False. Electrons are not distributed randomly; they occupy specific energy levels or orbitals around the nucleus of an atom, which contains positively charged protons. The arrangement of electrons is governed by quantum mechanics, leading to a defined structure rather than a random distribution.
Random Pattern.
The plum pudding model ddi not employ the concept that the nucleus was the centre of the atom and that the electrons were not randomly placed around the nucleus but were in orbits in different energy levels. The Bohr model introduced the concept that a certain number of electrons could occupy each energy level and no more ie 2 8 8 18 18 32
Ernest Rutherford's model of the atom disproved the Plum Pudding Model proposed by J.J. Thomson. Rutherford's gold foil experiment led to the conclusion that the atom is mostly empty space with a small, dense nucleus at the center, which contradicted the idea of electrons being randomly distributed throughout the atom.
No, skin reflectance is not randomly distributed throughout the globe. It is influenced by factors such as evolutionary adaptation to the local environment, sunlight exposure, and genetic variations. As a result, there are noticeable patterns of skin reflectance that correspond to geographical regions and populations.

Atom
An atom contains neutrons and positively charged protons in its nucleus. Negatively charged electrons move randomly throughout the atom.

Random Pattern.
The Plum Pudding Model proposed by J.J. Thomson depicts electrons as dispersed throughout a positively charged atom, much like plums in a pudding. This model suggested that the atom is overall electrically neutral due to the balance of positive and negative charges. However, this model was later replaced by the Rutherford model which proposed a nucleus at the center of the atom surrounded by orbiting electrons.

J.J. Thompson was the person who suggested the plum pudding model for the atomic structure. He declared that the electrons are located between a cloud of the positive charges. This model was proven incorrect from the alpha particle experiment done by Ernest Rutherford.
