Atoms with the same number of protons but a different number of neutrons. 5 of 8 What is mass spectrometry? A method to measure the atomic/molecular masses in a sample. This can be used to find the abundancie in the sample. 6 of 8 What is nuclear fusion? When 2 light atomic nuclei fuse to create a single, heavier nucleus. 7 of 8 Why is it difficult to do neuclear fusion on earth? Extreamly high pressures and temperatures are needed. The perfect conditions can be found in the sun. 8 of 8
