Metals are characterized by having a large number of free electrons in their atoms, which explains their main properties. These free electrons move between the atoms of the metals, forming a set of electrons known as the 'sea of electrons', which is responsible for metallic bonding. Which of these statements does NOT apply to this sea of electrons?
Electrons move between the atoms of metals at low speed.
Electrons move between the atoms of metals at high speed.
Electrons have no electric charge.
Electrons are responsible for the transfer of thermal energy in metals.
Electrons are responsible for the transfer of electrical energy in metals.

Question 2:


Consider the formation of the ammonia molecule (NH3) from nitrogen and hydrogen atoms. It is known that nitrogen is an element of group 15 (5A) and hydrogen is of group 1 (1A) of the periodic table. Based on this information and your knowledge of covalent bonds, explain the electronic structure of the ammonia molecule and how the formation of this molecule occurs through covalent bonds. What are the expected physical and chemical properties of ammonia, considering the type of bond that constitutes it?

Question 4:


During the realization of a practical chemistry experiment, a student comes across the unbalanced redox equation: Zn(s) + HNO3(aq) → Zn(NO3)2(aq) + NH4NO3(aq) + H2O(l). The student's challenge is to correctly balance this equation using the smallest possible integer coefficients. After balancing, what will be the sum of the stoichiometric coefficients?
