Helium has an atomic number of 2. Is the model of the helium atom above is
showing an ion? Explain why or why not.

Answer:
Yes, the model of the helium atom is showing an ion.
Explanation:
Helium, with an atomic number of 2, should have 2 protons and 2 electrons; however, the model only depicts 1 electron. That means the helium must have lost an electron, making it a +1 charge and an ion.
