What is a reactivity ceris

The reactivity series of metals is a chart listing metals in order of decreasing reactivity. In general, the more reactive a metal is: the more vigorously it reacts with other substances. the more easily it loses electrons to form positive ions (cations)

Hi, There! Your Answer Is Below!

A reactivity series is used to rank the chemical reactivity of a group of metals from most reactive to least reactive.

Explanation:

The reactivity series is a series of metal elements, and sometimes carbon and hydrogen, that is arranged according to their reactivity. A reactivity series is typically a vertically presented model with the most-reactive element placed at the top of the series and the least-reactive element placed at the bottom.

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
