- The following graphics represent the nuclei of atoms. Using a periodic table of elements, fill in the table.
- Look at a periodic table. The atomic mass of hydrogen is 1.00794. Why is this number not rounded off to 1?
- How many protons and neutrons are in the nucleus of each isotope? a. hydrogen-2 (atomic number = 1) b. scandium-45 (atomic number = 21) c. aluminum-27 (atomic number = 13) d. uranium-235 (atomic number = 92) e. carbon-12 (atomic number = 6)
- Although electrons have mass, they are not considered in determining the mass number or atomic mass of an atom. Why?
- A hydrogen atom has one proton, two neutrons, and no electrons. Is this atom neutrally charged? Explain your answer.
- An atom of sodium-23 (atomic number = 11) has a positive charge of +1. Given this information, how many electrons does it have? How many protons and neutrons does this atom have? What the nucleus looks like What is this element? How many electrons does the neutral atom have? What is the mass number?

Periodic Table Review Answer Key
Directions: Complete the chart using a periodic table. M- metals NM- Nonmetals MT- metalloids Element lithium neon Fluorine M, NM, MT M NM NM Reactivity Highly Reactive Non-Reactive Highly Reactive Directions: fill in the blanks to the statements below. Vertical columns on the periodic table are called groups. Horizontal rows on the periodic table are called periods. The number of protons in an atom is that element’s atomic number. The total of the protons and neutrons is that atom’s mass number. The elements in group 1 are the most reactive metals. The elements in group 17 are the most reactive nonmetals. The elements in group 18 are very unreactive.
