decay or the rate of other cumulative changes in atoms resulting from radioactivity. The various isotopes of the same element differ in terms of atomic mass but have the same atomic number..One half-life is the amount of time required for of the original atoms in a sample to decay.If you only have a single coin than the event is very random and you might get several heads or tails in a row.If you have 1000 coins that you toss most likely you would get about 500 coins coming up heads.Other atoms are also named based on the number of protons they carry.Notice in the diagram that eight different isotopes of Carbon are illustrated.But once they interact with the atmosphere, They produce showers of subatomic particles of many different types, including — for our purposes — the all important neutron.The reason neutrons are so important is because our atmosphere is 78% nitrogen, which you may remember as the thing that carbon-14 decays .

Most carbon atoms have six positively charged protons and six uncharged neutrons.

An atom that is radioactive is similar to the dice, each atom has a certain probability that it will decay each second, when you have large enough number of atoms the random event becomes much more uniform.

If you toss your bag of 1000 coins you would expect half of them to be heads if we removed all the coins that are heads you would be left with about 500 coins.

Most nitrogen atoms have seven protons and seven neutrons, so their atomic mass is 7 7 = 14.

The fact that it has seven protons is what makes it nitrogen.
