WATCH THIS VIDEO BEFORE STARTING THIS WIZER.ME! YOU CAN USE IT TO HELP YOU WITH ANSWERING QUESTIONS ALSO. Fill in the blanks by clicking on the blank, then choosing the correct term. All the atoms of elements are exactly the same. The number at the top of an element's symbol on the periodic table is called the atomic number. The atomic mass is the number of protons plus neutrons. Protons are found in the nucleusof an atom, while electrons are found in energy levels. Neutronsand protons make up the nucleus of the atom. Where is most of an atom's atomic mass? In the nucleus In the energy levels Atoms do not have atomic mass It cannot be determined How can you determine an atom's atomic mass? Add the protons and electrons together Add the protons and neutrons together Add the electrons and neutrons together It cannot be determined Match the subatomic particles with their charge and mass. protons positive, 1 amu neutrons neutral, 1 amu electrons negative, 0 amu Fill in the missing spaces below. ROUND THE ATOMIC MASS! 9 19 9 10 9 Fill in the missing spaces. ROUND THE ATOMIC MASS! 3 7 3 4 3 Use the periodic table below to answer the questions that follow. Elements that have some characteristics of metals and some characteristic of non-metalsare called: Elements Metalloids Noble Gases Transition Metals Elements with chemical properties (characteristics) similar to Neon (Ne) are found only in group 18 (noble gases) group 1 period 1 period 2 Which element is classified as a noble gas? Sulfur (S) Argon (Ar) Oxygen (O) Nitrogen (N)
