Question

Now try the following three examples elements formula name beryllium de beryllium+ BeN2 nitrogen The element beryllium is an Alkaline Earth Metal, which loses two electrons (2+) and nitrogen is in Group V which gains three electrons (3-). It will have the ending "ide". silver carbonate silver + AG2CO3 carbon The element silver is a transition metal, with only one stable ionic state. Carbon is in Group IV, which gains four electrons. cadmium(II) hydride cadmium + сан2 hydrogen The element cadmium is a transition metal, with only one stable ionic state. Hydrogen will gain one electron when reacting with a metal. It will be named "hydride". Submit Answer Incorrect. Tries 2/10 Previous Tries

Answer 1

beryllium has the valency 2 i.e it can looses 2 electrons and forms the Be2+ ion and the nitrogen can gains the 3 electrons and forms the N3- ion and the formula is obtained by getting the beryllium 3 subscript and the nitrogen 2 subscript and the formula is as follows

=> Be₃N₂

silver has the valency 1 i.e it can loose 1 electron and forms the Ag+ ion and the carbon can gains the 4 electrons and forms the C4- ion and the formula is obtained by getting the silver 4 subscript and the carbon 1 subscript and the formula is as follows

=>Ag₄C

cadmium has the valency 2 i.e it can looses 2 electrons and forms the Cd2+ ion and the hydrogen can gains the 1 electron and forms the H- ion and the formula is obtained by getting the Cadmium 1 subscript and the Hydrogen 2 subscript and the formula is as follows

=> CdH₂ or H₂Cd
