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-.
There are two s atoms. One shows 0 and other shows+6.
No. Its just S
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.
Sulfur can form the sulfide ion (S2-) and the disulfide ion (S22-) on its own. When combined with oxygen it can form the sulfate ion (SO42-) and sulfite ion (SO32-).
If s represents the length of one side, the area is s * s or s2.

Chemical formula for sulfur is S not S2.
galaxy s2
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.
One swing per second, or 1 full cycle (two swings) per 2 seconds, corresponds to a period of T = 2 s. Using the pendulum equation: T = 2 * pi * sqrt(l/g) 2 s = 2 * pi * sqrt(l/9.81 m/s2) (1 / pi) s = sqrt(l/9.81 m/s2) (1 / pi)2 s2= l/9.81 m/s2 l = 9.81 m/s2 * (1 / pi)2 s2 l ~ 0.994 m
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
A computer in the 1950's would have been the size of a house, so it was both expensive and impractical to own one
s+s2+s+32s2=2s+s2+32s2=2s+33s2I am pretty sure that that is the correct answer.
