it S2-, because when you add electrons, you are making the atomic radius bigger. In S2-, you add 2 electron, making it bigger.
hope that helped.
The symbol for sulfide, one of the many ions, is S2-.
The oxidation number of S in S2 is -2. Because each S atom carries a charge of -1.
Ferrous is the traditional name of the iron (II) ion. (Fe 2+) The formula for ferrous sulfide is FeS since sulfur has a charge of -2.
The correct formula for a compound combining Al³⁺ and S²⁻ is Al₂S₃. This is determined by balancing the charges of the ions so that they cancel out in the compound.
The ionic formula for Al3+ is Al^3+ and for S2- is S^2-. When these two ions combine, they form the ionic compound Al2S3.
S^2- is larger in size compared to O^2-. This is because sulfur is lower in the periodic table than oxygen, and as we move down a group in the periodic table, the atomic size generally increases.
If s represents the length of one side, the area is s * s or s2.
what is gravitational force acting on sun in our book it was 270 m/s2 but i think it is 27.0 m/s2 *EDIT*: No, it is 274 m/s2. (27 m/s2 is only marginally higher than Jupiter's)

Given: a square with side = s and a circle with radius = s (radius is equal to the length of the side of the square) Areasquare = side squared = s2 Areacircle = pi times the square of the radius = pi times s2 Areasquare : areacircle = s2 : pi s2 = 1 : pi (The ratio is one to pi.)
If s is the length of a side than, by Pythagoras, s2 + s2 = 82So s2 = 82/2 = 32 square units.s2 is the area of the square so the answer is 32 sq units.If s is the length of a side than, by Pythagoras, s2 + s2 = 82So s2 = 82/2 = 32 square units.s2 is the area of the square so the answer is 32 sq units.If s is the length of a side than, by Pythagoras, s2 + s2 = 82So s2 = 82/2 = 32 square units.s2 is the area of the square so the answer is 32 sq units.If s is the length of a side than, by Pythagoras, s2 + s2 = 82So s2 = 82/2 = 32 square units.s2 is the area of the square so the answer is 32 sq units.
S times S would be S2.

Size the size. The 7s is larger. I have the 7 and like it.
s2 means s multiplied by itself. s is a variable which we may or may not know the value of. E.g. if s = 4 then s2 = 4 x 4 = 16
The noble gas that is isoelectronic with S2- is Argon. Both S2- and Argon have 18 electrons.
The area of a square is s2, where s is the measurement of one side. A = 132 = 169cm2.
