the element carbon with six protons has the atomic number six. However, single elements can have different numbers of neutrons in the nucleus. For example, carbon has three naturally occurring 'isotopes' with six, seven, or eight neutrons. The sum of protons and neutrons in an atom's nucleus...
The final best-fit structure characterized by the minimum Pendry's reliability factor of 0.22 is as follows: one carbon atom in a unit cell of the graphite overlayer is located at the on-top site of the topmost Ni atoms, while another carbon atom exists at the fcc hollow site. The ...
Atomic Structure refers to the fundamental components of matter, namely atoms, which consist of a nucleus and orbiting electrons. The nucleus, acting as the center of an atom, is positively charged and has a much greater mass than the negatively charged electrons. Atoms are electrically neutral ...
Here we report a general method for the synthesis of a single atom catalyst with control of the atomic structure of the single atomic site as well as the mesoporous structure of the carbon support for optimized catalytic performance. Various combinations of metal centres (Ni, Co, Mn, Zn, Cu...

Q1. Sir James Jeans, who was a great populariser of science, once described atomic structure of carbon as being like six bees buzzing around a space the size of a football stadium.(a) (i) Suggest what were represented by the six bees in this description....
