First you have to find the overall charge of the C2H3O2. Hydrogen always has to have a +1 charge, and oxygen generally gets a -2 charge. then use the x for the unknown and multiply each charge by the number of the substance.
ex. 2(x) [for the carbon] + 3(+1) [for the hydrogen] + 2(-2) [for the oxygen]= overall charge of the molecule. then find x.
First off, we need to know the number of electrons of all of the constituent atoms in this molecule. Carbon has 6, hydrogen has 1, and oxygen has 8. Therefore, this molecule has 6*2 + 1*5 + 8 + 1 = 26 electrons.
Acetate!!
(side note: Acetate is very commonly referred too as: "CH3COO")
(It is the same thing, just rearranged... just like H2O can become HOH, they are still both water)
The charge is -1.
A single negative charge
the charge of carbon is 0
20
24
Carbon has 4 valence electrons; hydrogen has 1; oxygen has 6. As it is a negative (1) ion, you add 1 valence electron. (4)(2)+(1)(3)+(6)(2)+1=24 valence electrons
There are 7 valence electrons in chlorine atom and 8 valence electrons in chloride ion.
A chloride ion has 18 electrons, giving it a valence of -1.
Iodine atom has 7 valence electrons, whereas Iodide ion has 8 valence electrons.
Three electrons
Carbon has 4 valence electrons; hydrogen has 1; oxygen has 6. As it is a negative (1) ion, you add 1 valence electron. (4)(2)+(1)(3)+(6)(2)+1=24 valence electrons
There are 7 valence electrons in chlorine atom and 8 valence electrons in chloride ion.
A chloride ion has 18 electrons, giving it a valence of -1.
Iodine atom has 7 valence electrons, whereas Iodide ion has 8 valence electrons.
Three electrons
Chlorine has 7 valence electrons. A chloride ion has 8.
A magnesium atom has 2 electrons in its valence shell. A magnesium ion has 8 electrons in its valence shell.
Phosphorus forms P3- ion and it has 8 valence electrons (5 valence electrons from phosphorus and three from the charge).
8
Helium has two valence electrons. O6+ ion (a hypothetical ion) will also have 2 valence electrons.
Halides have 7 valence electrons, but the halide ion, haven gained an electron has 8 valence electrons
Electrons in the outermost shell of an atom/ion are called valence electrons
