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.
What else can I help you with?
What are selenium ions?
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.
How many electrons must be gained or lost for selenium to achieve a noble gas electron configuration?
Selenium should gain two electrons and lose six electrons to achieve a noble gas electron configuration.
What happens to electrons during ion formation?
During ion formation, electrons are either gained or lost by an atom. When electrons are lost, a positively charged ion forms (cation), and when electrons are gained, a negatively charged ion forms (anion). This process balances the number of protons and electrons in the atom to achieve a stable electron configuration.
What type of chemical bond forms when atoms that have gained or lost electrons are held together by magnetic attraction?
an ionic bond forms
Which takes place during a redox reaction?
Electrons are both gained and lost. Electrons are both gained and lost.

Selenium should gain two electrons and lose six electrons to achieve a noble gas electron configuration.
What type of compound forms covalent bonds?
ions. (atoms that have lost or gained electrons)

Electrons are both gained and lost. Electrons are both gained and lost.
What forms when an atom has lost or gained electrons?
When an atom looses an electron is called "a cation, when gains is called an "anion".
What is gained in a chemical reaction?
Electrons are the ones gained or lost in a chemical reaction. Electrons are gained in oxidation and lost through the chemical reaction known as reduction.
What are Atoms that carry an electrical charge called because they have gained or lost electrons?
Atoms that carry an electrical charge because they gained or lost electrons are called ions. An atom that has lost electrons will be positively charged, and it is called cation. On the other hand, an atom that has gained electrons will be negatively charged, and it is called anion.
How many electrons are lost or gained in Xe?
Xenon (Xe) typically forms compounds by gaining two electrons to achieve a stable electron configuration.
How many electrons will be gained or lost by scandium?
Usually three will be lost.
Are electrons lost or gained during the formation of a negatively charged ion?
They are gained.
