Question 4 An element with an average atomic mass of 87.62 naturally exists as 4 stable isotopes with masses of 84, 86, 87, and 88. Which statement is correct The isotope with mass of 87 is the most abundant. The isotope with mass of 86 is the most abundant. All isotopes are equally abundant. The isotope with mass of 88 is the most abundant.
Elements have isotopes with different mass numbers for same element.The average isotopic masses gives atomic mass of the element as a whole.hencethe term average atomic mass.
The difference between atomic mass and average atomic mass is that atomic mass has to do with the periodic table. and it's the number that is in each block, you subtract the number of protons from.

Practice Problems 1. Chlorine has two isotopes. Chlorine-35 has an actual mass of 34.9689 u and chlorine-37 has a mass of 36.9659 u. In any sample of chlorine atoms, 75.771% will be chlorine-35 and 24.229% will be chlorine 37. Calculate the average atomic mass of chlorine. 2. Copper has two isotopes. Copper-63, which has an atomic mass of 62.93 u and copper-65, which has an atomic mass of 64.
Atomic Mass. Because each proton and each neutron contribute approximately one amu to the mass of an atom, and each electron contributes far less, the atomic mass of a single atom is approximately equal to its mass number (a whole number). However, the average masses of atoms of most elements are not whole numbers because most elements exist naturally as mixtures of two or more isotopes.
