Map Elements that appear in the same column of the periodic table often share similar chemical properties. In the case of the alkaline earth metals, this is troublesome since the body+ treats calcium (necessary for proper bone growth) and radium (a radioatictive element) as chemically similar, storing both in bone marrow. The radium then bombards nearby bone cells with alpha particles, causing them to onized -isotope crumble." Radium poisoning investigations often center on the identification of radium and its isotopes...

A Review Constants 1 Periodic Table Subm Previous Answers Correct When identifying isotopes of an atom, we look for atoms that have the same number of protons but different masses. This means that each isotope has a different number of neutrons. In an atomic symbol of an isotope, the upper left number represents the mass number (which consists of the sum of protons and neutrons in the nucleus of the atom) and the lower left number is...

Question 5 (2 points) What does the periodic law state? When elements are arranged in order of increasing atomic number, there is a recurring pattern to their physical and chemical properties. When elements are alphabetized, there is a periodic pattern to their physical and chemical properties within a period. When elements are arranged in order of increasing atomic mass, there is a recurring pattern to their physical and chemical properties. When elements are arranged in order of increasing atomic size,...
