The formula for a chromate ion is CrO4-2, and its charge is -2.
The charge is minus 2.
The valency of the chromate ion is 2-. This means that the chromate ion has a charge of -2.
The symbol for a magnesium ion is Mg^2+. The superscript 2+ indicates that the magnesium ion has a positive charge of 2.
Iodine typically forms a negatively charged ion (anion) with a charge of -1. Therefore, the correct symbol for an iodine ion would be I-.
The symbol is S2- because to become an ion a sulfur atom gains two electrons and each electron has a 1- charge.
The formula, including the charge, for a chromate ion is CrO4-1.
The chromate ion has a charge of 2-. Its symbol is CrO42-.
The symbol for a chromate ion is CrO4^2-.
The charge is minus 2.
The valency of the chromate ion is 2-. This means that the chromate ion has a charge of -2.
There is no "symbol for CrO".
Sn(CrO4)2 Tin 4 means that the tin is a cation with a +4 charge. Chromate is a polyatomic ion with the formula (CrO4)-2. Since the tin ion has a +4 charge in this case, and the chromate ion has a -2 charge, there is a 1:2 ratio of tin ions to chromate ions.
Chromate is an divalent anion with formula CrO4-2
The color of chromate ion is yellow.
the symbol of ion is base on the lemement that you are trying to fin out
The symbol for the antimonous ion is Sb3+, indicating that it has a +3 charge.
The symbol of a monatomic ion is the elemental symbol of the element followed by a superscript representing the charge of the ion. For example, Na+ represents a sodium ion with a +1 charge.
