Sodium loses its one valence electron to become Na+
When a sodium atom loses a valence electron, it becomes a positively charged ion called a sodium ion (Na+). When a sodium atom gains a valence electron, it becomes a negatively charged ion called a sodium ion (Na-).
if a neutral atom donates an electron it will gain a positive charge. This is due to electrons having a negative charge.
The transfer of an electron between a sodium atom and a chlorine atom occurs because sodium has one electron in its outer shell that it wants to lose to achieve a more stable electron configuration, while chlorine has seven electrons in its outer shell and can gain one from sodium to complete its outer shell and achieve stability by forming a full octet. This transfer of electrons results in the formation of sodium chloride, an ionic compound.
An atom becomes an ion when it gains or loses an electron. Remember, the elements are trying to gain the properties of a noble gas (full electron shells e.g. 2,8,8..). So Sodium has 11 protons (therefore it must have 11 electrons) and only 2 electrons can fill up the first energy level. Then the remaining 9 electrons must be placed into energy levels. The second energy level can only hold 8 electrons, so the additional electron must be placed into an energy level on its own. It has the electronic structure 2,8,1. When it loses its electron to an element like Flourine, Sodium becomes a positive ion and the fluorine which has gained the electron becomes negative.
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.
When a sodium atom loses a valence electron, it becomes a positively charged ion called a sodium ion (Na+). When a sodium atom gains a valence electron, it becomes a negatively charged ion called a sodium ion (Na-).
Negative, assuming that the gain of electrons was an ionizing gain (not just replacing missing electrons)
A sulfur atom gains 2 electrons when it becomes a sulfide ion.
An atom becomes an ion by gaining or losing electrons. When an atom loses electrons, it becomes a positively charged ion (cation) as it has more protons than electrons. On the other hand, when an atom gains electrons, it becomes a negatively charged ion (anion) as it has more electrons than protons.
An atom willreceive a charge when it becomes ionized. If the atom looses one of its electrons (-), then there are more protons (+) and it becomes a+1 charge (positive). If the atom gains an electron, then there are more electrons and it becomes a -1 (negative) charge. It depends on the electrons in the valence level (outer level) to decide if it will gain or lose electrons.
Charged particles that form when atoms gain or lose electrons are called ions. When an atom gains electrons, it becomes a negatively charged ion (anion). When an atom loses electrons, it becomes a positively charged ion (cation).
it becomes a charged ion loose = positive gain= negative
This atom gain two electrons and become an anion.
Sodium loses one electron to form a Na+ ion. Sulfur gains two electrons to form a sulfide ion, S2-.
They form an ionic bond
An atom that has lost or gained electrons is known generally as an ion. More specifically, an atom that has lost electrons becomes a cation. It has a positive charge. An atom that has gained electrons becomes an anion. An anion has a negative charge.
Atoms can lose or gain electrons. When they do, they form charged particles called ions: if an atom loses one or more electrons, it becomes a positively charged ion, I think ;]
