What is the electron configuration of lawrencium?
[Rn] 5f14 7s2 7p1
How many protons does cesium have?
What is the atomic mass unit of lawrencium?
What is the 103rd element?
Element 103 in the periodic table is called lawrencium. It was first synthesised in 1961 at what was then called the Lawrence Radiation Laboratory, situated close to San Francisco.
What has an atomic number of 100?
Fermium (Fm), synthetic chemical element of the actinoid series of the periodic table, atomic number 100.
Which atom has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d2?
So, an antimony atom with charge +2 has an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p1.
Is cesium alpha beta or gamma?
A legacy of atmospheric nuclear bomb tests and accidents Caesium 137 is a radioactive element with a relatively long half-life of 30.15 years. This particular isotope of caesium is both a beta and gamma emitter. It is produced in some abundance by fission reactions.
What do you call the element from atomic number 57 71?
The elements from atomic number 57 to 71 are called Lanthanides. They are called lanthanides, since lanthanum is chemically identical to the elements in the sequence. The lanthanides are between Barium and Hafnium.
Does the human body use lawrencium?
Lawrencium has no uses outside research. Lawrencium has no known biological role. Lawrencium does not occur naturally. It is produced by bombarding californium with boron.
