which of the following best describes a pair of elements that will form an ionic bond?\no c and h: hydrogen easily loses electrons, and carbon gains them.\no li and o: oxygen easily loses electrons, and lithium gains them.\no p and cl: phosphorus easily loses electrons, and chlorine gains them.\no ca and br: calcium easily loses electrons, and bromine gains them.
Answer
Brief Explanations:
Ionic bonds form between a metal and a non - metal where the metal donates electrons and the non - metal accepts them. Calcium (Ca) is a metal and bromine (Br) is a non - metal. Calcium has 2 valence electrons and easily loses them to achieve a stable electron configuration. Bromine has 7 valence electrons and easily gains 1 electron to achieve a stable octet. In the other options, C and H form covalent bonds, Li is the metal that should lose electrons not O, and P and Cl also form covalent bonds.
Answer:
Ca and Br: Calcium easily loses electrons, and bromine gains them.
