Atomic Mass
isotops
Oxygen has 3 stable isotops found in the nature 16O (99,757%), 17O (0,038%), 18O (0,205%). There are also 14 other isotops made by humans, but the most stable one is 15O with a half-life of 122 seconds.
Atoms of same element with same atomic number,which have different mass number is called isotops.
No, that is why we have isotops. Example: hydrogen can have 0,1,2 neutrons
Yes, radioactive isotops used for some medical scans come from nucular power.
Radio active isotopes are unstable isotopes of an element as there neutron number degenerate by emission of light or medium.
iron has 26 protons
cast iron, stainless steel, wrout iron, pig iron
1 mg of iron is equal to 0.001 grams of iron.
There are many iron compounds. Some of the most common of these are iron oxide, iron acetate, iron phosphate and iron sulfate.
