How are elements artificially produced?

Question

I know basic chemistry, but help me out with this one. On the Periodic Table of Elements, there are several elements which are artificially produced. An element is the most basic, simple thing. So how can one create a new one working only with existing elements? Also, why are some listed on the Table, though they are noted as "Not Yet Produced". How can they even be on the Table if they don't exist?

Answer 1

All elements with atomic number higher than 92 (Uranium) are artificially produced. To do so, they accelerate a neutron (which is hard since neutron has no charge) and then bombard a lighter nucleus with them. The nucleus absorbs a neutron, releases an electron (beta ray) and keeps a proton, so the atomic number will raise one number. (n -> e + p)
They do it again and again until they reach the element that they want. but the higher the atomic number, the lower the half life will be (they will last from few months to few micro seconds) when they say that an element is not yet produced but they put it in the periodic table, this means they have evidence that is should exist, but since the half life is short they are unable to detect it, so they have to wait for technology to advance so they can detect it.

Answer 2

the elements are artificially produced in labs by splitting from radioactive compounds by hitting them with neutrons, protons... these elements are sometimes radioactive and have a very short half life time but sometime these are very stable...

the ones that are stable enough to be studied are placed in the table according to their properties.

then there are the ones which should be present but have not been made as yet by any of the processes.. but should be there because the elements before or after them have been syntesised.

i hope i have been able to help you,

Answer 3

take an atom of americium - ram it together really really hard with say an aton of helium -and if the atom smasher is fast enough, you get Berklium.

Fusion in a nutshell. with the proper elements, and energies, you overcome the nuclear forces and they stay together for a short time, until they decay (and they all do, some only last milliseconds).

As you know the periodic table is set up in rows and columns that reflect electron shells, so you can predict where molecules will be - then you try to make it - yoyu just need the corect elements, and energies

Answer 4

often, factors with atomic numbers below ninety 3 are chanced on, clearly. There are in elementary terms 2 exceptions: #40 3, Tc and #sixty one, Pm. factors ninety 3 on up are synthetically made. they could have been in the international at one time yet are radioactive and could have decayed into yet another element via now. That makes 28 by element 118.
