Question

for each atom, determine what process it will undergo when becoming a stable ion. items (5 items) (drag and drop into the appropriate area below) lose 2 electrons lose 1 electron gain 2 electrons lose 3 electrons gain 1 electron categories k al o ca cl

Explanation:

Step1: Analyze potassium (K)

Potassium is in Group 1, has 1 valence - electron. It will lose 1 electron to achieve a stable octet.

Step2: Analyze aluminum (Al)

Aluminum is in Group 13, has 3 valence - electrons. It will lose 3 electrons to achieve a stable octet.

Step3: Analyze oxygen (O)

Oxygen is in Group 16, has 6 valence - electrons. It will gain 2 electrons to achieve a stable octet.

Step4: Analyze calcium (Ca)

Calcium is in Group 2, has 2 valence - electrons. It will lose 2 electrons to achieve a stable octet.

Step5: Analyze chlorine (Cl)

Chlorine is in Group 17, has 7 valence - electrons. It will gain 1 electron to achieve a stable octet.

Answer:

K: Lose 1 Electron
Al: Lose 3 Electrons
O: Gain 2 Electrons
Ca: Lose 2 Electrons
Cl: Gain 1 Electron
