What characteristic was used to organize the first periodic table?
Mendeleev arranged the periodic table according to increasing atomic mass. This method has been used since he first developed it in the 1800s.
How were the elements in the periodic table arranged?
By Atomic Mass
How was the periodic table first organized atomic number or atomic mass?
The periodic table was first organized by atomic mass. However, after the discovery of isotopes and inconsistencies around this method, it was later rearranged based on atomic number, which reflects the number of protons in an atom's nucleus.
How is the order different to the first attempt in the periodic table?
The order in the first attempt in the periodic table was in the increasing order of atomic weights of atoms. This gave 2 different places for isotopes of the same element with same properties and the same place for isobars with different properties. This was so because chemical properties of an element depends on its number of electrons which is basically given by the atomic number and not atomic weight. Again the lanthanides and actinides had different places inspite of having similar properties due to same atomic number.
Who developed the first model of an atom with electrons on the outside?
Ernest Rutherford developed the first nucleus and electron model of the atom. It was based on experiments conducted by Geiger and Marsden.
Which country developed the atomic bomb?
We developed the first working atomic bomb but, GER. made up the idea.
Who developed the first scientific atomic theory?
john dalton developed the atomic theory , which he published in 1803
How was the periodic table first arranged?
The periodic table was first arranged by Dmitri Mendeleev in 1869. He organized the elements by increasing atomic mass and grouped them based on similar chemical properties. Gaps were left for undiscovered elements, with their properties predicted based on neighboring elements.
What characteristic was used to organize the first periodic table?
Mendeleev arranged the periodic table according to increasing atomic mass. This method has been used since he first developed it in the 1800s.
What New Mexico town is known for being the site where scientists developed the first atomic bomb?
The atomic bomb was developed at Los Alamos.

Who wrote the first atomic therory?
John Dalton (1766-1844) developed the first atomic theory around 1803
Where in Tennessee was the first atomic bomb developed?
It was in New Mexico, not Tennessee
What did the scientist who developed the atomic bomb believe?
That there was a great danger if Germany did it first.
What happened prior the First Atomic Blast in 1945?
Scientists developed the atom bomb.
When was calculus first developed?
Based on the history, calculus was first developed by Sir Issac Newton in 1665-1667.
When did Hantaro Nagaoka first start working on the atomic theory?
He started working on the atomic theory in 1892. He developed the Saturnian Model in 1904.
