It can lose 1.
Aluminum will lose 3 electrons to form Al3+ ion.
Nitrogen can gain 3 electrons to achieve a full outer shell with 8 electrons, or lose 5 electrons to achieve a stable electron configuration similar to the noble gas neon.
Sulfur, with its 6 valence electrons, will gain 2 electrons to achieve a stable octet configuration, resulting in a charge of -2.
Phosphorus wants to gain three electrons to have 8 valence electrons.
Potassium will lose 1 electron to form a 1+ ion.
Se will gain electrons
Silicon (Si) can gain or lose 4 electrons. It can either gain 4 electrons to have a stable octet configuration or lose 4 electrons to achieve a stable configuration.
it will lose 3 electrons
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.
45
It will lose 2 electrons.
Silicon gains 4 electrons.
Phosphorus wants to gain three electrons to have 8 valence electrons.
5s orbital
Rubidium typically loses an electron to achieve a stable electron configuration, forming a 1+ cation. This means that rubidium gains no atoms; instead, it loses an electron to become a positively charged ion.
Aluminum will lose 3 electrons to form Al3+ ion.
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+).
