State the number of electrons lost or gained when the following elements form Ions.
S
Express your answer as an integer.
Sulfur is in Group 16 of the periodic table. It has 16 electrons in its neutral state.
To determine the number of electrons lost or gained, we need to consider whether sulfur will gain or lose electrons to complete its valence shell.
To reach a stable electron configuration, sulfur can either gain two electrons to have the same electron configuration as the nearest noble gas, argon (with 18 electrons), or it can lose six electrons to have the same electron configuration as the nearest noble gas, neon (with 10 electrons).
Since gaining two electrons would require more energy than losing six electrons, sulfur is more likely to lose six electrons and form a 2- ion.
Therefore, when sulfur forms ions, it will lose 6 electrons.
To determine the number of electrons gained or lost when an element forms an ion, we need to consider its position in the periodic table.
Sulfur (S) is located in group 16 (also known as Group VI) of the periodic table. Elements in this group have 6 valence electrons.
To become stable, every element aims to achieve a filled outermost electron shell. In the case of sulfur, it needs to either gain 2 electrons to fill its 3rd energy level or lose 6 electrons to expose a filled 2nd energy level.
Since gaining 2 electrons is more favorable, sulfur tends to form an ion with a charge of -2 by gaining 2 electrons. This means that when sulfur forms an ion, it gains 2 electrons.
Therefore, when sulfur forms ions, it gains 2 electrons.
To determine the number of electrons gained or lost when an element forms ions, you need to look at its position in the periodic table and its electronic configuration.
In the case of sulfur (S), we can find it in Group 16 of the periodic table. This means it has six valence electrons.
When an element forms ions, it tends to gain or lose electrons in order to achieve a stable electron configuration. Since sulfur is in Group 16, it tends to gain two electrons to achieve the electron configuration of the nearest noble gas, argon (1s2 2s2 2p6 3s2 3p6). Thus, sulfur will form an ion with a charge of -2, meaning it gains two electrons.
Therefore, the number of electrons gained by sulfur when forming ions is 2.
