Atoms of the first ten elements

Référence de la vidéo 11928920
Pan across the first ten atoms of the Period Table of elements, with their chemical symbols and atomic number. These are, from left to right: hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine and neon. Atoms are differentiated by the number of protons (red) in their central nuclei, from one (hydrogen) to ten (neon). The nucleus also contains a neutral neutron. Each proton has a single positive charge, meaning that the atom contains an equal number of negatively charged electrons. Electrons (small balls) occupy orbitals around the nucleus, each of which can hold two electrons. The first orbital is called 1s (inner green sphere), the second 2s (outer green sphere), then there are three bi-lobed 2p orbitals (blue, yellow and red) arranged perpendicularly to each other. It is the arrangement of an atom's electrons that is the major determinant of an element's chemical behaviour.
