it is Ionic because radium is a metal and selenium is a nonmetal or radium is on the left of the stair case and selenium is to the right
Tin (IV) selenide, SnSe2, is a covalent compound. It is composed of nonmetal elements, tin (Sn) and selenium (Se), which typically form covalent bonds by sharing electrons to achieve stability.
Manganese selenide (MnSe) can exhibit both ionic and covalent character depending on the conditions. In general, it is considered to have more covalent characteristics because manganese has variable oxidation states and forms covalent bonds with selenium.
The ionic compound BaSe is called barium selenide.
Aluminum selenide=============
The name of the binary ionic compound for SrSe is strontium selenide.
Tin (IV) selenide, SnSe2, is a covalent compound. It is composed of nonmetal elements, tin (Sn) and selenium (Se), which typically form covalent bonds by sharing electrons to achieve stability.
Radium oxide has never been characterised. As radium is group 2 metal with chemistry like barium, radium oxide is expected to be ionic.
Manganese selenide (MnSe) can exhibit both ionic and covalent character depending on the conditions. In general, it is considered to have more covalent characteristics because manganese has variable oxidation states and forms covalent bonds with selenium.
The ionic compound BaSe is called barium selenide.
Aluminum selenide=============
The name of the binary ionic compound for SrSe is strontium selenide.
Aluminum selenide is an ionic compound. Aluminum being a metal tends to lose electrons, while selenium being a nonmetal tends to gain electrons, resulting in the formation of an ionic bond between the two elements.
The systematic name of this ionic compound is Tin(IV) Selenide.
Nickel selenide
The correct formula is K2Se. It is an ionic compound: potassium selenide.
Radium forms an ionic compound with oxygen known as radium oxide (RaO). In this compound, radium, a metal, donates electrons to oxygen, a nonmetal, resulting in the formation of an ionic bond between them. Radium oxide is a solid compound with high ionic character due to the large difference in electronegativity between radium and oxygen.
