Yes, your answer is correct. Magnesium (Mg), with an atomic number of 12, is located in Group 2 and Period 3 of the periodic table. So, the correct answer is C. Good job!
To determine the location of magnesium (Mg) on the periodic table, you need to understand its properties, including its atomic number, group, and period.
First, look up magnesium on the periodic table. The atomic number of magnesium is 12, which indicates the number of protons in its nucleus.
Next, determine the group of magnesium. Groups are vertical columns on the periodic table. Magnesium is located in Group 2, also known as the alkaline earth metals. This group consists of metals that are highly reactive and have two valence electrons.
Finally, identify the period of magnesium. Periods are horizontal rows on the periodic table. Magnesium is in Period 3, which means it has three energy levels or electron shells.
Based on this information, we can describe the location of magnesium on the periodic table as Group 2 and Period 3. Therefore, the correct answer is C) group 2, period 3. Good job! Your answer is correct.
