A: This is a great philosophical question and the answer all depends on how you define "alive." We don't usually say somethingis alive unless it can at least grow or reproduce or metabolize. While atoms can join together to form beings that do these things, individual atoms do not. How...
hi, how do we calculated the number of atoms at the start of universe i.e, after big bang? Technically, atoms couldn't form and remain stable until the recombination epoch, about 380,000 years after the Big Bang. Some of the best evidence for the Big Bang theory itself, comes from ...
Atoms are the basis of all the elements in the universe, the building blocks of all visible matter, and the secret to nuclear power.
How To Know If Atoms Exist? If we cannot see atoms, then how’d we know it actually exists? Science is known to offer pieces of evidence for each of its concepts. Hence, the evidence to prove atoms really exist is offered in a variety of forms. Scientists have actively split big ato...
How do we know that matter is composed of atoms? Explain why the the structure of a molecule/compound is important. Briefly explain the early theories of atomic structure. How does an atom produce color? Describe atomic theory and discuss how it explains...
Why do electrons just drift, and how do we know that if we can'tsee them? Why does their speed have to be constant? What wouldhappen if it slowed down or sped up? How does incident light that falls on an object affect the motion of electrons in the atoms of the object?
Atomic number:The number of protons in an atom's nucleus is referred to as the atomic number of that element. The number of protons defines what element it is and determines its chemical behavior. For example,carbon atomsalways have six protons;hydrogen atomsalways have one; andoxygen atomsalw...
