What are the actinides in the Periodic Table of Elements?
The actinide series is a group of elements in the periodic table that includes actinium, thorium, uranium, and all elements from atomic number 89 (actinium) to 103 (lawrencium). These elements are all radioactive and have similar chemical properties.
What was the significant change that Glenn Seaborg made to Mendeleevs periodic table?
Glenn T. Seaborg contibutedto the periodic table by discovering 8 different elements. He discovered americium (95), curium (96), berkilium (97), californium (98), einsteinnium (99), fermiuim (100), mendelevium (101), and nobelium (102). Element 106, seaborgium, bears his name.

There were 102 known elements on the periodic table in 1960.
How many solids are in the periodic table?
There are 118 elements in the periodic table, and most of them exist in solid form at room temperature and pressure. About 80% of the elements are classified as metals, with most of them being solids.
What is NO on the periodic table of elements?
NO is for element Nobelium.It is named in honor of Alfred Noble.Its atomic number is 102.
Why are the elements 57 through 70 and eighty through 102 found separate from the top of the periodic table?
These elements are termed as 'lanthanides' and 'actinides' have certain different characteristics that cannot be fitted into modern periodic table,hence they are placed at the bottom.
What is the name of the elements with atomic numbers 90 through 103?
The elements are called Actinides. They are placed at the bottom of periodic table. These elements have different properties.These elements are in the f group of the periodic table. Elements from Ac-Lr belong to this group. These are called Actinides.
Which elements are not in the periodic table song by Tom Lehrer?
There are 102 elements named in the song lyrics, in a totally disorderly order. The date of the song (1960-ish) gives a clue to which elements. For a long time around then there were just 102 recognised elements, all atomic numbers up to 102, and 103 and beyond were in process of discovery and recognition. So the elements that were not included were those artificial elements that had not yet been recognised: elements 103-114 and 116.
What does No stand for on the periodic table?
NO is a compound called nitrous oxide and is not on the periodic table. It is a combination of Nitrogen and Oxygen (N for nitrogen and O for oxygen) Periodic table lists only elements and not compounds.
Why are the elements 57-70 89-102 found seperately at the bottom of the periodic table?
They are lanthanides and actinides. They have different chemical properties , hence they are placed separately.

No stands for what on the periodic table'?
It is the symbol for the element, Nobilium (atomic number 102)
Who developed your modern day periodic table?
The last major changes to the periodic table resulted from Glenn Seaborg's work in the middle of the 20th Century. Starting with his discovery of plutonium in 1940, he discovered all the transuranic elements from 94 to 102. He reconfigured the periodic table by placing the actinide series below the lanthanide series. In 1951, Seaborg was awarded theNobel Prize in chemistry for his work. Element 106 has been named seaborgium (Sg) in his honor.Although Dmitri Mendeleev is often considered the "father" of the periodic table, the work of many scientists contributed to its present form.
What are the actinides in the Periodic Table of Elements?
The actinide series is a group of elements in the periodic table that includes actinium, thorium, uranium, and all elements from atomic number 89 (actinium) to 103 (lawrencium). These elements are all radioactive and have similar chemical properties.
