Reading the Periodic Table
What does Atomic Mass tell us?
QUESTION… How could you find the number of neutrons??? Answer: Atomic # # of neutrons Atomic mass (rounded)
Lets give it a Try! How many protons, electrons, and neutrons does Ne have? 10 p + 10 e - 10 n 0
Let’s Practice… Find the number of p +, e -, and n for each element: 1. H 2. He 3. Tb 1 p + 2 p + 65 p + 1 e - 2 e - 65 e - 0 n 2 n 94 n
HOMEWORK… Find the number of p +, e -, and n for each element: 1. Si 2. Hg 3. Fe 4. Ta 5. Pt
