Learning Task No. 2: Using the Periodic Table of Elements, determine the ele- ments asked in each guide question. Write your answer in your notebook.
Guide Questions:
1. Which elements are likely to lose electrons?
2. Which elements are likely to ain electrons?
3. Which type of elements are likely to have no electrical charge at all?

Explanation:

1 metal they are likely to lose an electron

2non metals

3 Nobel gases because they are not reactive with stable valance number

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
