question 1
The electrostatic attraction force is responsible for the union of ions, where electrical charges of opposite signs attract. Speaking at a microscopic level, such attraction between ions ends up producing clusters with well-defined geometric shapes, represented by the following figure:
What is the best definition for this ionic structure and what compound is formed from it?
a) salt / potassium chloride crystals
b) flat-faced crystal / calcium chloride
c) crystalline reticulum / sodium chloride
d) bonding lattice / sodium chlorate
e) double-sided structure / sodium chloride
question 2
Among the alternatives below, mark the one that brings the correct words to complete the statement about the electrical conductivity property of ionic compounds.
Ionic compounds conduct electrical current when dissolved in water or when pure in the state... due to the existence of... with freedom of movement, which can be attracted by..., closing the... ...
a) solid, ions, electrodes, electrical circuit
b) liquid, ions, electrodes, short circuit
c) gas, cations, electrodes, electrical circuit
d) liquid, ions, electrodes, electrical circuit
e) solid, cations, electrons, electrical circuit
