What is the oxidation number for the element found in group 15?
The oxidation number for the element in group 15 (nitrogen group) is usually -3, as these elements tend to gain 3 electrons to achieve a stable electron configuration.
Which element would have properties most similar to the new element?
The element that would have properties most similar to the new element would be an element that lies in the same group as the new element. Specifically, the element with the most similar properties will lie directly above or below that element in the group.
A member of the same family as oxygen whose most stable ion contains 18 electrons?
The element that fits this description is sulfur. Its most stable ion is the sulfide ion (S2-), which contains 18 electrons. Sulfur belongs to the same group as oxygen on the periodic table (Group 16 or 6A), known as the chalcogens.
Which element group have the most negative electron affinities?
The halogens, specifically the group 17 elements, have the most negative electron affinities. This is because they have a strong attraction for gaining an electron to achieve a stable electron configuration with a full outer shell. Fluorine has the highest electron affinity among the halogens.
What is an atomic group?
Each column going down the periodic table is an atomic group.
Which group of elements are stable?
the most stable element group is the noble gases group
What element is most reactive in the group 7a?
Fluorine (F) is the most reactive element in group 7A (also known as group 17 or the halogens). It has a strong tendency to gain an electron to achieve a stable octet configuration, making it highly reactive.
What is the number of the group in which the element have a stable outer energy level?
group 18
What is the element that would show chemical properties most similar to carbon?
carbon the group 14 element has 6 electrons also called the pseudo stable elctrons as they are half balanced. they are stable elements with moderate electronegativity
Which element in group 16 has unstable isotopes?
Polonium is the element in group 16 that has unstable isotopes. It is a radioactive element with no stable isotopes.
Is the most stable element the most reactive?
No, the opposite of that.
What is the most stable element in a nuclear sense?
The most stable element is any member of group ZERO or eight,they are called inert gases because they do not react,hence,stable.However,helium may be considered because it is in period 1 \having the less nuclear charge.
Is Helium the first element on the periodic table and the most stable element in the universe?
False (Hydrogen has the first position, Helium is the most stable)
What is the oxidation number for the element found in group 15?
The oxidation number for the element in group 15 (nitrogen group) is usually -3, as these elements tend to gain 3 electrons to achieve a stable electron configuration.
Tin has the most stable isotopes of any element How many stable isotopes does it have?
It has 10
What is the element in period one and group 8 of periodic table?
Helium is the element that is placed in period 1 and group 18 of the periodic table. It is inert in nature and hence stable.
Which group 18 element can react with Fluorine?
No group 18 element can react with fluorine under normal conditions, as they have a stable and inert configuration with full valence shells.
