Mass numbers of typical isotopes of Carbon are 12 13. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. The atomic mass is carried by the atomic nucleus, which occupies only about 10 -12 of the total volume of the atom or less, but it contains all the positive charge and at least 99.95% of the total mass of the atom. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. The atomic radius of Carbon atom is 69pm (covalent radius). It must be noted, atoms lack a well-defined outer boundary. The glassware elements of ChemDoodle are the most customizable (optionally filled or not, alteration of colours, flipping, addition of tubing, etc.): A very useful feature in ChemBioDraw and ChemDoodle is the TLC plate tool, especially for the users of laboratory e-notebooks. The atomic radius of a chemical element is a measure of the distance out to which the electron cloud extends from the nucleus. Any of the hydrogen atoms can be replaced with another carbon atom covalently bonded to the first carbon atom.

However, this assumes the atom to exhibit a spherical shape, which is only obeyed for atoms in vacuum or free space. Carbon with another element chemdoodle free#
In this way, long and branching chains of carbon compounds can be made (Figure 2a). The carbon atoms may bond with atoms of other elements, such as nitrogen, oxygen, and phosphorus (Figure 2b). Therefore, there are various non-equivalent definitions of atomic radius.
