    2. Which of the following statements is true?
    A. Metals lose electrons to become cations.

1. Answer;

- Group Number -8

Explanation;

The group number-8 rule states that states that every atom wants to have eight valence electrons in its outermost electron shell. It applies to most atoms of elements in the periodic table. According to the rule, atoms of main-group elements tend to combine in such a way that each atom has eight electrons in its valence shell, giving it the same electron configuration as a noble gas (group-8 elements).

2. Answer;

Metals lose electrons to become cations.

Explanations;

-Ions are charged atoms of elements that are formed by either loosing or gaining electrons. Positively charged ions are called cations while negatively charged ions are called anions.

-Metals forms positively charged ions (cations) by loosing electrons to form a stable configuration while non metals gain electrons to for negatively charged ions (anions).
