the last one.
The fifty first element in the periodic table of elements is antimony, with the symbol Sb and atomic number 51.

The heaviest natural radioactive element is Uranium.Man made elements are continuously being made. The latest heaviest superheavyweight man made element to be discovered is element 117 (it is still so new that it hasn't been given a name yet).A little different bit of information about Fermium, a team has captured a piece of its spectrum-the wavelengths of light it absorbs-making it the heaviest element ever to be so measured. It was made in the 1952 detonation of the first thermonuclear bomb. It does not make it as the heaviest element, just the heaviest to have it's light spectrum captured.
The heaviest man-made element is Oganesson (Og), with an atomic number of 118. It is a synthetic element that was first synthesized in 2002 by Russian and American scientists. Oganesson is highly unstable and has a very short half-life, making it difficult to study.
This element is ununoctium (Uuo): atomic number 118.
yes
The spelling of the ordinal number 51st is "fifty-first."
The heaviest sediment will always be deposited first. Which sediment is the heaviest in that flowage can vary widely.
The ordinal number 50th is spelled fiftieth.
The atomic number of an Element refers to it's position in The Periodic Table. The first element (Hydrogen - H) has the atomic number 1. The second element (Helium - He) has the atomic number 2. The fifty-second element (Tellurium - Te) has the atomic number 52. And so on.
The worlds heaviest lemon weighed a whoppin 11 lbs. 9.7 oz. Search google: what is the world's heaviest lemon and click on the first link. It's pretty cool! :) :)
