Which of John Dalton’s theories given below were found to be INCORRECT? 1. the atoms of elements remain unchanged when they combine to form chemical compounds 2. the atom is the smallest unit of matter that retains its chemical identity 3. all atoms of the same element are identical 4. the atom cannot be divided into any smaller unit of mass
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.
