In phosphene it gain 4 electrons. Phosphate lose 4 electrons
It can do both. It gains electrons in Phosphene, loses electrons in Phosphate.
Krypton can gain a maximum of 2 electrons to achieve a stable octet configuration, forming the Kryptonide anion. It does not typically lose electrons.
As fluorine is a halogen (the group in which the elements are more reactive as they are one electron lesser than that of the octet configuration)and hence it can only gain electrons.
Fluorine will gain one electron to fill its outer shell and achieve a stable noble gas configuration when forming an ion.
If phosphorus forms a monatomic ion, it gains electrons and form a phosphide ion. More commonly, however, phosphorus forms a polyatomic anion including one or more oxygen atoms. The bonds within these polyatomic anions are covalent, but phosphorus is considered to have a positive oxidation number in such anions, and positive oxidation number corresponds to losing electrons.
Phosphorus wants to gain three electrons to have 8 valence electrons.
Phosphorus can gain up to three electrons to achieve a full outer shell and form the phosphide ion (P3-), or lose up to three electrons to achieve a stable electron configuration and form the phosphorus cation (P3+).
Phosphorus wants to gain three electrons to have 8 valence electrons.
Some atoms lose electrons, some gain electrons, and some share electrons depending on what elements are involved and what compound is forming.
Sulfur can both gain and lose electrons when forming ions. It can gain two electrons to form a sulfide ion (S2-) or lose two electrons to form a sulfide ion (S2+).
It can do both. It gains electrons in Phosphene, loses electrons in Phosphate.
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.
Helium and neon would not be capable of forming an ionic bond because they are noble gases and already have a full valence shell of electrons, making them stable and unlikely to gain or lose electrons.
Beryllium would tend to lose its two electrons when forming a bond because it is easier to lose its two valence electrons rather than gain an additional five in order to obtain a full outer shell.
It will lose 2 to form Sr2+
Krypton can gain a maximum of 2 electrons to achieve a stable octet configuration, forming the Kryptonide anion. It does not typically lose electrons.
Potassium will lose 1 electron to form a 1+ ion.
