Promethium is the element that is naturally found on Earth but is labeled as a laboratory-made element on the Periodic Table. Although traces of promethium have been found in uranium ores, it is primarily produced artificially through nuclear reactions.

Latest element in the periodic table?
As of now, the latest element in the periodic table is Tennessine with the atomic number 117. It was officially added to the periodic table in 2016.
What is the term of Group in the periodic table?
A group is a vertical column on the periodic table. In the past, they were labeled 1A, 2A all the way up to 8A for the noble gases with the transition elements being labeled using 1B, 2B, etc. in the United States. Recently, the IUPAC has numbered the groups as 1-18. For the representative elements, the ones column of the group number delineates the number of valence electrons in the atoms of each element.
What is laboratory technique in which the body radioactively labeled a substance is mixed with a blood specimen?
The laboratory technique you are referring to is known as radioimmunoassay (RIA). In RIA, a radioactive substance is used to label a specific molecule or antigen, and when this labeled molecule is mixed with a blood specimen containing the corresponding antibody, the level of radioactivity can be used to quantify the amount of antigen present in the blood sample.
What is a family how many are there in periodic table?
In chemistry, a family is a group of elements that have similar properties and react in a similar way. There are 18 families in the periodic table, each with their own unique characteristics and trends. These families are commonly referred to as groups and are labeled from 1 to 18 on the periodic table.
Is there any element which has 86 protons and 136 neutrons?
The chemical element, Radon, has an atomic number of 86, meaning it has 86 protons. Were there an isotope of Radon that had 136 neutrons, it would be labeled as 222Rn. Well, it turns out that this isotope does exist and has a half-life of 3.82 days.

What is Zu on the periodic table?
There is no element labeled "Zu" on the periodic table. If you're looking for an element symbol, it may not exist in the current periodic table. If you provide more context or details, I may be able to help you further.
How many protons dose a atom have?
The number of protons in an atom is different for every element. If you look at the periodic table, then the number labeled "atomic number" is the number of protons.
The element labeled X is the most abundant element in the body. what is element X?
the element labeled X is the most abundant element in the body. what is element X
Why do electronegaativity decrease as you move down a group?
Most often yes, if you're unsure, look on the periodic table, the elements electronegativity is usually located labeled, i.e electronegativity of F (the most electronegative element) is 4.0

Where is steam terminal 7?
I believe it is by the large door labeled,"Living Quarters" - you will need a key from the laboratory on the other side of the island
Horizontal row in the periodic table?
A horizontal row in the periodic table is called a period. There are seven periods in the periodic table, labeled from 1 to 7. Each period represents the energy levels of the elements within that row.
Where is the atomic number written?
The Atomic Number Is Located On The TOP Of The Element Symbol. So Example. 14<ATOMIC NUMBER> Si<Symbol> 28.086<Atomic Mass> Silicon <The Name> This Is The Correct Order Of An Element That Should Be Labeled.
What must be done to ensure DNA in a laboratory is radioactive?
Incorporating radioactive nucleotides must be done to ensure that DNA made in a laboratory is radioactive.
