Atomic numbers, Mass numbers Atoms & PT_Diagramming Atoms Day 1 There are 3 types of subatomic particles. We already know about electrons (e–) & protons (p+). Neutrons (n0) were also shown to exist (1930s). They have: no charge, a mass similar to protons Elements are often symboliz...
While isotopes with atomic numbers higher than lead (82) are known to be radioactive, an "island of stability" has been proposed for some elements with atomic numbers above 103. Embora se saiba que os isótopos com número atómico maior do que o chumbo (82) são radioativos, tem sid...
