Which of the following statements best describes the elements in Group 8A (18) of the periodic table? a. They are all liquids under normal conditions. b. They exist naturally as single atoms. c. They form ions of variable charge. d. They exist as diatomic molecules.
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.
