 16 electrons with a neutral charge the most common ion formed is the sulfide ion, with a negative 2 charge to get a negative 2 charge, it gains 2 electrons, thus fulfilling the octet rule and acquiring the electron configuration of argon
Nitrogen gains 3 electrons, oxygen gains 2 electrons, sulfur gains 2 electrons, and bromine gains 1 electron when forming ions.
A sulfur atom becomes a sulfur ion by losing or gaining electrons. If a sulfur atom loses electrons, it becomes a positively charged sulfur ion (sulfur cation). If it gains electrons, it becomes a negatively charged sulfur ion (sulfur anion).
Sulfur gains 2 electrons to become stable.
A sulfur atom gains 2 electrons when it becomes a sulfide ion.
The cation S2- is called sulfide ion. It has a charge of -2 and is formed when sulfur gains two electrons to achieve a stable electron configuration.
The element is sulfur with 16 electrons. It gains two electrons to form sulfide ion which has 18 electrons as that of argon.
An ions is formed when an atom gains or loses electrons.
they both gain 2 electrons becoming the anions Oxide and Sulfide, O2- and S2-
A sulfur atom gains two electrons when it becomes a sulfide ion. This is because sulfur, with its 16 electrons in its neutral state, will achieve stability by gaining two more electrons to fill its outermost energy level and achieve a full octet.
Sulfur typically gains 2 electrons to form an ion with a -2 charge.
