A fictitious element name Brickminium can be found as three isotopes. Their relative abundances are given in the table. Based on this, what is the relative atomic mass of Brickminium? Isotope Abundance Brickminium-95 3.4 % Brickminium-96 65.0% Brickminium-98 31.6%

Periodic table The periodic table lists two main numbers for each element. The atomic number is an integer that equals the number of protons. The number of neutrons is not given in the periodic table because it will vary with different isotopes. The mass number of an element is the sum of the protons and neutrons. To find the number of neutrons, the atomic number must be subtracted from the mass number. Elemental symbol When writing the symbol for an element, a superscript indicates the mass number and a subscript indicates the atomic number. For example, Chas a mass number of 14 and an atomic number of 6. This isotope can also be written as just ¹4C. You do not need to put in the 6 because the atomic number of carbon is always 6 regardless of which isotope you are dealing with. Part B . .
