A fictional element Ho has two stable isotopes and an average atomic mass of 18.357 amu. Use the information in the table to calculate the mass of a 20Ho atom, Isotope Isotope Mass Relative Abundance 18Ho 17.990 amu 78.920%, 20Ho ? ? Group of answer choices 18.455 amu 23.260 amu 19.990 amu 19.731 amu
Atomic Structure
The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.
Shape of the D Orbital
Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.
