Radium lose two electrons, the cation is Ra2+.
The ionisation energy required to lose four electrons is generally very high. Hence carbon doesn't lose four electrons.
Actinides and lanthanides lose electrons and form cations.
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.
Potassium will lose electrons when reacting with bromine. Potassium is a metal and tends to lose electrons to achieve a stable electron configuration, while bromine is a nonmetal that tends to gain electrons to achieve a stable electron configuration.
Lose electrons is oxidation. To gain electrons is reduction.
Atoms of metallic elements tend to lose electrons to form positively charged ions. This is because metallic elements have few electrons in their outer shells, making it easier for them to lose electrons and achieve a stable electron configuration.
Polonium can lose two or four electrons.
Uranium loose electrons becoming a cation.
Radium lose two electrons, the cation is Ra2+.
The ionisation energy required to lose four electrons is generally very high. Hence carbon doesn't lose four electrons.
it will lose 3 electrons
Actinides and lanthanides lose electrons and form cations.
When atoms lose electrons cations are produced.
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 loses electrons
Potassium will lose electrons when reacting with bromine. Potassium is a metal and tends to lose electrons to achieve a stable electron configuration, while bromine is a nonmetal that tends to gain electrons to achieve a stable electron configuration.
