- They are all nonreactive as they have a full outer shell.
- They all react with water and oxygen.
7. What do periodic table columns have in common?
- The elements have the same number of electrons in the outer shell, so have similar chemical properties.
- The number of electrons in the inner shell is the same, meaning that they have same chemical properties.
- The chemical properties are completely different but the number of electrons in the outer shell is exactly the same.
8. In an atom, what do the number of protons equal?
- The number of electrons.
- Nothing, they don't relate to anything.
- The number of neutrons.
9. Why do atoms bond?
- To have an outer shell full of electrons so the atom is stable.
- To create a new atom to react.
- So they can get rid of electrons.
10. What is the MASS NUMBER?
- The number of protons+neutrons.
- The number of electrons.
- The amount of atoms.
11. What charge does an atom have?
- Neutral.
- Positive.
- Negative.
12. Which best describes a compound?
- Part of an element.
- More than one atom bonded together.
- A few elements combined.
13. What is the atomic number?
- The number of protons.
- The number of atoms.
- The number of compounds in an atom.
14. Which best describes an element?
- One type of atom.
