Which of the following best describes a pair of elements that will form an ionic bond?

An ionic bond forms between a metal and a nonmetal. So, since C and O are nonmetals it cannot be that one. Also, P and Cl are also both nonmetals so it cannot be that one either. That leaves Li and O and Ca and Br. In an ionic bond metals loose electrons and nonmetals gain electrons. Therefore it cannot be Li and O because it states that oxygen, the nonmetal, looses electrons and lithium, the metal, looses electrons. So, the answer has to be Ca and Br because Ca, the metal, looses electrons and Br, the nonmetal, gains electrons.

Marizza181 [45]

The correct option is C.

An atom can be either in the ground state or in an excited state. An atom is said to be in the ground state, if the total energy of its electron can not be lowered by moving one or more electrons into different orbitals. At the ground state, the electrons in the atom have the lowest energy possible and they are stable. On the other hand, an atom is said to be in an excited state, if the energy of its electrons can be lowered by transferring one or more electrons into different orbitals. An atom in an excited state has more energy and is less stable.

inessss [21]

Answer: The pH and pOH of the solution is 1 and 13 respectively and the solution is acidic in nature.

Explanation:

There are three types of solution: acidic, basic and neutral

To determine the type of solution, we look at the pH values.
