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 do you write a formula for the compound that forms from each pair beryllium and iodine?
To write the formula for the compound formed from beryllium (Be) and iodine (I), you first determine the charges of each element. Beryllium has a +2 charge as it is an alkaline earth metal, while iodine has a -1 charge as a halogen. To balance the charges, you need two iodine ions for each beryllium ion. Thus, the formula for the compound is BeI₂.
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 are 4 rules for writing ionic compound formulas for those involving a multivalent metal?
Determine the charges of the ions involved. Balance the charges to determine the ratio of ions needed in the formula. Use Roman numerals in parentheses to indicate the charge of the transition metal. Crisscross the charges to write the formula with the lowest whole number ratio of 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.

Is barium hydroxide an ionic or molecular compound?
Barium hydroxide is an ionic compound because it is composed of a metal (barium) and a non-metal (hydroxide ion). Ionic compounds are formed by the transfer of electrons from the metal to the non-metal.
What is the binary ionic compound for SrBr2?
The binary ionic compound for SrBr2 is strontium bromide. It is formed by the combination of the metal strontium (Sr) and the non-metal bromine (Br), where strontium has a charge of +2 and bromine has a charge of -1.
What is the ionic compound for beryllium oxide?
The ionic compound for beryllium oxide is BeO. Beryllium is a metal with a 2+ charge, and oxygen is a non-metal with a 2- charge. When they combine, they form a stable ionic compound with a 1:1 ratio of beryllium to oxygen ions.
Is aluminum carbide ionic?
Yes, aluminum carbide is an ionic compound. Aluminum is a metal and forms cations with a charge of +3, while carbon is a non-metal and forms anions with a charge of -4. When they combine, they form an ionic compound with the formula Al4C3.
