What are Elements?

Elements are particular kinds of atoms that all have the same atomic number or proton number. This is the number of protons in the nucleus. Atoms also have the same number of electrons orbiting the nucleus in shells as the number of protons. Elements have different properties which are determined by the number of protons and electrons they have. Carbon for example which is one of the most important elements for life has 6 protons and 6 electrons. Carbon is a unique element as it can form many different types of molecules, each bonded together in varying ways.

Which Elements are the Most Important?

As we just mentioned, carbon is one of the most important elements for life but there are several others that are essential for the processes which keep us alive and well. Oxygen is another crucial element that is involved in the process of aerobic respiration. This is the mechanism by which we turn glucose into energy to fuel our cells for growth and repair. Other elements like lithium are important for manufacturing batteries that are used in all of our devices.

Where do Elements Come From?

Elements are formed in the centre of stars like our sun during the process of nuclear fusion. During nuclear fusion, hydrogen nuclei are forced together due to their high temperature and thus speed of movement. Usually, the force of repulsion keeps them from merging since they are positively charged. This powerful force is overcome due to high velocity and the strong nuclear force takes over and pulls the two nuclei together. The hydrogen nuclei then merge into a helium nucleus and energy is released. The same process repeats with heavier elements all the way down to iron.
