The pseudo-noble gas configuration for calcium is achieved when it loses two electrons to form a Ca2+ ion. This results in the same electron configuration as argon.
Be3P2 is a binary ionic compound formed between beryllium (Be) and phosphorus (P). Beryllium has a 2+ charge, while phosphorus has a 3- charge, so the compound is written as Be3P2 to balance the charges.
The compound formed when magnesium reacts with phosphorus is magnesium phosphide (Mg3P2).
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.
P3- or phosphide ion is formed. it has the same number of electrons as the noble gas, argon
Na+ is the formula of the ion formed when sodium achieves a stable electron configuration.
The calcium ion formed when it achieves a noble-gas electron configuration is Ca2+, as it loses two electrons to have the same electron configuration as argon, a noble gas.
Sodium looses one electron to achieve noble gas electronic configuration.The formula of ion formed is Na+
P3-
Na+ ion.
s2,s2 p6.s1
A covalent bond is typically formed between oxygen and phosphorus. Oxygen and phosphorus can share electrons to achieve a stable electron configuration.
The electronic configuration for phosphorus is 1s2 2s2 2p6 3s2 3p3. When phosphorus gains 3 electrons to form an ion, it becomes a phosphide ion with a 3- charge. The symbol for the phosphide ion is P3-.
P-3 ion is formed with 18 electrons.
Sulfur atoms will gain two electrons in order to achieve a noble gas electron configuration. A sulfide ion has the formula S2-.
