Se 2-
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.
Yes, selenium needs to gain 2 electrons to achieve an octet configuration because it has 6 valence electrons in its outer shell. By gaining 2 more electrons, selenium can reach a stable electron configuration with 8 electrons in its outermost shell.
An atom of selenium will gain two electrons to form an octet in its valence shell. This will allow it to achieve a stable electron configuration similar to a noble gas.
Group 16 elements have 6 valence electrons and share similar chemical properties, such as forming -2 ions. Oxygen, sulfur, and selenium are nonmetals that commonly form covalent compounds and have a tendency to gain electrons to achieve a more stable electron configuration.
Neutral Carbon atoms contain 6 electrons and 6 protons 2 electrons are found in the 1st electron ring and 4 in the outer ring to reach a stable electron (8 in the outershell) arrangement carbon requires 4 covalent bonds to be formed
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 needs to gain two electrons to achieve a stable electron configuration. By gaining two electrons, selenium will have a complete outer energy level (valence shell), which is the most stable configuration for an atom.
Yes, selenium needs to gain 2 electrons to achieve an octet configuration because it has 6 valence electrons in its outer shell. By gaining 2 more electrons, selenium can reach a stable electron configuration with 8 electrons in its outermost shell.
An atom of selenium will gain two electrons to form an octet in its valence shell. This will allow it to achieve a stable electron configuration similar to a noble gas.
8 valence electrons
Group 16 elements have 6 valence electrons and share similar chemical properties, such as forming -2 ions. Oxygen, sulfur, and selenium are nonmetals that commonly form covalent compounds and have a tendency to gain electrons to achieve a more stable electron configuration.
Helium is stable with 2 valence electrons. It has a full outer electron shell, making it chemically inert and stable.
Molecules or covalent compounds are formed by the sharing of valence electrons.
The element with a stable 2 valence electrons is helium. Helium has a full outer electron shell with 2 electrons, making it very stable and unreactive.
Valence electron are found in the outer shell of an atom. Depending on the number of valence electrons, the atom is more or less stable: fewer => less stable and more => more stable (inert). Stable = less likely to react with other atoms.
No, sulfur has only 6 valence electrons. Atoms with 8 valence electrons are most stable and generally chemically inert.
Atoms become stable when they have a full outer electron shell, which typically means having 8 valence electrons (except for hydrogen and helium, which are stable with 2 valence electrons). This stable configuration is known as the octet rule.
