Answer

Explanation:

Step1: Analyze calcium (Ca)

Calcium is in group 2, has 2 valence - electrons. It will lose 2 electrons to have a full valence level.

Step2: Analyze fluorine (F)

Fluorine is in group 17, has 7 valence - electrons. It will gain 1 electron to have a full valence level.

Step3: Analyze lithium (Li)

Lithium is in group 1, has 1 valence - electron. It will lose 1 electron to have a full valence level.

Step4: Analyze argon (Ar)

Argon is a noble gas in group 18, has 8 valence - electrons. It already has a full valence level, so it will gain or lose 0 electrons.

Step5: Analyze aluminum (Al)

Aluminum is in group 13, has 3 valence - electrons. It will lose 3 electrons to have a full valence level.

Answer:

A calcium atom (Ca) will lose 2 electrons. A fluorine atom (F) will gain 1 electron. A lithium atom (Li) will lose 1 electron. An argon atom (Ar) will gain or lose 0 electrons. An aluminum atom (Al) will lose 3 electrons.
