Which statement accurately describes the charge of the nucleus of an atom? A. The nucleus can be either positively charged or ne
utral. B. The nucleus never has an electrical charge. C. The nucleus always has a positive charge. D. The charge of a nucleus can change from positive to negative.
An atom contains three sub-atomic particles namely protons, neutrons and electrons.
The nucleus of an atom contains protons and neutrons only. Whereas electrons revolve around the nucleus. Protons are positively charged, neutrons have no charge and electrons are negatively charged.
When an atom is neutral then number of protons equal the number of electrons. Hence, the atom becomes neutral as positive charge is equal to negative charge and thus gets cancelled.
Therefore, a nucleus can be either positively charged or neutral.
Due to the known fact that certain animal ect lived on certain country/continents due to climate water type ect when fossils of various animal where found in unusual parts of the earth the theory came that all the continent where joined together due to fossil and rock types being found on continents in which would be impossible to reach if not joined together in the beginning
