The activity series which metals lose their electrons more easily answer key

In the activity series, the metal that loses their electrons more easily are less reactive compared to metals that forms positive ions. In addition, an activity series is a list of substances in order from most reactive to least reactive and its relative reactivity can be determined by using a number of chemical reaction. Moreover, metals in the activity series need to lose their electrons, or be oxidized or some metals will tend to stay in their neutral state.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.

there is none because earth is stationary and flat.
