Matches the chemical name of each oxide of phosphorus to its chemical formula

Use the periodic table to determine the electron configuration of dysprosium (dy) and americium (am) in noble-gas notation.

Given the following information: mass of proton = 1.00728 amu mass of neutron = 1.00866 amu mass of electron = 5.486 × 10^-4 amu speed of light = 2.9979 × 10^8 m/s calculate the nuclear binding energy (absolute value) of 3li^6. which has an atomic mass of 6.015126 amu. j/mol.
