Consider the following statements (I, II, and III). The number of neutrons in an atom is always equal to the number of protons in the atom. The number of electrons in an atom is always equal to the number of protons in the atom. An atom is electrically negative because it has electrons. Select all the correct statements. The mass of a certain substance is 17.5 kg. The density of the substance is 1.71 g/mL. Determine the volume (in liters) of the substance. An empty container weighs 19.278 g. When the container is filled with water, it weighs 29.107 g including the weight of the container. When the same container is filled with an unknown liquid instead of water, it weighs 32.075 g including the weight of the container. What is the density (in g/mL) of the unknown liquid? Assume that the density of water is 0.997 g/mL. Round your answer to three significant figures. Group of answer choices

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.
