Was the modern periodic table organized according to atomic mass?
Initially, the modern periodic table was organized based on atomic mass. However, it was later revised to be arranged according to atomic number, which is the number of protons in an atom's nucleus. This change led to a more accurate and logical representation of the periodic trends.
Which element has lowest atomic number and is not found in nature?
Hydrogen has the lowest atomic number, and is not found in nature as individual atoms, but is found in nature as the diatomic molecule, H2.
How the atomic mass of an element is affected by the distribution of its isotopes in nature?
The atomic mass of an element is the average of its isotopes, weighted by abundance in nature.
How do the elements change as you go to the right along a row of the periodic table?
the elements change from right to left because group 1 has 1 electron in their highest energy level and group 2 has 2 electrons in the highest energy level and so on. The transition metals are a totaly different thing so dont worry about those.
Why chlorine has atomic weight 35.5 though no chlorine with mass exist in nature?
The atomic weight (not mass) of chlorine is now [35,446; 35,457]. I don't understand "no chlorine with mass exist in nature".

How did World War 2 change the nature of warfare?
There was introduction of the atomic bomb, and mass production of tanks.

What is average atomic number?
There is no average atomic number. The atomic number of an element is the number of protons in the nuclei of its atoms. It is a whole and finite number. The elements are arranged in order of increasing atomic number on the periodic table.

Who developed the idea of the atomic matter of nature?
Democritus
Can an animal change its nature to human nature?
i think that we were not at all any monkeys so animals can not change there nature to human nature

Caprice of nature?
the caprice of nature is the sudden change of the nature
What is the atomic mass of gadolinium?
The atomic mass of gadolinium is 157.25 (which is the measured mass based on the various isotopes which occur in nature).
