Hydrogen atoms and helium atoms are not the same.
True
False

The answer is False (No). All helium atoms have 2 protons in their nucleuses (nuclei). If an atom has only 1 proton it its nucleus, then it is a hydrogen atom. (it behaves like other hydrogen atoms, not like a helium atom.)

FALSE

Explanation:

The answer is False (No). All helium atoms have 2 protons in their nucleuses (nuclei). If an atom has only 1 proton it its nucleus, then it is a hydrogen atom. (it behaves like other hydrogen atoms, not like a helium atom.)

electron microscopy and scanning tunneling microscopes gives us a greater understanding of atoms by being able to see the atom itself, and lets us see some atomic reactions.
