Is rubidium and calcium an ionic compound?
Rubidium (an alkali metal) does not form compounds or ionic bonds with calcium (an alkaline earth metal). The two each form compounds with several of the same elements (e.g. chloride, carbonate, nitrate).
What is the formula for a compound formed between aluminum and sulfur atoms?
The formula for the compound formed between aluminum and sulfur atoms is Al2S3. This is because aluminum typically forms a 3+ cation, while sulfur forms a 2- anion, resulting in a compound with a 2:3 ratio of aluminum to sulfur atoms.
How many electrons does rubidium gain or lose?
Rubidium typically loses one electron to achieve a stable electron configuration. This results in the formation of a +1 cation when rubidium forms an ionic bond.
What is the formula for rubidium plus fluorine?
The formula for rubidium fluoride is RbF. Rubidium typically forms a +1 ion and fluorine typically forms a -1 ion, so they combine in a 1:1 ratio to form a neutral compound.
What type of bond does rubidium and iodine have?
Rubidium and iodine form an ionic bond. Rubidium, a metal, donates an electron to iodine, a nonmetal, resulting in the transfer of electrons from rubidium to iodine to achieve stability. This forms the ionic compound rubidium iodide (RbI).
What is the element name of the cation in the compound CuF2?
The cation is the metal "Cu", otherwise known as the element Copper.
Will bromine and rubidium form and ionic compound?
Yes, bromine and rubidium can form an ionic compound. Rubidium can donate its outer electron to bromine, which can accept the electron to achieve a stable electron configuration. This forms rubidium bromide (RbBr), an ionic compound with rubidium ions and bromide ions held together by electrostatic forces.
Predict the following chemical formula for a compound between Al and S?
The chemical formula for a compound between Al and S is Al2S3. Aluminum typically forms a 3+ cation and sulfur typically forms a 2- anion. To balance the charges, you need two aluminum atoms for every three sulfur atoms.
What happens when an ionic compound forms between sodium and bromine atoms?
When an ionic compound forms between sodium and bromine atoms, sodium donates an electron to bromine, forming Na+ cation and Br- anion. These oppositely charged ions are held together by electrostatic forces to create the ionic compound sodium bromide (NaBr).
When Rubidium has an atomic number of 37 it can lose 1 electron to form an ion what would its charge be?
When Rubidium (Rb) has an atomic number of 37, it has one electron in its outermost shell. By losing this single electron, Rubidium forms a cation with a charge of +1. Therefore, the charge of the Rubidium ion would be +1, commonly represented as Rb⁺.
What is the charge on the cation in the ionic compound CuS?
The ionic compound CuS is made from the ions Cu2+ and S2-, therefore the cation, Cu2+ has a charge of +2.
When does an atom form a compound?
It forms a compound when atoms bond together in a reaction.
