That is one question that defies a definitive answer. Some theorists believe it has always existed (and that sidesteps the question) and others theorize that it may have been created by a race of super inter-dimensional beings and deposited here by way of a wormhole (who knows?!) But all in all, mathematics bears out the fact that it did, indeed, exist owing to the fact that universal expansion, if regressed, would wind down to a singular point (the ''singularity''). Beyond that, nothing is verifiable. But, till mankind has developed higher intellegence and accumulated enough knowledge to answer this question directly, perhaps it would serve to read the book of Genesis and interpret each of the Creator's 'Day' in terms of Billions of years.
HASSAN SAJJAD A GREAT MUSLIM SCIENTIST was able to see atom for first time ever although he didnt knew about it he named it as *rasheed*
An ATOM!!!! An atom can be sub-divided in to protons, neutrons, and electrons.
A neutral atom is an atom with an equal number of electrons and protons without any additional energy. An excited atom has electrons that have absorbed energy and moved up to another layer. Ions are atoms that have a different number of electrons from the neutral atom.
In 1963, with the first episode being An Unearthly Child.
Ernest Rutherford made his discoveries through his pioneering work in the field of nuclear physics. He conducted the famous gold foil experiment where he observed the scattering of alpha particles, leading him to propose the nuclear model of the atom. His experiments and observations paved the way for future breakthroughs in understanding the structure of the atom.
First Germany second United States of America
Dalton didn't discover the atom. Democritus did. Dalton, however was the first to use the word atom. which comes from the GGreek word atomos, meaning "cannot be split"
Rutherford presented the nuclear model of atom first.
split the atom
This month
who was the u.s afraid would get an a atom bomb first
No one has ever seen an atom
No. Ancient Greek philosophers postulated the existence of atoms.In 1803, John Dalton proposed an atom to explain chemical reactions that had been observed by scientists since the 1800's.
the usa was the first to develop the atom bomb thanks to albert Einstein
strong force
It is stored in the atom.
The first shell of an atom can hold a maximum of 2 electrons. Since the number of protons in an atom is equal to the number of electrons in a neutral atom, there can be a maximum of 2 protons in the first shell.
