Question

7 fill in the blank 1 point magnesium (mg) will choose your answer... electron(s) to satisfy the octet rule, becoming a choose your answer... ion.

Explanation:

Step1: Analyze magnesium's electron - configuration

Magnesium has an atomic number of 12. Its electron - configuration is 2, 8, 2. To satisfy the octet rule (having 8 electrons in its outer shell), it needs to lose 2 electrons.

Step2: Determine the type of ion

When magnesium loses 2 electrons, it has more protons (12) than electrons (10). So it forms a positively charged ion. A positively charged ion is called a cation.

Answer:

lose; 2; cation
