None, it is a noble gas.
Phosphorus will gain 3 electrons to form an ion with a 3- charge (P3-). This is because phosphorus has 5 valence electrons and needs to achieve a stable electron configuration like a noble gas. By gaining 3 electrons, phosphorus can achieve the electron configuration of argon.
Yes, metallic elements are more likely to lose electrons than nonmetallic elements. This is because metallic elements have fewer valence electrons and their atomic structure makes it easier for them to lose electrons to achieve a stable electron configuration. Nonmetallic elements typically gain electrons to achieve a stable electron configuration.
Boron has 3 valence electrons, gold has 1 valence electron, krypton has 8 valence electrons, and calcium has 2 valence electrons. Valence electrons are the electrons in the outermost energy level of an atom.
None.Calcium loses 2 electrons to form an ion.
Calcium would need to lose 2 electrons to have 8 valence electrons. This is because calcium has 2 valence electrons in its outer shell, and by losing these 2 electrons, it can achieve a stable octet configuration like the noble gas argon.
Bromine (Br) has 35 electrons, while Krypton (Kr) has 36 electrons. To have the same electron configuration as Krypton, Bromine would need to lose one electron.
Se will gain electrons
It can't. Krypton is a noble gas, which means that all of its valence shells are filled with electrons. It doesn't want to be overfilled, nor does it want to be missing any. Though there are laboratory experiments making some types of ions, but it is very difficult and quick. You won't be seeing any ions of krypton made naturally.
Strontium, a group 2 element, will lose 2 electrons to attain a noble gas configuration because it will achieve a stable electron configuration similar to the nearest noble gas, which is krypton. Strontium has 38 electrons in its neutral state, while krypton has 36 electrons. By losing 2 electrons, Strontium becomes Sr2+, and its electron configuration is similar to krypton.
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.
Krypton is a noble gas and need not lose electrons. It is already stable.
