Is berkelium a man made element?
Yes, berkelium is a man-made element that was first synthesized in a laboratory. It is a radioactive element with the atomic number 97 and is not found naturally on Earth.
What is the name of the element with the lowest atomic number?
The element with the lowest atomic number is hydrogen.
What does the chemical symbol rg mean?
Rg stands for the element, Roentgenium, atomic number 111.
What is am element?
Element Am is Americium. Americium is radioactive element number ninety five. I would not wanna mess with Americium
How man protons does an element have to have to make it radioactive?
An element can be radioactive regardless of its number of protons. Radioactivity depends on the specific isotopes of an element, which can have different numbers of neutrons. Elements with unstable isotopes that undergo radioactive decay typically have too few or too many neutrons compared to the number of protons.
First element known to be radioactive?
Uranium is the first element known to be radioactive. It was discovered by Henri Becquerel in 1896.
Heaviest element that is highly radioactive?
The heaviest element that is highly radioactive is Ununoctium, which has an atomic number of 118.
Which element is Atomic number- 112?
The element with an atomic number of 112 is called Copernicium. It is a synthetic, radioactive element that can only occur in a laboratory.
What element was named after the state of California?
This element is californium (Cf): first made in 1950, artificial radioactive element, atomic number 98, metal actinoids group.
What is the radioactive element in period 5?
The radioactive element in period 5 of the periodic table is Actinium (Ac). It is a radioactive metal with atomic number 89.
Can the atomic number change over time?
No. The atomic number of an element never changes. It is the number of protons and it defines the element. In certain types of radioactive decay, the number of protons can change, but then it is no longer the same (parent) element, but rather is a new (daughter) element.
What is first radioactive element of periodic table?
Bismuth
Is berkelium a man made element?
Yes, berkelium is a man-made element that was first synthesized in a laboratory. It is a radioactive element with the atomic number 97 and is not found naturally on Earth.
How many protons are needed for a element to be naturally radioactive?
Whether an ISOTOPE (not element) is naturally radioactive depends not only on the number of protons, but also on the number of neutrons. For EVERY element, there are radioactive isotopes.There has to be a certain relationship between the number of protons and the number of neutrons, but the relationship isn't a simple one.
Element number 105?
The element with atomic number 105 is Dubnium (Db). It is a synthetic element that was first synthesized in 1968 by a team of Russian scientists. Dubnium is highly radioactive and has no known biological role.
Is the element sodium radioactive or non-radioactive?
non radioactive element
Is uranium the first radioactive element?
Radioactivity is discovered on uranium.
