This has nothing to do with feminism or equality - it's just another example of the labour government cocking things upAll of our laws are a complete mess and most of them favour immigrants and persecutes victimsThe ethnic minority part of this has been happening for a whileJust because several warped wierdos are running Britain don't assume that their views are feminists or any one elses!!!!!!!!!!!!!!!!!!!!!!!!
The number of protons in the nucleus determines the behavior of an atomFor example, if you combine 13 protons with 14 neutrons to create a nucleus and then spin 13 electrons around that nucleus, what you have is an aluminum atomIf you group millions of aluminum atoms together you get a substance that is aluminum - you can form aluminum cans, aluminum foil and aluminum siding out of itAll aluminum that you find in nature is called aluminum-27The 27 is the atomic mass number - the sum of the number of neutrons and protons in the nucleusIf you take an atom of aluminum and put it in a bottle and come back in several million years, it will still be an atom of aluminumAluminum-27 is therefore called a stable atomUp to about 100 years ago, it was thought that all atoms were stable like thisrepresent a mixture of elements A and Bz the diagram should be with two a stuck together and two b stuck like the view of a binocularoo
