Step 1: Identify the element symbol 'Hg' and locate it on the periodic table. Determine its name, atomic number, and classification as a metal, metalloid, or nonmetal.
Step 2: Identify the element symbol 'At' and locate it on the periodic table. Determine its name, atomic number, and classification as a metal, metalloid, or nonmetal.
Step 3: Identify the element symbol 'Mo' and locate it on the periodic table. Determine its name, atomic number, and classification as a metal, metalloid, or nonmetal.
Step 4: Identify the element symbol 'W' and locate it on the periodic table. Determine its name, atomic number, and classification as a metal, metalloid, or nonmetal.
Step 5: Identify the element symbol 'Sn' and locate it on the periodic table. Determine its name, atomic number, and classification as a metal, metalloid, or nonmetal.

Textbook Question

Massspectrometry is more often applied to molecules than to atoms. We will see in Chapter 3 that the molecular weight of a molecule is the sum of the atomic weights of the atoms in the molecule. The mass spectrum of H2 is taken under conditions that prevent decomposition into H atoms. The two naturally occurring isotopes of hydrogen are 1H (atomic mass = 1.00783 amu; abundance 99.9885%) and 2H (atomic mass = 2.01410; abundance 0.0115%). (a) How many peaks will the mass spectrum have?
