Question

the united nations declared the year 2019 as the year of the periodic table. the year 2019 marks 150 years since the discovery of the periodic system of the arrangement of elements which led to the periodic table, mostly credited to dmitri mendeleev. since 1869, scientists have discovered or synthesized a number of new elements which exhibit properties in keeping with the logic of the periodic table. which of the four elements is most likely to form cations in its reactions? a. nh b. ts c. mc d. og

Explanation:

Cations are formed when an atom loses electrons. Metals tend to lose electrons to form cations. Among Nh (Nihonium), Ts (Tennessine), Mc (Moscovium), and Og (Oganesson), Nh is a metal. Metals are more likely to form cations in their reactions due to their relatively low - ionization energies and tendency to achieve a stable electron configuration by losing electrons.

Answer:

A. Nh
