It gains or loses electrons.
It becomes a sulfur ion with a charge of -2.
A chlorine atom becomes a chloride ion when it gains an electron from a metal atom, such as sodium.
It becomes this ion after the gain of two electrons.
l
It becomes positive.
It becomes a sulfur ion with a charge of -2.
Sulfur is a metal element. There are 16 electrons in a single atom.
A sulfur atom gains 2 electrons when it becomes a sulfide ion.
Two hydrogen atoms to form hydrogen sulphide (H2S) . It is the smell of rotten eggs.
The atom that gains electron becomes an anion. The atom that loses electron becomes a cation.
If an atom loosed electrons then it becomes an ion. The electrical charge in the atom becomes a positive ion.
A chlorine atom becomes a chloride ion when it gains an electron from a metal atom, such as sodium.
it becomes happy!
If you mean, "What elements make up iron sulphide," then they are Iron and Sulphur. Various 'types' of iron sulphide exist, including FeS (iron (II) sulphide), FeS2 (commonly known as pyrite, iron (II) disulphide or fool's gold), and Fe2S3 (iron (III) sulphide).
the atom becomes negatively charged
If the atom loses electrons, the atom becomes positively charged because the number of positively charged protons.
When atomic SULPHUR forms the bond with another atom (or atoms) in which it becomes the ion SULPHIDE, it accepts two electrons from the outer shell of the other atom(s); giving it a relative negative charge. Examples are Iron (II) [old name Ferrous] Sulphide - FeS - or Potassium Sulphide - K2S [ionic potassium has a single positive charge - it donates a single electron when it forms an ionic bond]. (U.K. Sulphur/sulphide = U.S. Sulfur/sulfide!)
