Barium is a member of the alkaline-earth metals. 2019-06-02 · Atoms are made of protons, neutrons, and electrons. Protons carry a positive electrical change, while electrons are negatively charged, and neutrons are neutral. A neutral atom has the same number of protons and electrons (charges cancel each other out).

Name: Barium Symbol: Ba Atomic Number: 56 Atomic Mass: 137.327 amu Melting Point: 725.0 °C (998.15 K, 1337.0 °F) Boiling Point: 1140.0 °C (1413.15 K, 2084.0 °F) Number of Protons/Electrons: 56 Number of Neutrons: 81 Classification: Alkaline Earth Crystal Structure: Cubic Density @ 293 K: 3.51 g/cm 3 Color: Silver Atomic Structure
Naturally occurring barium (56 Ba) is a mix of six stable isotopes and one very long-lived radioactive primordial isotope, barium-130, identified as being unstable by geochemical means (from analysis of the presence of its daughter xenon-130 in rocks) in 2001.
