Selenium has 34 total electrons. It has 6 valence electrons.
Selenium can gain 1 electron or loss 2, 4, 6 electrons.
Selenium typically gains two electrons to achieve a stable electron configuration, forming the Se2- ion. Arsenic typically loses three electrons to achieve a Noble Gas electron configuration and forms the As3+ ion.
Selenium and bromine can form an ionic bond, where selenium, a nonmetal, gains electrons to become a negative ion, and bromine, a halogen, loses electrons to become a positive ion.
Selenium has 34 electrons.
Calcium and selenium would likely form an ionic bond, with calcium losing 2 electrons to become a positively charged ion and selenium gaining 2 electrons to become a negatively charged ion.
Selenium can gain 1 electron or loss 2, 4, 6 electrons.
When selenium gains two electrons, it becomes the selenide ion.
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.
Since Selenium is a Chalcogen (meaning it's in group 6A on the Periodic Table), it gains 2 electrons to form an ion with a charge of -2.
Selenium typically gains two electrons to achieve a stable electron configuration, forming the Se2- ion. Arsenic typically loses three electrons to achieve a Noble Gas electron configuration and forms the As3+ ion.
Selenium typically loses 2 electrons to achieve a stable electron configuration. This results in the formation of a 2+ ion for selenium.
Yes it will. Selenium has 6 valence electrons. If it accepts two more electrons to form Se2-, the resulting ion will have octet of electrons in the valence shell and will be stable.
Selenium and bromine can form an ionic bond, where selenium, a nonmetal, gains electrons to become a negative ion, and bromine, a halogen, loses electrons to become a positive ion.
3. Thats what the DAT says. But I think its 2. 3p2
Selenium has 34 electrons.
Selenium ions refer to selenium atoms that have gained or lost electrons to become positively or negatively charged. They can exhibit different chemical properties compared to neutral selenium atoms, depending on the number of electrons gained or lost.
Selenium typically forms an ion with a charge of -2 when it gains two electrons to achieve a stable electron configuration. This forms the selenide ion (Se2-).
