Review items 1 to 6 and answer questions a and b: The activities were designed to produce an EX4 research formulation. But not In the process, a mixture is supplied which also contains EX2. looking for features of these substances and their elements, obtained the following information: 1- Element E and element X have, respectively, four and seven electrons valence. 2- The elementary forms of E and X are, respectively, E(s) and X2(g). 3- The melting and boiling points of EX2 are, respectively, -50 and 10 °C. 4- The melting and boiling points of EX4 are, respectively, -70 and 20 °C. 5- For the compounds in question, the binding energy is lower in the situation where central atom (E) hybridization involves fewer orbitals. 6- There is heat release when 1 mol of each compound is formed from the related elementary forms. Based on this information, answer: a) Considering that the binding energy is influenced by electrostatic aspects, explain the difference in the binding energy of the EX. b) Can you know which process involves the highest standard heat of formation at 25°C? If yes, inform and justify; if not, explain why
Electron Affinity
When an element undergoes a chemical reaction, it either gains energy or loses energy. This gain or loss of energy is due to the phenomena that occur at atomic level. During reaction, atoms either gain electrons from other atoms or lose electrons to other atoms, and in that process, energy is produced.
P-Block Elements
Elements which are present on the right side of the periodic table are called p-block elements. In addition to the noble gases, they include the families of boron, mercury, nitrogen, oxygen and fluorine. These elements have diverse real-life implementations that we regularly experience around us.
Metals and Non-metals
The periodic table is composed of metals, semi-metals and nonmetal elements. The physical and chemical properties of metals and nonmetals differ from each other. The study of metals and nonmetals will help one to understand the appropriate application of the particular element.
