Who invented isotopes?
Frederick Soddy and Margaret Todd are credited with coining the term "isotope" in 1913 while working alongside Ernest Rutherford. Isotopes were discovered through their study of radioactivity.
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".
Could life exist without compounds?
Life as we know it relies on compounds such as proteins, nucleic acids, and lipids. These compounds are essential for the structure and function of living organisms. It is unlikely that life could exist without compounds in some form.
Is einsteinium flammable?
Einsteinium is a radioactive metal and not typically considered flammable. Its main hazard comes from its radioactivity rather than its flammability. However, due to its high radioactivity, special precautions should be taken when handling it.
What element has the atomic number of 168?
The element with the highest atomic number is Ununoctium (total quantity that has ever existed: three atoms), and its atomic number is 118. Thulium has an atomic weight of 168.9342.
Is it true that the atomic bomb couldn't exist without radioactivity?
Simply to put it Yes. Atomic Bombs is a form as Nuclear bomb and Nuclear products/elements such as Uranium 235 (a material used in a atomic bomb) emits radioactive particles. Radioactivity Particles = radioactivity.
Could a democracy exist without voting?
no
Could life exist on earth without water?
no
Did the US use an atomic bomb at all during ww1?
The atomic bomb did not exist until 1945, so no it could not be used by anybody in WW1.
Do hybridized orbitals exist in isolated atoms?
No, hybridized orbitals exist in molecules where atomic orbitals combine to form new hybrid orbitals. In isolated atoms, electrons occupy their respective atomic orbitals without hybridization occurring.
How do you calculate atomic mass of NaSO4?
NaSO4, if it could exist, would have a mass of 119.046 AMU. However, it cannot exist because the valencies do not agree.
Where does the element californium come from?
It is a man-made element and, due to its high radioactivity does not exist in nature.
Riddle castles and portholes could not exist without you?
The letter S.
Could life exist without global warming?
Yes. And also with it.
Could the US exist without compromise?
No. No one can exist without it. There will always be people who disagree with each other, so compromise is needed to get business done.
Why helium exist in mono atomic state?
Helium has completely filled orbitals, is stable and is not reactive. Hence they exist as mono atomic
What effects still exist in Japan from the atomic bombs?
no effects still exist. Nukes leave a lot of radiation etc but not atomic bombs
