Will selenium form a 2- ion?
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.
Does selenium need to gain 2 electrons to for an octet?
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.
What will happen to an atom of selenium in order to form a octet?
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.
Oxygen sulfur and selenium belong to group 16 on the periodic table What does this indicate?
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.
What number of valence electrons that carbon has?
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
Will selenium form a 2- ion?
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.
How many electrons does selenium need to lose or gain to 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.
Does selenium need to gain 2 electrons to for an octet?
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.
What will happen to an atom of selenium in order to form a octet?
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.
How many Valence electrons in a stable octet?
8 valence electrons
Oxygen sulfur and selenium belong to group 16 on the periodic table What does this indicate?
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.
What element is stable with 2 valence electrons?
Helium is stable with 2 valence electrons. It has a full outer electron shell, making it chemically inert and stable.
What chemical do valence electrons make when sharing?
Molecules or covalent compounds are formed by the sharing of valence electrons.
What element has a stable 2 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 electrons found where?
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.
Is sulfur outer most shell stable?
No, sulfur has only 6 valence electrons. Atoms with 8 valence electrons are most stable and generally chemically inert.
All atoms become stable when they have how many valence electrons?
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.
