Question

a model of a potassium bromide (kbr) lattice is shown below. a model of potassium bromide represents potassium as purple and bromide as dark red. complete the statement. potassium bromide is held together by ______ bonds. choose 1 answer: a covalent

Explanation:

Potassium is a metal and bromine is a non - metal. Ionic bonds form between metals and non - metals when electrons are transferred from the metal to the non - metal. Potassium loses an electron to form a cation and bromine gains an electron to form an anion, and the electrostatic attraction between these ions holds the compound together. Covalent bonds form between non - metals by sharing electrons, which is not the case here.

Answer:

B. ionic (assuming there is an ionic option not shown in the provided part of the question as the correct answer is ionic and not covalent)
