Most, 99.91%, of the lanthanum found in nature is 139La, which is not radioactive. The other 0.09% is made up of 138La, which is radioactive but has a very long half life of 105,000,000,000 years. Like all elements, lanthanum has synthetic radioactive isotopes.

What series are called elements 57 to 70?
Elements from atomic number 57 (Lanthanum) to 71 (Lutetium) are called the Lanthanides. Lanthanide means "like Lanthanum" and so, the Lanthanides are based on Lanthanum. Only one of the Lanthanides is radioactive: Promethium (Pm - No. 61)
How many protons neutrons and electrons are there in a neutral atom of the isotope of lanthanum named lanthanum-138?
Protons: Any atom of lanthanum has 57 protons. Neutrons: Lanthanum has 30 radioactive isotopes with neutron numbers ranging from 60 to 96 but the only stable isotope(139La) has 82 neutrons. Electrons: The number of electrons is normally the same as the number of protons.
Name an element that is stable by itself?
Examples (in the sense of non-radioactive): helium, oxygen, beryllium, caesium, lanthanum etc.
Is uranium a lanthanum series element?
The chemical element with atomic number 57 is Lanthanum (La). It is a Lanthanide, as it is what the rest of the Lanthanides are based on. It has 57 electrons in 6 shells. It is naturally occuring and non-radioactive.
What are the 2 words that describe the classification of the 17 chemical elements with the numbers 57-71?
Elements from atomic number 57 (Lanthanum) to 71 (Lutetium) are called the Lanthanides. Lanthanide means "like Lanthanum" and so, the Lanthanides are based on Lanthanum. Only one of the Lanthanides is radioactive: Promethium (Pm - No. 61)
