The number of protons of an element does not change when it undergoes a chemical change. It is the number of electrons that changes. Sulfur has 16 protons, and so does the sulfide ion. However, sulfur has 16 electrons, while the sulfide ion (S2-) has 18 electrons.

∙ 9y ago16; that is the atomic number, and the number of protons in the stable form.
S2- has a total of 18 electrons, with 8 electrons in the valence shell

The proton number of S is 16, O is 8.
Protons in Sulfate: 16 + 8 + 8 + 8 + 8 = 48.

How many valence electrons does S2- have?
8 valence electron
The acceleration due to gravity on earth is?
9.81m/s2 or -9.81m/s2 depending how you look at the problem
What are the units for the slope of a velocity-time graph?
Force, in Newtons, can be expressed as Kg*m/s2. Acceleration can be expressed as m/s2. If you divide it out, you get:= N / (m/s2)
Is joule per kilogram equal to meter per second?
Joule is newton-meter, newton is kg m/s2. Therefore: J/kg = Nm/kg = kg m2/s2 kg = m2/s2. So, the answer is no.
One newton is the force that can give a mass of 1 kg an acceleration of?
1 [N] = 1 [kg] * 1 [m/s2]. Answer: an acceleration of 1 [m/s2].
What is the symbol for an ion with 16 protons 16 neutrons and 18 electrons?
S for sulfur because the number of protons tells you the atomic number with is 16 and 16 is sulfur. The electrons means it is an ion with two more electrons than protons. The neutrons have no charge but add mass to the element.
What is the name given to s2?
