1.Comparing and contrasting:
Think about a neutral magnesium atom. Then think of a magnesium ion with a 2+ charge. How are these two alike? How are they different? Be sure to use the terms proton, neutron, an electron in your answer.

2. Predicting:
Tantalum and tungsten are located next to each other on the periodic table. Do you predict that scientists will discover an element that belongs between them? Why or why not? Use the terms atomic number and proton in your answer.
