Since the electron cloud is much larger than the nucleus, most of an atom is empty space. An atom is about 10 ⁻10 m in size, while the nucleus, at 10 ⁻15 m, is 100,000 times smaller.

Atoms are made up of even smaller subatomic particles, three types of which are important: the proton, neutron, and electron. The number of positively-charged protons and non-charged (“neutral”) neutrons, gives mass to the atom, and the number of protons determines the element. debt consolidation mortgage loan texas
