Explanation:

For each question, we arrange the given words into a grammatically - correct and scientifically - accurate sentence based on knowledge of the periodic table and chemical elements.

Answer:

1. Elements in the same group have the same number of outer electrons.
2. The atomic number is the number of protons in an atom.
3. Nonmetals are generally brittle and poor conductors.
4. As we move across the periods, the atomic number increases.
5. Alkali metals on the left are highly reactive.
6. Metalloids have properties of both metals and nonmetals.
7. Metals are good conductors of heat and electricity and shiny.
8. Nonmetals are found on the right side of the Periodic Table.
9. Metalloids appear in a staircase between the elements.
10. Most metals are in a solid state at room temperature.
