1)How many protons and electrons are in a sulfate ion SO4^2- ?

I know the answer is 48 protons and 50 electrons but i do not know how to get this from the ion.

2) What is the charge on a sulfide ion?

The answer is -2 but im not sure why. Is sulfide always -2?
Answered by bobpursley
electrons in ions=protons minus charge
here , electrons=50-(-2)=52

sulfide is always -2. Memorize it.

sulfide, sulfite, and sulfate ion are -2

I know the answer for protons is 45 and electrons 50 but i do not understand where that came from
Answered by DrBob222
What's the atomic number of S? 16?
What's the atomic number of O? 8?
16 + (4*8) = 48

As u know about the no of electrons then, To find charge in coulumb in one sulphate ion. just do this - charge present on sulphate ion ie- (2 cross charge present in an electron(1.6 cross 10 to the power -19.)

Hi DrBob222, how the electron became 50?
Answered by muhammad
the total number of electrons in sulphate ion are 32
Answered by alpha
atomic no of sulphur =16
atomic no of oxygen=8
so4^-2
so 16+8(4)+2=50

What a silly question 'Eunji'

Anyone please calculate the number of protons in 24 gram of SO4^2- at STP
Answered by AD jhä
Because it have 48 electron and charged is -2
So total electron= 48+2=50
Hence 50 electron in so4
Answered by manmohan
total no of electron is 50 as 16+32+2
total no of proton is 48
total no of neutron is 48

100 because ik it is 100
