Since Li is a group 1 element with a charge of +1, and there are 2 Li atoms, the overall charge of Li2 in the compound is +2. Therefore, in order for the overall charge of Li2X to be zero (since it is a neutral compound), X must have a charge of -2.
Formula: XF3 where X is the element with which fluorine is bonded
The charge on a chlorate ion is -1. This means that the oxidation state of the chlorine atom in the ion is +7. Cl + O3 = -1 (overall charge) ? + (3 x -2) = -1 Therefore ?= +7 You must remember to put in the sign, even if it is positive.-1 valency
There is no such ion as 'fluorite'. Al the halogen anions end in '----ide' . Notice the 'd' for the 't'. As with all halogen anions (halides) the formula is ' X^(-) ' . 'X' being the given halogen. However the chemical formula for hydrogen fluoride is ' HF '.
The formula mass of the ammonium ion, NH4+, is calculated by adding the atomic masses of the elements in the formula. For NH4+, the atomic mass of nitrogen (N) is 14.01 and the atomic mass of hydrogen (H) is 1.01. Therefore, the formula mass is 14.01 + (4 x 1.01) = 18.05 g/mol.
The charge on ion X in X2O3 is +3. This is because the overall charge of the compound is neutral, and there are three oxygen atoms each with a charge of -2, so the X ion must have a charge of +3 to balance it out.
The charge on ion X in X2O3 is +3. This is because the overall charge of the compound X2O3 is neutral, and there are 3 oxygen atoms each with a charge of -2, so X must have a charge of +3 to balance the charges and make the compound neutral.
In the formula X₂O, the element X is likely a metal that forms a +2 oxidation state. Since oxygen typically has a -2 oxidation state, the two X ions must collectively balance the -2 charge from the oxygen, meaning each X ion has a charge of +1. Therefore, the ion X in this formula is X⁺.

The chemical formula of silver phosphide ia Ag3P. The ion of silver is Ag+.
Since Li is a group 1 element with a charge of +1, and there are 2 Li atoms, the overall charge of Li2 in the compound is +2. Therefore, in order for the overall charge of Li2X to be zero (since it is a neutral compound), X must have a charge of -2.
Positive ions are formed when an atom loses one or more electrons. The formula for a positive ion includes the element symbol followed by a superscript indicating the charge of the ion. For example, the positive ion of sodium is written as Na+ because it has lost one electron.
To find the molar mass of X, we need to calculate the number of moles of X2O3 gas present in the container using the ideal gas law. Once we have the number of moles, we can calculate the molar mass of X by dividing the mass of X in the given amount of X2O3 by the number of moles. This will give us the molar mass of X in grams per mole.
Formula: XF3 where X is the element with which fluorine is bonded
The formula "Li₂X" typically represents a compound where lithium (Li) is combined with another element or group denoted by "X." In this case, "X" could represent an anion or a polyatomic ion. To provide a specific formula, the identity of "X" would need to be clarified, as it can vary widely (e.g., "X" could be fluoride, chloride, or another ion). Therefore, without additional context, the formula remains general.
The charge on a chlorate ion is -1. This means that the oxidation state of the chlorine atom in the ion is +7. Cl + O3 = -1 (overall charge) ? + (3 x -2) = -1 Therefore ?= +7 You must remember to put in the sign, even if it is positive.-1 valency
One oxide ion (O2-) has a charge of -2, while the titanium ion (Ti4+) has a charge of +4. To balance the charges, you would need 2 oxide ions (2 x -2 = -4) for every titanium ion.
