Atom Structure and Components
- The nucleus is the central part of the atom, housing protons and neutrons.
- Electrons are negatively charged particles located in the electron cloud, crucial in chemical bonding and reactions. Their existence was established by JJ Thomson.
- Neutrons are neutral particles found within the nucleus, contributing to atomic mass without affecting electrical charge. They were discovered by James Chadwick.
- The electron cloud refers to the area surrounding the nucleus where electrons are situated, representing the probable locations of these particles.
- Protons are positively charged particles also located in the nucleus, fundamental to determining the atomic number and identity of an element, first identified by Ernest Rutherford.
- Atoms consist of predominantly empty space, highlighting that most of their volume is not filled with matter but rather consists of the electron cloud surrounding the nucleus.
