You have learned that not all atoms of an element are the same. Variation in the number of neutrons
results in different isotopes of the element. In this activity we will explore another variation that can take
place—the loss and gain of electrons. The exchange of electrons between atoms is a very common way for
chemical change to take place. We will see it many times throughout the year.

Answer 1

They can be turned into positive ions.

Step-by-step explanation:

neutral atoms can be turned into positively charged ions by removing one or more electrons. Atoms that gain extra electrons become negatively charged. A neutral chlorine atom, for example, contains 17 protons and 17 electrons . By adding one more electron we get a negatively charged Ion with a net charge of negative 1
