WebMar 9, 2024 · How many atoms are in C2? Now, the equation also tells us that 2 atoms of C will produce one atom of C2 which is the same as saying that 2 moles of C atoms will produce one mole of C2 molecules. Therefore the number of C2 atoms which will be produced is (2 * 6.022*10^23) /2 = 6.022*10^23 atoms, or one mole of C2. WebElements, such as helium, depicted here, are made up of atoms. Atoms are made up of protons and neutrons located within the nucleus, with electrons in orbitals surrounding the nucleus. All atoms contain protons, electrons, and neutrons (Figure 2). The only exception is hydrogen (H), which is made of one proton and one electron.
