What is the charge on the metal in the compound M2S3?
The charge is +3
What is the formula for rubidium arsenide?
A little more information is needed. Rhenium is a transition metal, and as such, can have multiple valence states. If an ionic charge is known, for example, +2, then it can be assumed that the formula for the oxide would be RhO. If percent composition by mass is known, for example, 86.5% rhenium by mass, then math can be done to determine the formula of the oxide, which in this case, would also be RhO.
How is the oxidation state of transition metal determined from the chemical formula?
The subscript of the second ion identifies the oxidation state of the transition metal
What metal is a compound?
A metal is a chemical element not a compound.
What rule of thumb is used to determine to charge on non metal ions?
metals generally form positively charged ions
What is the charge on the metal in the compound M2S3?
The charge is +3
Name one metal that is multivalent?
Examples of multivalent metals are lead, iron, tin, mercury and copper. They will be written using Roman numerals. To be multivalent they have to have a valence level of at least three or higher.
How to determine if a solid chemical were an ionic compound or covalent compound?
ionic compounds are a metal and a non-metal joined together in a bond
What charge does the atom have when a metal and a nonmetal meet?
it forms an ionic compound
What is the type of element sulfur?
It is an abundant, multivalent non-metal.

Name the compound written as CuF2?
First, you need to determine the elements in the equation. They are copper and fluorine, respectively. Next, we determine if the compound is ionic or covalent. Remember that a basic ionic cmpd is a metal bonded to a nonmetal, and a basic covalent compount is non-metal-non-metal. Copper is a metal, so the bond is ionic. To name an ionic compound, you have the first part (the metal) written regularly, and the second part (in this case a monoatomic non-metal) is written regularly, but the last part is dropped and replaced with "ide". So far, the name of our compound is Copper fluoride. There is a certain type of metal called a transition metal. These metals, unlike the alkali or alkaline earth metals, have no set charge. Therefore, we must determine copper's charge and indicate it in the name. Balancing the charges: fluoride has a -1 charge. There are two F ions, making the charge of the non-metals -2. The charge must be balanced to 0, which can be done using thie following equation: x + -2 = 0 --> add 2 to both sides, the twos cancel on the right, and we get x = 2. Therefore the charge of the copper ion is 2+. To indicate this in the name, you put the charge in roman numeral form in parenthesis after the metal. The final name is Copper (II) fluoride.
Is MgF an ionic compound or a covalent compound?
MgF2 Magnesium, an alkaline earth metal of 2+ ionic charge and two fluorine, a nonmetal, atoms of 1- charge each form a ionic bond
Why is BaO ionic?
BaO is an ionic compound. You can determine it is ionic because the bond exists between a metal (Ba) and a non-metal (O).
What is the overall charge of an ionic compound?
it is always equal to zero.The overall charge of a formula unit for an ionic compound is zero. The numbers of positive and negative ions are such that the sum of the positive charges and the negative charges is zero.
Is BaI2 an ionice compound?
Yes. An Ionic compound is a compoud composed of a metal and a non metal. Ba is the metal and I is the non-metal. It's written form is Barium Iodide. You are not required to specify the roman numeral because Barium has a non-varying charge (2-).
Is sulphur metal or non metal?
No it's not, it's a multivalent non-metal.http://en.wikipedia.org/wiki/Sulfur
