The periodic table is an arrangment of the chemical elements, ordered by atomic number, into families, and by doing so illustrat
es the periodic properties of the elements. Considering the organization of the periodic table, which pair of elements represents a very reactive element and a very non-reactive element? A) Cesium and Neon
B) Silver and Gold
C) Sodium and Chlorine
D) Uranium and Hydrogen
Remember, Neon is a noble gas, also called an inert gas. It does not react really to form compounds. Although chlorine is only one column to the left of neon, it is very reactive and ready forms a salt when combine with sodium. The other elements have similar reactivities to each other. Only Neon is a non-reactive choice.
Francium is an element that melts at room temperature. Francium is a highly reactive element, and only contains one valence electron, which is very ironic in my opinion.
It’s charge was neutral due to the equal number of protons and electrons. when it becomes an ion it loses 3 electrons leaving behind only 10. the answer is 10. the equation is +13 +(-10)=+3
