The nuer of protons an atom has is called the atom’s atomic nuer, and determines the atom’s identity (e.g. carbon atoms have 6 protons, oxygen atoms have 8 protons). 3) Electrons : Electrons are negatively charged particles that are found in electron shells surrounding the nucleus.

Molecular Structure & Bonding - Chemistry

Distinguishing Carbon Atoms When discussing structural formulas, it is often useful to distinguish different groups of carbon atoms by their structural characteristics. A primary carbon (1º) is one that is bonded to no more than one other carbon atom. A secondary carbon (2º) is bonded to two other carbon atoms, and tertiary (3º) and quaternary (4º) carbon atoms are bonded respectively to
